HbA1c Conversion

Average glucose and IFCC

For education. Check every result.

Anatium is a study resource, not medical advice. Nothing here is a diagnosis, a prescription or a substitute for a clinician who has seen the patient. Check every number against a current local protocol before it touches anyone, and never act on a result you cannot reproduce yourself.

Fill in every field above, then select Calculate.

How it is calculated

Estimated average glucose from the ADAG study relationship. HbA1c is unreliable where red-cell lifespan is altered - haemoglobinopathies, haemolysis, recent transfusion, iron deficiency, pregnancy and advanced kidney disease all distort it, in either direction.

About

Converts HbA1c to estimated average glucose and to IFCC units, and places it against the diagnostic thresholds. HbA1c is unreliable wherever red-cell lifespan is altered.
