Valores de hemoglobina y hematocrito en más de 100 mil donantes del banco de sangre del Hospital Pablo Tobón Uribe, Medellín-Colombia (1538 msnm)

Objective: Determine hemoglobin and hematocrit values in blood donors between the years 2000-2009. Methods: An observational descriptive study with a sample of 103,690 donors composed of men and women adults who voluntarily donated blood in the blood bank of the Hospital Pablo Tobon Uribe (HPTU). The variables evaluated in the study were sex, age, hemoglobin and hematocrit. Results: The 50,7% of the sample composed of males, 90,7% of donors living in Medellin, the average age was 32,5 (±11,5) years. In men the average hemoglobin and hematocrit was 15,96g/dl (±1,11) and 46,93% (±3,27), respectively, in women the average was 14,10 g/dl (±1,00) and 41,64% (±2,96) respectively. Conclusions: The hemoglobin and hematocrit values are determined by variables such as sex, age, ancestry and height above sea level, therefore it is important that each population know about their values in relation to their own determinants.
