[Hemogram profile and interest of pre-donation hemoglobin measurement in blood donors in the northwest region of Morocco].

Background: Blood donation in Morocco and more particularly in the northwest region is carried out without prior determination of the pre-donation hemoglobin. In addition, we note the lack of scientific research that reports data on the red blood cells, leukocytes and platelet lines in donated blood at the regional or even national level.

Aims: To study hemogram profile in blood donors taken from the Northwest region of Morocco in order to provide decision makers of the National Center of Blood Transfusion and Hematology with valid scientific arguments to complete the criteria to donate whole blood, by the hemogram.

Methods: Prospective study, conducted in 15797 volunteer blood donors (BD) aged between 18 and 60 years, collected during mobile or fixed collections carried out by the Regional Blood Transfusion Center of Tangier and Tetouan from November 2014 to May 2016. The hemogram was performed using a Sysmex KX21N and the analysis of the data was done by the software SPSS 20.0.

Results: According to the World Health Organization, anemia corresponds to a hemoglobin level less than 12g/dL in women and less than 13g/dL in men. We found that 14.5 % of women (n=1054) and 3.0 % of men (n=245) were anemic and anemia was hypochromic microcytic in 58,66 % of these BD. Analysis of the white line showed leucopenia in 2.05 % of BD and 807 cases of leukocytosis (5.27 % of BD). Platelet study showed thrombocytopenia in 3.97 % of BD and thrombocytosis in 151BD (0.99 % of cases).

Conclusion: This study shows the interest of systematic pre-donation hemoglobin measurement and periodic realization of the hemogram among BD in the Northwest region of Morocco.
