Diabetes Blood Test (HbA1c)

Testing your HbA1c levels is a way to measure your long-term blood glucose levels. This test measures the amount of sugar attached to your red blood cells. If you have high levels of HbA1c, it may indicate diabetes or pre-diabetes.


Why HbA1c?

Common reasons for this blood test are:

  • To check your risk of diabetes
  • To monitor your known diabetes
  • Examine your diabetes symptoms
  • Demonstrate the impact that lifestyle changes may have on your diabetes risk.

Your blood test

Our phlebotomy-trained professionals will take a blood sample from you. This sample will be analysed in the UK by our authorised partners, TDL. By booking this blood test, you agree for us to share your personal information with TDL in order to process your test. We’ll make sure you consent to this at your appointment too.

Frequently Asked Questions

No, we will send you the results and recommend that you share these with your GP or fertility provider.

It is not unusual for some bleeding to occur under the skin following your blood test and sometimes this can extend a little further around the puncture site.  If this causes you concern, check with your practice nurse. 

Sometimes we cannot get a blood sample from you. This can be for many reasons, such as not being hydrated enough, feeling cold or having another blood test recently. We will always offer you another appointment so we can try again.
