I noticed my cartridge and tubing have air bubbles in them. What could be the cause?
Bubbles naturally occur in all liquids, including insulin, when they undergo a fairly rapid temperature change, i.e. warm to cool.
To help to prevent bubbles, remove insulin from the fridge at least an hour before use. You should regularly check your cartridge and tubing for bubbles and prime out any that you find. Always remember to disconnect from your insulin pump before priming.
How do I order consumables for my Accu-Chek Combo insulin pump?
Ordering consumables and infusion sets for your Accu-Chek insulin pump online is only available to users who reside in the UK. Complete the online order form or contact Accu-Chek Customer Care.
In most cases your NHS Trust or Local Health Authority has authorised Roche to supply only selected consumables and quantities. If other goods are requested to be supplied this would first need to be authorised by your NHS Trust or Local Health Authority.
Please note: If you pay for your own pump consumables, or would like to order on behalf of someone else please contact Accu-Chek Customer Care.
Customers from the Republic of Ireland should obtain their pump consumables by prescription from their local chemist.
Accu-Chek Guide test strips are available with the Accu-Chek Guide Link meter, your companion to the Accu-Chek Solo micropump, and the Medtronic MiniMedTM 770G and 780G hybrid pumps.

Your HbA1c (also known as A1c or glycated haemoglobin) can give a general gauge of your diabetes management, because it provides an average blood glucose level over the past few months.
Use the calculator below to see the relationship between HbA1c and average blood glucose levels.
*The eHbA1c calculated here is just an estimation based on the average blood glucose you have entered. It should not replace the HbA1c check carried out by your doctor and the result shown here may differ from the lab value you get. This calculation should not be used to make therapy decisions or changes. You can discuss with your healthcare professional how this approximate measurement could help you in your overall diabetes management.
What is HbA1c?
You should have your HbA1c checked by your healthcare professional at least once a year, sometimes more depending on your diabetes. The HbA1c test measures your average blood glucose levels by taking a sample of blood. This is then sent to a lab to analyse the results.
Here's how it works:
Sugar (or glucose) naturally attaches itself to cells as they move through your bloodstream. When this happens, the cell is considered "glycated”. Everyone (whether they have diabetes or not) has glycated blood cells. The more sugar you have in your blood, the more that sticks to the cells. These are permanent, however as red blood cells only last for 4 months, new ones are made. That is why your HbA1c can only give an average of blood glucose over the last 2-3 months.
The more glucose in your blood, the higher the percentage of glycated red blood cells you'll have, and the higher your HbA1c result will be.
How is HbA1c measured?
HbA1c was previously measured in the DCCT (Diabetes Control and Complications Trial) unit of percentage (%), but in 2009, changed to the IFCC (International Federation of Clinical Chemistry) unit of millimoles per mol (mmol/mol). This was to make the unit of measure standard worldwide1. This means you might see your result displayed differently if you have had diabetes for a long time, or you will see two results, one in mmol/mol and one in %.
Unlike blood glucose readings using a finger prick test, which are reported as mmol/l, HbA1c is reported as a mmol/mol. For example, if you check blood glucose 100 times in a month, and your average result is 10.5 mmol/l this would lead to an HbA1c of approximately 66 mmol/mol (8.2%), which is above the recommended NICE targets.

What should my target HbA1c be?
You should determine the right target level for you, together with your healthcare professional. This will depend on your type of diabetes, your diabetes therapy, how long you have had diabetes and any previous HbA1c results.
According to NICE guidelines2, if you are an adult, have type 2 diabetes and are on diet and exercise, or medication that doesn’t cause hypoglycaemia- your target would likely be an HbA1c of 48 mmol/mol (6.5%).
If you are an adult with medication that does cause hypoglycaemia (i.e. insulin) your target will likely be an HbA1c of 53 mmol/mol (7%)2. This will depend on your individual circumstances however, so you should talk to your healthcare professional about the right goal for you
The importance of self-monitoring blood glucose and HbA1c
HbA1c is important, but it's not a substitute for structured self-monitoring. Only regular blood glucose checks show you how meals, activity, medications and stress affect your blood glucose at a single moment in time, as well as over the course of a day or week.
Without regular self-checking to provide day-to-day insights, an HbA1c result can be confusing. Because it gives an average view, a person with frequent highs and lows could have an in-range result that is the same as someone with blood glucose consistently in target range.
This is why self-monitoring blood glucose levels is valuable. Remember one blood glucose check in isolation will not tell you the whole story. Getting the results is one thing, but knowing what to do with them is key. Making the most of your data can help you to make better decisions, about your health, such as dietary choices and insulin doses.
The only way to get a complete picture of your blood glucose is by reviewing your day-to-day self-checks along with your regular HbA1c tests, and working closely with your Healthcare Professional to interpret the results. Find out more about blood glucose monitoring here.
