Age-adjusted CD4+ lymphocyte parameters in healthy children at risk for infection with the human immunodeficiency virus. The Military Pediatric HIV Consortium.
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-adjusted CD4+ lymphocyte parameters. We identified a threshold of approximately 30% CD4+ lymphocytes which corresponded to a 5th percentile for all ages. It is important that no significant differences in absolute CD4+ lymphocyte counts on the basis of ethnic group were found.
