“…Nevertheless, they were low compared to the limits of the references published in the literature [ 19 ]. Our intervals however, diverge in their majority comparison to intervals published in a study carried out on a Moroccan population of the region of Casablanca (Morocco) [ 20 ]. The results of the studies done on Caucasian populations are very close, although the studied populations and the techniques of measurement are different [ 5 , 21 ].…”

“…In our study, concerning the platelet lineage, the values of the median as well as the reference values of the platelet numeration were higher for women than men. These results are supported by numerous studies concerning the populations of different races [ 16 , 18 , 20 , 23 , 33 ]. This report could be attributed, on the one hand, to a hormonal influence and on the other hand, to higher iron losses in women due to menstruation and pregnancy [ 4 ].…”

“…Our results agree with those of the studies of Swaanenburg (40-400 × 10 6 /L for men versus 40-320 × 10 6 /L for women) and of Rakoto et al (0.23 G/L for men versus 0.18 G/L for women) where higher values of EOS were observed for men [ 21 , 34 ]. These results do not suit to those of El Graoui et al (0.01-1.09 × 10 9 /L for women versus 0-1.0×10 9 /L for men) and Ben Amor et al (0-0.35 ×10 9 /L for women versus 0-0.28 ×10 9 /L for men) where the higher values were found rather in women [ 18 , 20 ].…”

“…This report is true for all ages except for the age group 40-50 years when the median values were equal for both sexes (6.9 ×10 9 /L). Numerous studies made similar observations from different races populations [ 18 , 20 , 21 , 33 , 34 ]. This observation was contributed to specific physiological states (menstrual cycle or pregnancy) which slightly increase leukocytosis [ 22 , 35 ].…”

“…In the study of Rakato et al, the mean of the monocytes was superior in women (0.39 G/L) than in men (0.36 G/L) [ 34 ]. The published reference intervals of monocytes, in a study carried out on an adult Moroccan population of the Casablanca region (Morocco), were identical for both sexes (0.2 -1.1×10 9 /L) [ 20 ]. In our study, concerning the platelet lineage, the values of the median as well as the reference values of the platelet numeration were higher for women than men.…”

IntroductionAmong the most useful biological examinations in common medical practice, blood count is the most prescribed. The reference intervals of the hematological parameters of this examination are of major importance for clinical orientations and therapeutic decisions. In Morocco, the reference values used by the laboratories of medical biology and used by doctors are ones collected from Caucasian and European individuals. These values could be different in the Moroccan population. Besides, reference intervals of the blood count specific to the various Moroccan regions are missing. We decided to determine the reference intervals from a population of healthy adults of the Tangier-Tetouan region by following the procedures recommended by the IFCC-CLSI guidelines in 2008 and comparing them to those of the literature.MethodsBlood samples were taken from 15840 adult volunteers (8402 men from 18 to 55 years old and 7438 women from 18 to 50 years old) from the regional transfusion center of Tangier and Tetouan during a period between November 2014 and May 2016. The complete blood count was measured by the Sysmex KX21N® analyzer. For each sample a systematic blood smear was done to determine the leukocyte differential. The data analysis was made by the software SPSS 20.0 by using percentiles 2.5th and 97.5th.ResultsA significant difference between both sexes was noted (p<0,001) for all the hematological parameters (red blood cells, hematocrit, hemoglobin, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, leukocytes, neutrophils, basophils, eosinophils, monocytes, platelets and mean platelet volume) except for the numeration of lymphocytes (p = 0.552). The values of this study were compared with those reported in Arabic, Caucasian and African populations. Said comparisons showed the existence of significant differences.ConclusionThis study tries to accentuate the necessity of proceeding with the establishment of reference intervals specific to the blood count of the Moroccan population to avoid errors of diagnosis, allow clinicians to interpret with greater specificity the hematological examinations and to improve the quality of medical care distributed to patients.

Introduction Haematological reference values are very important for diagnostic orientation and treatment decision. The aim of this study was to establish haematological reference values for Malian healthy adults. Methods A cross-sectional study including 161 male Malians aged between 19 and 54 years old was performed. Median and reference ranges were calculated for haematological and biochemical parameters. Parametric student's t-test was used to determine any statistically significant differences by age, smoker status, body mass index (BMI) and occupation. Ranges were further compared with those reported for other African, Afro-American and Caucasian populations. Results Increased levels of MCV, MCH, PLT and EOS were found in younger Malians who had abnormal BMI and altered platelets parameters. Notably, significantly lower eosinophil and monocyte counts were observed in Malians compared to Europeans The smoking status did not seem to directly affect RIs. Conclusion This is the first study to determine normal laboratory parameters in Malian adult males. Our results underscore the necessity of establishing region-specific clinical reference ranges that would allow clinicians and practitioners to manage laboratory tests, diagnosis and therapies. These data are useful not only for the management of patients in Mali, but also to support European and American clinicians in the health management of asylum seekers and migrants from Mali.
