The usefulness of glycosylated hemoglobin (HbA1C) in discriminating between iron deficiency and thalassemia

Abstract

This study assessed whether glycosylated hemoglobin could be used as an index to distinguish between iron-deficiency anemia and thalassemia minor. Glycosylated hemoglobin was measured by high-pressure liquid chromatography in 40 ss -thalassemia minor patients, 20 iron-deficiency anemia patients, and 38 healthy controls, all nondiabetic. Median glycosylated hemoglobin was lower in ss -thalassemia minor than in the iron-deficiency and control groups (p = .000). There was no difference between iron-deficiency patients and healthy controls (p = .095). Glycosylated hemoglobin was not different in iron-replete and iron-deficient traits (p > .05). A cutoff value of 5% has provided a sensitivity of 95% and specificity of 75.7% for distinguishing between these two entities. Positive and negative predictive value were 96.6 and 67.9%. These values were superior to the traditional discriminants' values calculated on the same individuals. Glycosylated hemoglobin could be useful in discriminating between iron-deficiency anemia and thalassemia minor. Further studies are needed, but the point that it can also be used when both conditions exist simultaneously seems to be clinically important.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
