HbA1c Calculator

This uses the statistical estimate eAG = 28.7 × HbA1c − 46.7. HbA1c back-calculated from eAG is not a laboratory result and cannot diagnose disease. Anemia, blood disorders, kidney/liver disease, pregnancy, bleeding/transfusion, and some medicines can affect HbA1c accuracy.

For a reading accompanied by confusion, fainting, severe weakness, trouble breathing, repeated vomiting, or dehydration, stop and get urgent medical help.
