MICROSCOPIC EXAMINATION OF WHITE BLOOD CELLS WITH DIFFERENTIAL COUNTS IN APPARENTLY HEALTHY SUDANESE POPULATION IN GEZIRA STATE (SUDAN)
Journal Title: World Journal of Pharmaceutical and Medical Research - Year 2017, Vol 3, Issue 1
Abstract
Objective: To examine white blood cells microscopically in apparently healthy male blood donors, to detect the morphological features of white blood cells. To perform differential white blood count. Material and Methods: Venous blood samples were taken from 500 apparently healthy males donors and the white blood count was measured using an automated cell counter (sysmex KN21), accompanied by peripheral blood films were assessed to manual differential count. Results: The study revealed that the mean values of white blood cells were found to be 5.696 +/-1.7989 with minimum count 2.1 x 109 /L and maximum count 14.1 x 109 /L, a considerable numbers of donors were leucopenic,77 cases ranged from 2.1 to 3.9 which represents 15.4% and a few numbers with leucocytosis, 5 cases ranged from 11.1 to 14.1 which represents 1%, dominated by neutrophils which suggestive of pyogenic infection, high eosinophil percentage more than 4% observed in 121 donors (24.2%), the bulk of this eosinophilia probably reflects asymptomatic parasitism (e.g. schistosomiasis). Monocyte percentage more than 8 % observed in 6 donors (1.2%) and high lymphocyte percentage with the reactive forms of lymphocyte also detected most probably due to chronic infection. Conclusion: The study revealed that significant numbers of Sudanese population with low white blood count, low neutrophil count, high lymphocyte and eosinophil count compare with Caucasian.
