Effect of iron deficiency anaemia on HbA1c levels is dependent on the degree of anaemia.

Objectives: Studies suggest that iron deficiency anaemia (IDA) is associated with higher HbA1c levels. We conducted a control–case study to investigate the effect of IDA on HbA1c levels, measured by two commonly used methods, in non-diabetic individuals.

Design And Methods: A total of 122 patients were included, 61 patients with IDA and 61 patients without anaemia.
