Background:
Laboratory reference intervals are important for both clinical orientations and therapeutic decisions. In Morocco, no reference ranges are available for local population. The ranges commonly used in clinical laboratories and by physicians are those of Caucasian population. We have decided that it is relevant to undertake an epidemiological investigation on local adult healthy population, with the aim of establishing hematology reference intervals in Moroccan population.
Methods:
Blood samples were taken from healthy adult volunteers of the regional transfusion center and measured on a Sysmex XE-2100 analyzer. We have grouped our data samples with regard to gender and retained donors aged between 18 and 45 years old according to ICSH guidelines 1982. Leucocyte, erythrocyte, and platelet parameters were analyzed. For any sample flagged by the automate or thrombopenia with platelets < 100000/microL, a systematic smear was done and checked.
Results:
A significant difference between male and female was found with regard to the values for leucocyte, erythrocyte, and platelet parameters as well as for hemoglobin and hematocrit. These data were compared to normal values reported for Arabic, Caucasian, and African population.
Conclusions:
As part of this study, we have given a descriptive approach of normal blood cell count and its peculiarities in North African Arabian and Berber population not explored until now. We have established similarities and differences between our population and other African, Arab, and Caucasian populations.
