The system generates calculations for HbA
1c
and Glomerular Filtration Rate
(GFR). You can customize the result reporting units according to your clinical
practice or lab requirements.
Percent HbA
1c
Calculation
The system calculates the values for HbA
1c
for patient tests. To calculate the
HbA
1c
percentage, the system uses the concentration of HbA
1c
divided by the
total hemoglobin concentration.
% HbA
1c
= (HbA
1c
/Total Hemoglobin) x 100
