“…In the current study, the lower limit of Hb in the female group was lower compared with the Caucasians (France and Canada) (1,35) and also the populations in Oman and Kuwait (3,14). A possible explanation of the Hb difference compared to Caucasians is the prolonged menstrual cycle in Saudi women [median bleeding days were 5 (1-16)] (36).…”

“…The reported hematological parameters RIs in literature differ for populations, for example, Asian Americans and American blacks compared to white Americans ( 4 ), South Indians compared to European ( 5 ) and Africans compared to Western populations ( 30 , 31 ). Few studies recently reported hematological RIs in the Middle Eastern region ( 3 , 7 , 13 , 14 ).…”

“…Most of the literature is based on the RIs established in Western populations (10)(11)(12). Recent studies reported RIs in the Middle East region (3,7,13,14). A few studies from Saudi Arabia were not comprehensive enough due to a small sample size (15), targeted children and adolescents (16), or focused on one region (17).…”

IntroductionHematological parameters are critical in disease diagnosis, management, and monitoring; however, complete blood count (CBC) reference intervals vary across populations. The aim of the current study was to provide the reference ranges of hematological parameters/indices in the healthy adult Saudi population.MethodsA multicenter retrospective cross-sectional study was conducted with a sample of employees who were screened pre-employment from January 2015 to December 2019, at tertiary care hospitals in three regions. Demographic and CBC data were extracted from the electronic health system. The 2.5th and 97.5th percentiles were used to determine the reference intervals.ResultsOf a total of 1,388 participants, 53.82% were male. The majority 96% was less than 40 years old, and 85% were from the Central region. Gender-related differences were observed for the RBC count, Hb, HCT, MCV, MCH, MCHC, and the platelet count. Age-related differences were observed for the RBC, Hb, HCT, and eosinophils. The WBC parameters did not differ by gender or age categories. Region-related differences were observed for the RBC, hemoglobin, HCT, MCV, WBC, and basophils. The platelet count was higher in the female group, the age group 40 years and above, and in the Western region. The prevalence of anemia was high in the female group and the Eastern region. The overall neutropenia rate was 12.8%.ConclusionThe data from this study provide hematological parameter reference ranges for the adult Saudi population by gender, age, and region. Gender and age-related differences were observed for the hematological parameters. Anemia was more frequent in the female group and the Eastern region. Caution must be taken when comparing or interpreting results from different age groups, gender, region of origin, and ethnicity.
