ABSTRACT
BACKGROUND: A complete blood count (CBC) analysis is one of the most common conventional blood tests that physicians frequently prescribe. THE OBJECTIVE: of this study was to determine the reference intervals (RIs) of CBC parameters in the population of healthy adults living in the western Sudan region. METHODS: A cross-sectional study of healthy people residing in the western area of Sudan was carried out. We assessed the CBC RIs in samples taken from 153 individuals using an automated haematology analyser (Sysmex KX-21) and a modified Box-Cox transformation procedure to transform the data into a Gaussian distribution after eliminating outliers using the Dixon method. IBM SPSS Statistics version 25 was used to analyse the data, and t tests were employed to examine variations in the mean CBC parameters according to sex and age. P was considered significant at ≤ 0.05. RESULTS: Beyond all the other measured values, the only CBC parameters that significantly differed between the sexes were haemoglobin (HGB) and white blood cell (WBC) counts. Women were found to experience more WBC counts than men did. However, they have less HGB RIs.The male participants in our study exhibited lower WBC count RIs, a significantly lower limit, and a greater upper limit of platelet RIs than did the individuals from other nations. CONCLUSIONS: Compared with males, females had higher platelet and WBC counts and lower HGB.
