What is the HbA1c lab test?
The HbA1c lab test measures HbA1c. It is used to show blood glucose
level control over the past 2 to 3 months
1
. The HbA1c lab result is
expressed as a percentage of haemoglobin bound to glucose. For
example, an HbA1c of 7% means 7% of your haemoglobin is bound
to glucose. The higher your blood glucose level, the more glucose
binds to the haemoglobin in your blood and the greater your
HbA1c test result.
The MyStar Extra® does not give you an HbA1c value. It only
gives an ~A1c value and may di er substantially from an actual
HbA1c result that you get when you visit your healthcare
professional and have blood drawn in the laboratory. The ~A1c
should not be used to predict your actual HbA1c.
WARNING: This tool uses blood glucose readings to estimate your
A1c based on a mathematical formula. It is not a substitute for a
laboratory test performed by your healthcare professional. Your
~A1c value may di er substantially from results obtained through
an HbA1c test. Do not use the ~A1c to make treatment decisions.
If you have questions about your ~A1c, please contact your healthcare
professional.
