Comparisons between the lymphocyte subpopulation counts at different sampling sites.

Lymphocyte subpopulation counts are shown for all comparisons with PResults annotated with ‘*’ are considered significant for the method applied. Sites comparison between sampling sites; ARD average relative difference; PLT platelets; NGC neutrophils; WBC white blood cells; RBC red blood cells; HCT hematocrit; RD radial artery vs. dorsal hand veins; RE radial artery vs. antecubital veins; DE dorsal hand veins vs. antecubital veins.aAfter omission of outliers the P value from the paired t-test was 0.093 with ARD 6.7%. The multivariate analysis showed a P value of 0.014.bAfter omission of outliers the P value from the paired t-test was 0.11 with ARD 3.3%. The multivariate analysis showed a P value of 0.042.
