Nj. Waecker et al., AGE-ADJUSTED CD4-CHILDREN AT RISK FOR INFECTION WITH THE HUMAN-IMMUNODEFICIENCY-VIRUS( LYMPHOCYTE PARAMETERS IN HEALTHY), Clinical infectious diseases, 17(1), 1993, pp. 123-125
Values for CD4+ lymphocytes are reported to vary by age. We evaluated
an ethnically diverse population of healthy children at risk for human
immunodeficiency virus infection to establish normal ranges for age-a
djusted CD4+ lymphocyte parameters. We identified a threshold of appro
ximately 30% CD4+ lymphocytes which corresponded to a 5th percentile f
or all ages. It is important that no significant differences in absolu
te CD4+ lymphocyte counts on the basis of ethnic group were found.
