GlucoR AiDEX™ FAQ's

GlucoR AiDEX™ FAQs

GlucoRx AiDEX™ FAQs

Smart phone is not listed on the Compatibility list?

https://www.glucorx.co.uk/aidex-compatibility
Your phone model may not have been tested by GlucoRx. See if you can successfully download the GlucoRx AiDEX™ app on your smartphone before considering obtaining the CGM.

Who is GlucoRx AiDEX™ suitable for?

GlucoRx AiDEX™ is suitable for anyone over 14 years old who want to continuously monitor their glucose level (without fingerpricks), particularly patients with Type 1+2 diabetes and those concerned about their wellbeing, diet, fitness.

The GlucoRx AiDEX™ app does not work on my smartphone

Please check your display shows a 24hr clock as opposed to 12hr.

What size is GlucoRx AiDEX™ (sensor + transmitter when affixed on skin)?

35mm (L) x 21mm (W) x 9mm (H). This CGM is compact and comfortable to wear.

Is GlucoRx AiDEX™ a Flash monitor with a scan device?

No; GlucoRx AiDEX™ is a Continuous Glucose Monitoring System and does not

require scanning because it automatically sends readings to your iOS/Android

smartphone (GlucoRx AiDEX™ app) via Bluetooth every 5 minutes.

Tell me more about the sensor glue and stickiness.

The adhesive on GlucoRx AiDEX™ is made by 3M.

GlucoRx AidexTM kit is supplied with an overpatch to reinforce the adhesiveness if necessary.

What are the first steps?

Download the GlucoRx AiDEXTM app first and register before applying the transmitter and sensor.

Where do you wear the sensor?

A tiny flexible sensor filament is inserted beneath the skin in the interstitial fluid, worn on the abdomen (avoid applying within 5cm of any scar, insulin injection clog, sites close to belt or stretchmarks) or outside/back of the upper arm (avoid applying in muscle part of arm). Sensors inserted in muscle at the back of the arm may cause pain, bleeding. We recommend wearing on the abdomen, 3-10 cm away from the belly button, because of its thin subcutaneous fat – Take a deep breath and hold your belly firm before applying then relax to prevent misapplication.

How do you apply it?

The GlucoRx AiDEX™ sensor is applied to hair free skin using the applicator provided. Before application, use alcohol pads to disinfect your selected skin area and wait for a minute to let the skin dry. Hold the applicator firmly against your application site for 3 seconds for better adhesiveness. Use your fingers to smooth the edge of the adhesive pad. Then manually attach/click in the transmitter to the sensor base to allow the CGM to transfer readings by Bluetooth every 5 minutes to your iOS/Android smartphone (GlucoRx AiDEX™ app). Ensure all three transmitter hooks have been fixed on the sensor base and there are no big gaps between the transmitter and the sensor – you will hear 2 clicks if successfully assembled.

FYI there is no letter ‘O’ in the transmitter Serial Number; all ‘0’ are numerical zero.

What if my application site bleeds?

In the unlikely event that your sensor has been inserted into your capillary blood veins, you may bleed. You should apply pressure to the bleeding site until bleeding stops. If the sensor glucose value is showing consistent errors compared to your fingertip glucose value, replace the sensor. If bleeding persists after applying pressure to the wound for a few minutes, remove the sensor. Use another site and try again. If you are taking medicines such as aspirin which resists blood coagulation, this will not help the matter.

What if my adhesive pad falls?

Tips to prevent your adhesive pad falling:

  • Disinfect the skin site with alcohol wipes and allow to dry before GlucoRx AiDEXM CGM application.
  • Avoid applying shower gel or other chemicals on the adhesive pad (wash any chemicals off with water).
  • Use an overpatch to reinforce the adhesiveness.
  • Wear loose clothes to avoid them rubbing on the CGM.
  • Avoid applying GlucoRx AiDEXTM on loose skin.
What if there is no display after sensor warmup, with sensor stabilising message?

Your cannula may not have been inserted in interstitial fluid properly upon sensor application or there is clotted blood on the sensor tip. It usually takes 15-30 minutes to get the newest data. If your GlucoRx AiDEX™ App keeps showing “Sensor in Stabilising” after warmup (from subcutaneous bleed), wait up to 4 hours. If the problem persists after 4 hours, replace your sensor.

How do you avoid sensor malfunction?

Avoid touching the CGM or dislodging it with knocks/collisions. Avoid strenuous exercise or excess motion which could break the CGM during wear.

How is GlucoRx AiDEX™ powered?

There is a battery in the GlucoRx AiDEXTM sensor (14-day wear), which powers the transmitter.

How long is the activation after pairing?

Assemble the paired transmitter to the sensor within 5 minutes after application. Ensure your transmitter is assembled to your sensor within 30 minutes after application, otherwise the sensor may be deemed an expired sensor and will be unable to collect glucose data. When you have successfully paired the transmitter, you need to wait for one hour for your sensor to warm up. You will see the real-time glucose readings (updated every 5 minutes) on the ‘Home’ screen of the GlucoRx AiDEXTM App after sensor warm-up has finished. If the notification ‘Sensor detected’ appears again, click ‘A used one’ to ensure glucose measurement’s accuracy and continuity.


The transmitter must only be paired to one smart phone at a time. If you wish to change phone, you will need to unpair first and then pair again. The readings will not come through properly if the device is paired to two phones simultaneously.

How accurate is GlucoRx AiDEX™?

We have study data which supports the performance of the system has been established by its accuracy across all clinically relevant glucose ranges with respect to reference measurement.

Results from a study* by Linong Ji et al have shown GlucoRx AiDEXTM has a system accuracy of 98.69% (venous blood glucose) and overall MARD** of 9.08% when compared to venous blood reference.

* https://pubmed.ncbi.nlm.nih.gov/34378432/

**MARD = Mean Absolute Relative Difference; a measurement of on average how far away the sensor reading is from the Blood glucose reading. This is regardless of whether the reading is above or below the YSI value.

How long do the sensors and transmitter last?

The GlucoRx AiDEX™ sensor lasts for 14 days. GlucoRx AiDEX™ transmitter is reusable and lasts up to 4 years.

Difference between blood glucose and CGM values?

When blood glucose level is steady, fingertip blood glucose (BG) and Sensor glucose (CGM) have negligible difference. When blood glucose level is rapidly changing (after-meal, after-insulin or exercises), BG and CGM usually have noticeable difference. The reason for this difference is because of the delay between sensor glucose change rate and current blood glucose change rate.

How do I prevent inaccurate results?

Your fingertip blood glucose may not have been measured correctly (eg. contaminated blood sample) and should be repeated. Rapid changing in blood glucose could lead to a slight delay in sensor glucose measurement. Also, sensor application site is under external forces and may lead to undermeasurement of blood glucose value. Only calibrate while your blood glucose level is steady. It is recommended not to calibrate within 24 hours after CGM application and just once each day.

The calibration button is greyed out.

You cannot calibrate in the first 6 hours of applying a new sensor. After 6 hours has passed, the option to calibrate will be enabled.

Please also ensure the GlucoRx AiDEX™ app is up-to-date and try the following: Go to Settings -> Profile – > Logout – then Log in again to hopefully fix the calibration issue.

What is the recommended time to calibrate GlucoRx AiDEX™?

The best time to calibrate GlucoRx AiDEX™ is first thing in the morning before any food or drink is consumed (fasting state from overnight).

Can I share data?

GlucoRx AiDEX™ app is integrated with GlucoRx AiDEX™ Web Dashboard (https://grxaidex.com/auth/login) and GlucoRx Voyager (https://www.grxvoyager.com/), from which you can export results.

Data appears on mobile app and watch but not in GlucoRx Voyager app?

Log out of the GlucoRx AiDEX™ App on your smartphone and log in again – this should update data in Voyager.

Does the GlucoRx AiDEX™ app speak to you?

The GlucoRx AiDEX™ app does not give audio feedback

Does this CGM work with all Apple watches?

Once you download the GlucoRx AiDEX™ app on an Apple phone and if this phone is integrated with an Apple watch, then the app will appear on the watch and you should be able to see the results on your phone. You will require your phone to be nearby.

Notifications not coming up on Apple watch

Currently alerts and alarms are not possible but in the next release of the GlucoRx AiDEX™ App, a new Smart Alarm feature will be added with improved alarms and alerts sounds.

Does this CGM work with Android watches?

Not supported yet.

Is GlucoRx AiDEX™ approved for UK blood sugar levels?

GlucoRx AiDEX™ CGM is a certified CE device.

Is this device DVLA approved or is it necessary to continue finger prick testing?

https://diabetestimes.co.uk/dvla-approves-cgm-devices-for-driving-with-diabetes-28347-2/

As announced on 15th February 2019, Flash and Continuous Glucose Monitoring devices can now be used to take glucose readings by insulin-dependent drivers.

Logged into AiDEX™ app but forbids login (error 403) after?

Have you verified your AiDEX™ email on time? – Could be in your junk folder or password issue (try to change password).

Is GlucoRx AiDEX™ waterproof?

GlucoRx AiDEX™ has a water rating of IPX7, which means it is waterproof and can withstand incidental exposure to water of up to 1 metre for up to 30 minutes. Avoid applying shower gel on the CGM adhesive pad when showering. Use an overpatch to reinforce the adhesiveness if necessary. If moisture enters the gap between sensor and transmitter, detach the transmitter from the sensor to wipe and try again.

Can vaccines be given intramuscularly in the deltoid region of the same upper arm the Aidex Sensor is worn, how far away from the sensor can they be injected and would there be a change in readings?

Theoretically intramuscular injection should not affect subcutaneous interstitial glucose readings by GlucoRx AiDEX CGM; We would expect there to be no effect on glucose readings as long as the injection site is 5cm away from the sensor.

Does paracetamol affect the functioning of GlucoRx AiDEX™?

Standard or maximum acetaminophen (Paracetamol) dose of 1g (1000mg) every 6 hours does not affect the GlucoRx AiDEX™ system sensor readings. Taking higher than the maximum dose of acetaminophen (Paracetamol) (eg >1g every 6 hours in adults) may give false sensor glucose readings.

GlucoRx AiDEX™ at airports and scans

This CGM can be worn through airport scanners. To prevent signal loss when you put your smart phone in aeroplane mode, ensure you also enable Bluetooth.

GlucoRx AiDEXTM should be completely removed before any Magnetic Resonance Imaging (MRI) scan or Computerised Tomography (CT) scan. The device is immune to mobile phone magnetic field.

Can this CGM be worn when on a sunbed?

Yes, but avoid direct contact with the sunbed.

Can you return and recycle the used applicators with GlucoRx AiDEX™?

GlucoRx AiDEX™ Sensor packaging can be disposed of in general waste. The Applicator which contains the needle, once used, must be discarded in a biohazardous bag or sharps box. Once the GlucoRx AiDEX™ sensor is worn and used, this should then be disposed in a biohazardous bag or sharps box. GlucoRx AiDEX™ transmitter is reusable and can last up to 4 years.

What are the advantages over GlucoRx AiDEX™ sensor in comparison to the competition and does it link to any insulin pumps?

We advise users to compare the specifications with that of the competitor.

GlucoRx AiDEXTM CGM is not licenced for closed loop, however GlucoRx plans to have a Hybrid closed loop system with its Equil patch pump in the near future.

How much is GlucoRx AiDEX™ kit?

The GlucoRx AiDEX™ starter kit is £99.85+VAT and includes 1x reusable transmitter and 2x 14-day sensors, all for use with the free GlucoRx AiDEX™ App.

Our subscription plan will be available on the GlucoRx website early 2022.

Am I eligible for VAT exemption?

People with diabetes are exempt from paying VAT; select VAT exemption on check out when purchasing from the online shop on GlucoRx’s website.

The CGM system comes with 2 x 14-day sensors; what is the ongoing cost of replacement sensors?

Each GlucoRx AiDEXTM CGM Sensor RRP is £39.95 plus VAT (if applicable)

Each sensor lasts 14 days.

GlucoRx Nexus FAQs

This FAQ covers the GlucoRx Nexus TD-4277, Nexus mini TD-4287 & Nexus Voice TD-4280. For specific information on GlucoRx Nexus Blood Glucose Monitoring System, please see Owner’s manual.

What happens when I see the ‘E-b’ symbol?

When this low battery symbol warning is displayed on screen after about 500 readings, your meter is functional and the result remains accurate for about 50 more readings but you are advised to change the battery by 20-25 readings.

What is the haematocrit?

30 – 60% (glucose strips)

Do I need to code my Nexus meter?

These machines are all non-coding.

What about when the clocks go backwards and forwards?

The Nexus meters cannot automatically update Daylight saving time. They display 7-, 14-, 21-, 28-, 60- and 90-day averages which you can access from the meter memory; these may change when the date and time are changed.

Where is the SET button located?

You can change the settings by accessing the small “Set” button behind the battery panel at the back of your meter.

Are the Nexus meters whole blood or plasma referenced results?

Results from the Nexus range are plasma calibrated from whole blood.

 
Would I lose the meter memory when changing the battery?

Replacing the batteries does not affect the test results stored in memory

 
Can the meter memory be deleted?

The new Nexus meters do not have a memory deletion function. When the memory is full, the last result disappears with every new result that is added.

 
Can lancets be reused?

To reduce the chance of infection, never share a lancet or the lancing device with others. Always use a new, sterile lancet that is in date as they are disposable and intended for single use only.

 
What is the shelf life of the Nexus test strips and Control solution?

Nexus strips – close the vial immediately after taking out a strip. Use each test strip immediately after taking it out of the vial. Do not use the test strips if they have expired (the expiry date printed on Nexus strips can be up to 18 months from Manufacture).

Control solution – 3 months from opening.

How do I keep my Nexus system clean?

To avoid these diabetic products getting dirt, dust or other contaminants, wash and dry your hands thoroughly before use.

Meter exterior – wipe with a cloth moistened with tap water or a mild cleaning agent (not organic solvents), and then dry with a soft cloth.

Lancing device (this is reusable) – use a mild soap and water to clean the lancing device; do NOT rinse under water, use detergents or place in a dishwasher. Disinfect the AST cap before allowing to air dry.

What free accessories are available for the Nexus range?

Registered GlucoRx users are eligible for free/spare batteries, bottles of TaiDoc control solution, blood glucose monitoring diaries, PC link cables, AST caps, lancing devices, carry case, instruction manuals upon request through www.glucorx.co.uk/our-services/free-accessories, or by phoning GlucoRx Customer care on 01483 755133.

What about if I need a spare or more compact meter for my travels?

Feel free to request via GlucoRx Customer care by telephoning 01483 755133 or e-mailing [email protected].

Are the Nexus meters covered by a lifetime warranty?

GlucoRx is committed to ensuring that your meter(s) and testing requirements are fulfilled and covered by a lifetime warranty.

Can the Nexus system be used on newborn babies or the critically ill?

The system must NOT be used in either of these patient groups.

Where can I order more control solution from?

Registered GlucoRx users are eligible for free bottle of control solution upon request through this website, or phoning GlucoRx Customer care on 01483 755133.

Why is the control solution test important, and how often should it be performed?

Control solutions contain a known amount of glucose that reacts with the test strips. By comparing your control solution test results with the expected range printed on the test strip vial label, it is possible to check that the meter and the test strips are working together as a system and that you are performing the test correctly.

You should perform a single test at least once a week to routinely check your meter and test strips, particularly when you:

1. First get your Nexus meter / you want to practice running the test.

2. Drop the meter.

3. Begin using a new vial of test strips, or the strips are exposed to extreme environmental conditions.

4. Suspect that the meter or test strips are not working properly, your results are inaccurate or have blood glucose test results that are not consistent with how you feel.

Where do I find the control solution range?

The range is printed on the test strip pot – Level 2, in mmol/L.

What happens if my control result is out of range?

If the result falls outside the specified range, see ‘Problems in Operation’ in your Owner’s manual and repeat the test. If you continue to get out-of-range results, it means your Nexus system may not be working properly. Do NOT test your blood in this case. Check the expiry of the control solution and test strips as well as the Nexus meter for any damage (if it has been dropped or immersed in liquid).

Where do I obtain my Nexus test strips and GlucoRx lancets from?

These are available on prescription from your GP surgery. Alternatively you can purchase from any pharmacy or directly from our website.

What are the performance characteristics of Nexus?

The latest ISO 15197:2013 specifies 95% of glucose results must be within ±15% of a reference standard (for results at or above 5.55mmol/L) and within ±0.83mmol/L (for results below 5.55mmol/L). 99.8% results from Nexus fulfil the minimum system accuracy requirements of this ISO standard.

Why do people with diabetes have to monitor their blood glucose?

Frequent testing of blood glucose levels allows people with diabetes to take control of their own health, particularly: understanding the effect of medical treatment on their blood glucose; making adjustments in their food intake when increasing physical activity; preventing acute complications such as hypo- and hyperglycemia; knowing when changes in insulin dosage or oral therapy may be needed.

Which Testing strips do all three Nexus meters take?

The strips for the Nexus range utilise FAD-dependent glucose dehydrogenase (GDH-FAD) enzymes for blood glucose measurements. GDH-FAD technology, the most advanced enzyme system, avoids interference from blood oxygen variations and can be applied to capillary and venous blood samples. These GDH-FAD strips have no significant reactivity to any non-glucose sugars (i.e. maltose) at therapeutic or physiological levels.

What should my blood sugar level be?

You should always consult your Diabetes care team to determine a target range that works best for you. Normal blood glucose range for people with diabetes: Fasting and before meal – 4 to 7 mmol/L 3 hours after meals – less than 9 mmol/L. *Source Diabetes UK. Blood glucose target. Balance: No.234, 2010 April. P.69. For some people, such as children or those at risk of hypoglycaemia, the recommended guidelines may be broadened.

What should I do if I get a questionable reading?

Ensure the blood sample completely fills the confirmation window of the test strip, check the test strips have not expired, do a control solution test and even repeat with strip from another pot/batch. Consult your diabetic nurse if results continue to be too high or low.

Which factors affect blood glucose monitoring?

There are many factors affecting blood glucose monitoring and accuracy which GlucoRx educates its dispensing surgeries on, namely correct meter calibration, hand washing, blood sampling tech-nique/quality, meter and strip storage/usage (temperature, humidity), and certain medications taken by the user. Please find further details on https://www.glucorx.co.uk/diabetes/factors-affecting-accuracy/

What happens if I am unable to extract enough blood?

Try adjusting the 6 depth settings on your GlucoRx Lancing device.

What is Alternative Site Testing?

The Nexus systems enable testing on the palm, forearm and upper arm. Use the clear cap included in the kit when setting the lancing device. Only do AST in a pre-meal or fasting state (more than 2 hours since last meal); two hours or more after taking insulin; two hours or more after exercise.

Do the Nexus meters test for ketones?

n diabetics, the buildup of ketones (chemicals produced in the liver from the breakdown of fat) is a sign of very poor diabetes control. An excess of ketones can cause ketoacidosis. The Nexus TD-4277 and Nexus Voice TD-4280 machines display a ketone warning (not actual ketone reading) over 15mmol/L if they believe the user needs to get their ketone levels checked at the Doctors.

How often should I test my blood glucose levels?

There are no rules about how often one should test as different people will have different regimes. Test as many times as it takes to feel confident about your blood glucose control, however, not everyone may be happy testing several times a day and some may not be prescribed enough test strips.

It is advisable to test either side of meals, once before eating and again after the meal to gauge how different meals affect your sugar levels. It is a good idea to test before and after sleep until you have a good idea of whether your sugar levels are rising, falling or stabilising overnight.

How do I download my readings?

1. Install the GlucoRx Healthcare Management system on your PC using weblink: https://www..glucorx.co.uk/our-products/software/. This is compatible with Windows based programmes but not Apple Mac.

2. Connect one end of the interface cable (obtained from GlucoRx Customer care team) to a serial port on your PC, and the other end to the data port of the meter (should be switched off).

3. “PC” should appear on screen.

4. Follow the instructions provided in the software to transmit data.

5. Remove cable when done and your meter should automatically switch off.

If you have problems with this process, repeat the installation and also try downloading on another computer.

What is the difference between HbA1c (glycated haemoglobin) and blood sugar?

Self-testing of blood sugar at home gives your blood sugar level at the exact time of the test. The HbA1c test is done at your doctor’s office. It shows your average blood sugar over a sustained period of time, usually 90 days.

This FAQ covers the GlucoRx HCT range. For specific information on GlucoRx HCT Blood Glucose Monitoring System, please see Owner’s manual.

Do I need to code my GlucoRx HCT system?

With this meter system, the glucose test is non-coding. A simple coding step is only required with the ketone test/strips.

Once the user receives their kit, the meter is already pre-coded and does not require coding to use the one ketone strip enclosed within. Every additional box of 10x GlucoRx HCT Ketone tests strips encloses a ketone code chip, which has to first be inserted in the meter when the user wants to test their ketones. The code displayed on the meter/phone screen from this code chip must match that printed on the foil packaging of the enclosed ketone strips, before ketone measurement can commence with a ketone test strip from that box.

Ketone coding needs to be performed thereafter with every code chip enclosed in successive boxes of ketone strips used.

What about when the clocks go backwards or forwards?

The GlucoRx HCT & Ketone meter cannot automatically update Daylight saving time. It displays 7-, 14, 21-, 28-, 60- and 90-day averages which you can access from the meter memory; these may change when the date and time are changed.

Where is the SET button located?

You can change the settings by accessing the small “Set” button behind the battery panel at the back of your meter.

Can my GlucoRx HCT system be used on newborn babies or at high altitude?

The blood glucose test strip can be used for the testing of newborns.

The β-ketone test strip must NOT be used for the testing of newborns.

When using both glucose and ketone strips, altitudes of up to 10,742 feet (3,275m) do not affect test results (this information is stated in the individual strip inserts).

What is the difference between HbA1c (glycated haemoglobin) and blood sugar?

Self-testing of blood sugar at home gives your blood sugar level at the exact time of the test. The HbA1c test is done at your doctor’s office. It shows your average blood sugar over a sustained period of time, usually 90 days.

How do I download my readings?
  1. Install the GlucoRx Healthcare Management system on your PC using weblink: https://www..glucorx.co.uk/our-products/software/. This is compatible with Windows based programmes.
  2. Connect one end of the interface cable (obtained from GlucoRx Customer care team) to a serial port on your PC, and the other end to the data port of the meter (should be switched off).
  3. “PC” should appear on screen.
  4. Follow the instructions provided in the software to transmit data.
  5. Remove cable when done and your meter should automatically switch off.

If you have problems with this process, repeat the installation and also try downloading on another computer.

Where do I obtain my GlucoRx HCT glucose/ketone test strips and GlucoRx Lancets from?

These are available on prescription from your GP surgery. Alternatively you can purchase from any pharmacy or directly from our website.

How often should I test my blood glucose levels?

There are no rules about how often one should test as different people will have different regimes. Test as many times as it takes to feel confident about your blood glucose control, however, not everyone may be happy testing several times a day and some may not be prescribed enough test strips.

It is advisable to test either side of meals, once before eating and again after the meal to gauge how different meals affect your sugar levels. It is a good idea to test before and after sleep until you have a good idea of whether your sugar levels are rising, falling or stabilising overnight.

Does my GlucoRx HCT system give a ketone warning?

In diabetics, the buildup of ketones (chemicals produced in the liver from the breakdown of fat) is a sign of very poor diabetes control. An excess of ketones can cause ketoacidosis. The GlucoRx HCT system displays a ketone warning over 15mmol/L if it believes the user then needs to do a ketone test.

What is Alternative Site Testing (AST)?

The GlucoRx HCT system enables AST with the ketone test only on fingertips/palm. Use the clear cap included in the kit when setting the lancing device. Only do AST in a pre-meal or fasting state (more than 2 hours since last meal); two hours or more after taking insulin; two hours or more after exercise.

What happens if I am unable to extract enough blood?

Try adjusting the 6 depth settings on your GlucoRx Lancing device.

 
How can I improve the accuracy of my result?

Select the puncture site either on your finger or other body parts (AST). Choose a different spot for each test as repeated puncture in the same areas may cause soreness and callouses. Clean the site with warm water and let it air-dry completely before pricking. Improve blood flow to the site by warming it and gently massaging. Press the lancing device firmly against your skin. Gently squeeze the punctured area, discard the first drop of blood and obtain at least 1.0µL of blood from the purer sample that emerges from underneath; do NOT smear it.

Which factors affect blood glucose monitoring?

There are many factors affecting blood glucose monitoring and accuracy which GlucoRx educates its dispensing surgeries on, namely correct meter calibration, hand washing, blood sampling technique/quality, meter and strip expiry/storage/usage (temperature, humidity), and certain medications taken by the user. Please find further details here.

What should I do if I get a questionable reading?

Ensure the blood sample completely fills the confirmation window of the test strip, check the test strips have not expired, do a control test and even repeat with strip from another pot/batch. Consult your diabetic nurse if results continue to be too high or low.

What should my blood sugar, ketone, haematocrit and haemoglobin level be?

You should always consult your Diabetes care team to determine a target range that works best for you.

Normal blood glucose range for people with diabetes (Source Diabetes UK. Blood glucose target. Balance: No.234, 2010 April. P.69):

Fasting and before meal – 4 to 7 mmol/L
2 hours after meals – less than 9 mmol/L.

For some people, such as children or those at risk of hypoglycaemia, the recommended guidelines may be broadened.

Ketone reading (Source: adapted from Information provided in The Balance Guide to Meds & Kit, 2011 – 2012, p15)
Below 0.6mmol/L – Normal blood ketone level
Between 0.6 and 1.5 mmol/L – More ketones are being produced than normal; contact your Diabetes healthcare team for advice.
Above 1.5mmol/L – Risk of Diabetic ketoacidosis; call your Diabetes healthcare team immediately.

Typical Haematocrit (Source: www.emedicinehealth.com):
Newborns: 55-68%
1 year olds: 29-41%
10 year olds: 36-40%
Adult men: 42-54%

General Haemoglobin results (Source: http://www.nlm.nih.gov/medlineplus/ency/article/003645.htm):
Newborn: 14 to 24 g/dL
Infant: 9.5 to 13 g/dL
Male: 13.8 to 17.2 g/dL
Female: 12.1 to 15.1 g/dL[/vc_column_text][/vc_tta_section][vc_tta_section title=”Which type of ketone does my GlucoRx HCT system test for?” tab_id=”1472553211841-2a2660e5-1901″][vc_column_text]

The β-Ketone test measures Beta-Hydroxybutyrate (ß -OHB), the most important of the three β-Ketone bodies in the blood.

[/vc_column_text][/vc_tta_section][vc_tta_section title=”Is my GlucoRx HCT system affected by maltose and/or icodextrin?” tab_id=”1472553212466-6045a124-0218″][vc_column_text]

The GlucoRx HCT system is suitable for patients on Peritoneal dialysis; – The Test strips for this machine uses GDH-FAD enzyme technology which has no reactivity to any non-glucose sugars such as Maltose (which is what icodextrin is converted to).

Explain the enzyme technology my GlucoRx HCT system utilises?

GDH-FAD technology, the most advanced enzyme system, avoids interference from blood oxygen variations and can be applied to capillary and venous blood samples. These GDH-FAD strips have no significant reactivity to any non-glucose sugars (i.e. maltose) at therapeutic or physiological levels.

GlucoRx HCT glucose test strips use advanced GDH-FAD enzyme technology with 2+2 (AC and DC) Bio Signal. AC signal works to provide the haematocrit result, and DC calculates glucose.

Device then corrects glucose level according to haematocrit value.

What are the performance characteristics of GlucoRx HCT system?

The latest ISO 15197:2013 specifies 95% of glucose results must be within ±15% of a reference standard (for results at or above 5.55mmol/L) and within ±0.83mmol/L (for results below 5.55mmol/L). 100% results from GlucoRx HCT & Ketone meter fulfil the system accuracy requirements of this ISO standard.

Why do people with diabetes have to monitor their blood glucose?

Frequent testing of blood glucose levels allows people with diabetes to take control of their own health, particularly: understanding the effect of medical treatment on their blood glucose; making adjustments in their food intake when increasing physical activity; preventing acute complications such as hypo- and hyperglycemia; knowing when changes in insulin dosage or oral therapy may be needed.
