Background: The hemogram is the most frequently prescribed laboratory test. It guides the complementary tests essential to the diagnosis and follow-up of the patient. Hematology reference values can be influenced by several parameters such as environmental and genetic factors, rendering it essential to define reference intervals (RIs) for specific populations. This study aimed to determine RIs from a population of healthy adults in Al Hoceima province by following the procedures recommended by the IFCC-CLSI guidelines in 2008 and comparing them to those of similar studies conducted in various countries.
Methods: We initially recruited 977 healthy adults from 18 to 60 years old including 255 men and 722 women, who presented themselves at the provincial hospital center of Al Hoceima (Morocco) for health checkups from February 2019 to September 2019. The erythrocyte, leukocyte, and platelet parameters were investigated using hematology analyzer ABX Pentra XL80 HORIBA® (HORIBA ABX SAS, Kyoto, Japan).
Results: The results showed that the RIs of the blood count parameters searched were more or less close to the RIs determined in Caucasian populations. Nevertheless, they were low compared to the limits of the RIs published in the literature for certain erythrocyte and platelet parameters. Our RIs were also similar in their majority, except for some parameters, to the RIs published very recently in a study conducted on a Moroccan population in the Tangier-Tetouan region. In addition, our intervals differ in their majority from those published in a study of a Ghanaian population.
Conclusions: The differences reported by this preliminary work reinforce the need to establish hemogram RIs specific to the Moroccan population through more extensive studies carried out in different regions of Morocco. These studies should avoid misdiagnosis and allow physicians to interpret hematological tests more specifically.
