Abstract
Blood from 67 males whose blood donation was rejected because of blood gravity being less than 1.052 by copper sulfate screening were examined by laboratory studies such as red cell count, Hb concentration, hematocrit values, biochemical analyses and serological examinations. More than 70% of cases were found to have low levels of hemoglobin concentration (49 out of 67, less than 12.2g/dl) and serum iron contents (47 out of 67, less than 60μg/dl). Total iron binding capacity was high in 42% of cases (28 out of 67) and serum transferrin levels were also high in 33% of cases (22 out of 67). In 7% of cases (5 out of 67), GPT levels were higher than 36 unit. These laboratory findings suggest that 12 cases were considered to be healthy, but 10 cases were borderline between healthy and anemia, and another 33 cases were clearly designated as iron deficiency anemia. The 12 remaining cases were suspected of liver functional disorder with or without anemia. It is recommended from the results that those male donors, especially above 50 years of age, found to be ineligible or deferred to donate by copper sulfate screening test, have better to consult a doctor and have further examination of their blood. Therefore, doctors at blood center or on the blood donor coach should remind the background of blood gravity being less than 1.052 and give proper advice to the blood donors for their health and for their intension to donate blood.
