Abstract
A haemoglobin A1c (HbA1c) is an essential marker for assessing long-term glycemic control and diagnosing diabetes mellitus. However, iron deficiency anaemia (IDA), one of the most common nutritional disorders worldwide, may alter HbA1c levels even in non-diabetic individuals, leading to misinterpretation of glycemic status. This study aims to examine the effect of IDA on HbA1c levels in Libyan patients with and without diabetes, while also exploring the correlation between HbA1c levels and the iron profile.
