Abstract

Estimation of haemoglobin (Hb) plays an important role in the medical examination of prospective blood donors. Various tests to estimate Hb are available in the market to screen for donor Hb with their own set of advantages and disadvantages. Each Blood centre chooses their test based on the availability of funds / resources, manpower and number of donations. Like any other test, Hb estimation tests also have various factors resulting in erroneous results. Identifying and preventing such factors is crucial in maintaining the safety of donor and the patient. This short research communication dwells upon such common factors influencing Hb estimation in the routine blood donor screening and what can be done to prevent such errors.
