Influence of Iron Deficiency Anemia on HbA1c: A Review
CURRENT RESEARCH IN DIABETES & OBESITY JOURNAL JUNIPER PUBLISHERS Authored by Ghulam N Bader Abstract Hemoglobin A1c (HbA1c) is widely used as a diagnostic tool for diabetes. Many clinical conditions affect erythrocyte turnover which influence HbA1c levels. These levels are lowered by different forms of anemia, but reverse is the case in iron deficiency anemia (IDA). This is suggested by various studies which propose an increase in HbA1c levels in patients with IDA. However, there are studies which negate any influence of IDA over HbA1c levels. In both cases the clinical data is not sufficient to confirm or nullify the role of IDA in increasing HbA1c levels. Go to Introduction Hemoglobin A1c (HbA1c), a glycated hemoglobin is formed by an irreversible, slow non-enzymatic catalysis of the β chain of globin in mature hemoglobin (Hb) [1,2]. It is used as a gold standard for monitoring glycemic status for the previous three months (the life span of a red blood cell) in patients with
