The 2014 recommendations of the International Antiviral Society – US Panel state that measurement of CD4 count is optional among patients with suppressed viral loads for >2 years and CD4 counts >500/µL. CD4 measurement in these patients is of low-value and may create unnecessary patient concern in response to normal variation of CD4 counts. In prospective studies of patients who have responded to antiretroviral therapy with HIV-1 RNA suppression and rises in CD4 cell count >200 cells/μL, there was little clinical benefit from continued routine measurement of CD4 counts.
