HbA1c Level


After diagnosis of diabetes mellitus it is a must to perform self-monitoring of blood glucose.
 
When an appropriate therapy has been started its efficiency has to be proofed through the HbA1c level which is tested from a blood sample in the doctor’s office. It defines the percentage of haemoglobin (red colorant of blood) which is associated with glucose.
 
The normal range is 4-6% in direct dependency from blood glucose. The level of HbA1c gives evidence about blood glucose levels of the last 8 to 12 weeks. An optimal therapy should lead to an HbA1c lower than 7% to prevent late complications.   
 
HbA1c Equation:
Average blood glucose [mg/dl] = 33,3 x HbA1c [%] - 86
 
Since April 1 2008 the HbA1c-value will be specified (also) in mmol/mol.
Conversion formula: HbA1c [mmol/mol] = (HbA1c [%] - 2,15) x 10,929
