  • a Results are expressed as the mean ± standard error of the mean. Percentile P25 and P75 values for healthy adults (as absolute counts and percentages, respectively) were as follows: for leukocytes, 3.6 to 10.0; for granulocytes, 1.4 to 6.5 and 42.2 to 75.2; for CD4 cells, 700 to 1,100 and 38 to 46; for CD8 cells, 500 to 900 and 31 to 40; for CD4:CD8, 1.0 to 1.5.
