Are you in the UK? Different countries may use different units for measuring glucose levels, and there are also several tests that can be done and these use different units too.
It's worth asking your practice receptionist for a printout of your recent test, so that you know exactly which test was done. I can get copy free but I believe some practices may charge for this.
One test is done your meter (or by a finger prick by the nurse) which measures the level of glucose in your blood at the time it's actually checked, and here in the UK this is measured in
mmol/L - e.g.6.4 mmol/L
Another standard test (HbA1c) is done at 3, 6, or even 12 monthly intervals, and measures your average glucose levels over the previous 3 months. This is done by taking more blood froma needle (usually from the inside of your elbow. This used to be measured as a percentage - e.g.
6.4% but
this figure is not the same as the regular meter tests you do. Currently your HbA1c test is now measured as
mmol/mol in the UK to avoid confusion. So the old
6.4% would equate to
47mmol/mol, which in turn would be equivalent to regular meter readings of
7.6mmol/L.
Have a look
here on the main Diabetes UK site to see what the different figures mean diabetes-wise. It will also give links to information on HbA1c checks, and to conversion tables for all the different unit.
