dc.description.abstractIntroduction and aims: Immunophenotyping by flow cytometry is the most advance and accurate technique for differentiation between lymphocyte sub populations of B and T cells. This descriptive cross-sectional study was performed to establish the normal reference ranges for several lymphocyte sub-populations of healthy adult Sudanese: (CD3, CD4, CD8 and CD19). Materials and Methods: Peripheral blood samples (n = 100) were collected from healthy adult Sudanese from Khartoum State, Sudan. Their mean age was (31± 13) years ranged from (18 to 80) years, and their sex ratio male to females was (1:1). The hematological parameters of them were analyzed by hematology analyzer (Sysmex). The flow cytometry was used to determine percentages and absolute count (cell/μl) of CD3, CD4, CD8 T cells and CD19 B cell. SPSS version 16 was used for statistical analysis. Results: The percentages and mean absolute count (cell/μl) of lymphocytes and lymphocyte sub-populations were obtained as follows: lymphocytes (35.8% ± 7.3 ; 2120.1 ± 652), CD3 (58.9% ± 14.7 ; 1242 ± 481), CD4 (35.9 % ± 20.1% ; 761 ± 315), CD8 ( 18.1% ± 11.1% ; 425 ± 195), CD19 (9.8% ± 5.4%; 214 ± 141). The CD4/CD8 ratio was found to be (1.98 ± 0.85). Conclusion: there was no significant difference according to sex and age in different CD values obtained.
