The voluntary unpaid blood donation is a humanitarian act towards the sick by the healthy. No transfusion service can survive without blood donors. The wellbeing and health of the blood donors is of prime importance for the medical profession. A lot has been discovered and written about protection of the recipients from the potential hazards of blood transfusion. A lot of money is being spent for the screening of donors for protection of recipients but very little attention is given to the health status of donors. The main reason is the fear of losing the donor in a time when the demand of blood is soaring all over the world and the donors are becoming scarce.1 Chronic iron deficiency is a well-recognized complication of regular blood donation.2, 3 After a single donation, a person needs approximately 3 months to replenish iron stores.4 In the majority of blood banks, hemoglobin (Hb) measurement is used as a screening test for the ability to donate blood. Since hemoglobin levels may be normal in the presence of reduced iron stores.5, 6 The use of this parameter has been reported to have poor sensitivity in the detection of early stages of iron deficiency.1 Indeed, an accurate diagnosis of a state of iron deficiency requires several laboratory tests. Measurements of serum ferritin concentrations and red cell indices such as mean cell volume (MCV) and mean corpuscular haemoglobin (MCH) can be used with a high degree of accuracy and precision.7, 8 Previous studies have shown that the serum ferritin levels were reduced markedly in regular donors corresponding to annual donation frequency.5, 9 In order to fulfill the global and national drive to recruit and retain regular repeat voluntary blood donors, the iron status of the donors needs to be identified and necessary steps for iron supplementation need to be taken. There is paucity of data in India country, particularly in and around Surat city regarding impact of regular voluntary blood donation on iron status of donors. The present study was, therefore, designed to assess (using a combination of hematological and iron status parameters) the development of anaemia and prevalence of iron deficiency anaemia in the voluntary blood donors in Surat city donors.
