This assay is CD4+ lymphocyte subset enumeration using Pan Leukocyte (CD45+) Gating strategy. CD4+ lymphocyte percentages and absolute counts may be used as aid in evaluation of immune competency. Progressive clinical and immunologic deterioration correlates with decreasing CD4+ counts in HIV infections and response to therapy correlates with elevation of CD4+ counts. Reference interval of CD4+ by Pan Leucocyte gating method for persons less than 18 years is not available.
