EVALUATION OF BLOOD COUNT AMONG BLOOD DONORS ATTENDING KOSTI TEACHING HOSPITAL BLOOD BANK, WHITE NILE STATE, SUDAN

Abstract

Objectives: Current study aimed to evaluate blood counts among blood donors attending Kosti hospital blood bank. Methodology: This cross sectional descriptive study was performed at the blood bank of Kosti teaching hospital during Decem- ber 2014-Febrauray 2015 and aimed to determine the haematological parameters of blood donors. One hundred donors were chosen randomly to participate in this study. Venous blood (2.5ml) was obtained from each individual into an EDTA container. The full blood count (FBC) was done for each donor, using fully automated haematology analyzer (Sysmex). Peripheral blood film for morphology was done using Giemsa stain. Results: Results showed that haemoglobin concentration was normal in 55% of the donors, less than the normal in 43% and above the normal in 2% of studied group. RBCs were 70% normal, 4% lower than normal and 26% higher than normal. 78% of the donor showed WBC within normal range and the remaining 18% were lower than normal. Platelets counts in donors were 90% normal, 8% low and 2% high. The Haematocrit values were 87% normal, 7% low and 6% high. The MCV in donors was 74% normal and 26% low. MCH value was 2% normal, 97%low and 1%high. The MCHC was 3%normal and 93% low. Conclusion: There is considerable number of donors with haemoglobin concentrations lower than normal as well as lower red blood cells indices. Thus full blood count should be incorporated in evaluating blood donors to insure both good quality of blood and safety of the donors.
