Absolute T4 count AIDS The number of 'helper' T cells/mm3 in Pts with HIV, which declines as infection progresses; the absolute CD4 count was the standard lab parameter used to monitor the immune suppression in persons with HIV; HIV RNA levels are more valid markers of immune responsiveness, and are the gold standard for Pts with AIDS/HIV infection
