The hematological reference values used in Sudan were usually from those of Caucasian populations. It has previously been shown that the white blood cells count in Sudanese is different from international values. The objectives of this study were to establish the reference ranges of platelet count and indices in healthy Sudanese adults. The study included 1076 healthy Sudanese adults from five states and both sexes, with age range of 20 – 60 years. Clinical examination was performed, weight and height were measured, and BMI was calculated. Blood samples were obtained from brachial veins and drawn in EDTA tubes. WBCs and differential count were analyzed using Sysmex KX-21 automated hematology analyzer. SPSS version 25 statistical software was used for data analysis, P value ≤ 0.05 was considered significant and 95% CI was accepted. The mean age of participants was 25.23±9.64 years. The median of platelets count was 280×103/µL with reference range of (124- 465× 103/µL)., for platelet distribution width (PDW) was14.6 ٪ with reference range of (9.1-17.1), and for the mean platelet volume (MPV) was 9.8 and the reference range was (8-13.2FL). Female had a significantly higher platelet count (295× 103/µL) than male (245× 103/µL). The platelets count was significantly higher in Red sea state and small age group (20-29), and also. The Sudanese platelets count is higher than many African Countries but lower than the international reference values, and higher in females than males with regional differences.
