Studies across the world have shown that HbA1C is elevated in non–diabetic patients also suffering from hypothyroidism. The falsely elevated HbA1C level in Hypothyroid patients  is often explained by anaemia  which is a common associated feature . In  this study it was  investigated whether elevated A1C in non diabetic hypothyroid patients can be due to anaemia. Between March 2016 to September 2016, 63 nondiabetic hypothyroid individuals were tested in the Dept. of Biochemistry ,NRSMC & H for TSH ,fT4,fasting blood glucose,HbA1C & complete haemogram. Non–diabetic hypothyroid individuals with anaemia showed elevated HbA1C levels (5.00 +– 0.35 % ) than those without anaemia (3.59+– 0.27 %), the rise was approx. 1.39 times. Altered erythrocyte life span is partially responsible for this false elevation in HbA1C levels. Hence  this conversion factor might be used to correct the haemoglobin status while using HbA1C as a diagnostic tool for diabetes in such patients.
