Reference ranges of lymphocyte subsets in healthy Qatari adults
الملخص
Aim: Determine reference ranges of lymphocyte subsets in healthy Qatari adults.
Patients & Methods: Blood samples (n = 150) were investigated using four colors flow
cytometery. Results: The mean percentage and absolute values of the lymphocyte
subsets were: CD3: 73.6 ± 6.1%; 2,072 ± 644 cells/μl; CD4: 41.1 ± 7.9%; 1,167 ± 396 cells/
μl; CD8: 33.8 ± 7.1%; 967 ± 364 cells/μl; B cells (CD19+): 11.3 ± 3.9%; 318 ± 144 cells/μl
and natural killer (NK) cells (CD16/56+): 16.5 ± 6.3%, 440 ± 401 cells/μl, respectively.
The CD4/CD8 ratio was 1.3 ± 0.5. The ratio, CD3+ and CD4+ percentage and CD4+
cell counts were significantly higher in females; CD8+ and NK cell count and CD8+
percentage were significantly higher in males. The impact of age was less certain.
Conclusion: The reference values of lymphocyte subsets appear to be specific to this
population, demonstrating the importance of establishing local reference ranges.
