CORTES, Armando et al. Iron deficiency in blood donors . Colomb Med [online]. 2005, vol.36, n.1, pp.34-39. ISSN 1657-9534.

CONTEXT: Blood donation results in a substantial loss of iron (200 to 250 mg) at each bleeding procedure (425 to 475 ml) and subsequent mobilization of iron from body stores. Recent reports have shown that body iron reserves generally are small and iron depletion is more frequent in blood donors than in non-donors. OBJECTIVE: The aim of this study was to evaluate the frequency of iron deficiency in blood donors and to establish the frequency of iron deficiency in blood donors according to sex, whether they were first-time or multi-time donors. DESIGN: From march 20 to April 5, 2004, three hundred potential blood donors from Hemocentro del Café y Tolima Grande were studied. DIAGNOSTIC TESTS: Using a combination of biochemical measurements of iron status: serum ferritin (RIA, ANNAR) and the hemoglobin pre and post-donation (HEMOCUE Vital technology medical). RESULTS: The frequency of iron deficiency in potential blood donors was 5%, and blood donors accepted was 5.1%; in blood donors rejected for low hemoglobin the frequency of iron deficiency was 3.7% and accepted blood donors was 1.7% in male and 12.6% in female. The frequency of iron deficiency was higher in multi-time blood donors than in first-time blood donors, but not stadistic significative. Increase nivel accepted hemoglobina in 1 g/dl no incidence in male; in female increase of 0.5 g/dl low in 25% blood donors accepted with iron deficiency, but increased rejected innecesary in 16.6% and increased is 1 g/dl low blood donors female accepted in 58% (7/12), but increased the rejected innecesary in 35.6%. CONCLUSIONS: We conclude that blood donation not is a important factor for iron deficiency in blood donors. The high frequency of blood donors with iron deficiency found in this study suggests a need for a more accurate laboratory trial, as hemoglobin or hematocrit measurement alone is not sufficient for detecting and excluding blood donors with iron deficiency without anemia, and ajustes hacia nivel more high in standars of accepted of hemoglobin no help the situation and no assure the blood suplly; increased exclusion blood donors of 9% at 44.6%.
