HEMATOLOGICAL REFERENCE VALUES FOR HEALTHY ADULTS IN EGYPT

Abstract

Hematological reference values are essential for the interpretation of the Result of laboratory tests and treatment decisions. The full blood count reference intervals in Egypt are generally derived from non-Egyptian subjects. This study aimed to establish hematological reference intervals for healthy adults in Egypt. From January 2018 to January 2020, 5620 volunteers were recruited for this study. A total of 5620 was divided into 1846 (32.8 %) males and 2926 (52.1 %) Females. but 848 (15.1 %) volunteers were excluded because of positive laboratory screening results. Males had higher median of hemoglobin (14 g/dL versus 12.3 g/dL), median of RBC (4.96 × 10 6 / µL versus 4.35 × 10 6 / µL), and hematocrit (41% versus 36.2%) than females. The difference in hemoglobin, RBC, and hematocrit by gender was statistically significantly different (p < 0.05). Males had lower median white blood cell (6.7× 10 3 / µL versus 6.9× 10 3 / µL) and median of Platelets (230 × 10 3 / µL versus 252.5 × 10 3 / µL) than Females (p < 0.05). in comparison to reference values that are commonly used in Egypt, the hemoglobin levels, RBC, and hematocrit from this study were lower.
