ABSTRACT:
To detect Platelets count in apparently healthy male donors, to establish safety for both donors and recipient and
also to transfuse safe blood and blood products. To perform platelets count for donors using automated machine
(Blood cell counter). Venous blood samples were taken from 500 apparently healthy males donors and the platelets
count was measured using an automated cell counter (sysmex KN21), accompanied by peripheral blood films were
assessed to detect any abnormalities. The study revealed that the mean values of the platelets counts were 215.15 x
109 /L +/-68.367 with minimum count 9 x 109 /L and maximum 689 x 109 /L and 67donors presented with platelets
count less than 150 which comprise 13.4 % of the cases, may be due to asymptomatic parasitism (e.g. malaria), no
prominent aggregation or giant forms detected in all cases of thrombocytopenia. Thrombocytosis occurred in
7donors with platelet count more than 400 (1.4% of cases) accompanied by low MCV and low MCH (suggestive of
iron deficiency) which the one of causes of thrombocytosis. The study revealed thata significant number of donors
with low & high platelets count
Key words: Platelets, Thrombocytosis, Thrombocytopenia
