title: The influence of age on peripheral lymphocyte count in men: a cross-sectional and longitudinal study.
abstract: The peripheral lymphocyte count was determined on 436 carefully screened healthy male participants of the Normative Aging Study on three successive determinations over a ten year period. Cross-sectional analysis revealed no significant differences in absolute lymphocyte count between the age groups 23 to 44, 45 to 54, and 55+ years. Longitudinal analysis also showed no significant change in absolute lymphocyte count over the study period. These results indicate that absolute lymphocyte count in healthy men does not change with age.
