Several labs and patient related factors can result in falsely increased or decreased glycated hemoglobin values. The presence of hemoglobin variants is one of the most important factors. We report a rare case of persistent fetal hemoglobin manifesting as a falsely high HbA1c in a 55-year-old lady with coronary artery disease. Her blood glucose level was normal(RBS was 111mg/dL) though HbA1c was incongruently high (57.1%) by HPLC. Further, hematological investigations and Hb variant analysis revealed that she had hereditary persistence of hemoglobin F(HPFH). Her actual HbA1c was found to be 5.9% by the immunoturbidimetric method. It is important for clinicians to be aware of the factors that could affect glycated Hb estimations in the laboratory, as clinical treatment is often based on lab data.
