WebJun 10, 2024 · CD4 cells (also known as CD4+ T cells) are white blood cells that fight infection. CD4 cell count is an indicator of immune function and disease progression and one of the key determinants for the need of opportunistic infection (OI) prophylaxis. CD4 cell counts are obtained from bloodwork as part of laboratory monitoring for HIV infection. WebThe level of CD4+ T-lymphocytes is known as the CD4 cell count or just the CD4 count. It is an indication of the strength of the body’s immune defenses. A normal CD4 count is between 500 to 1500 cells per cubic millimeter (mm3). It is sometimes designated as a percentage. A CD4 percentage of greater than 29% roughly indicates a CD4 count of ...

CD4 Cell Count and the Risk of AIDS or Death in HIV-Infected
WebThe CD4/CD8 ratio is calculated by dividing the CD4 cell count by the CD8 cell count. For example a ratio of 2 would indicate that there are 2 CD4 cells for every 1 CD8 cell. A normal ratio is between 1 and 3. HIV-negative people generally have a greater number of CD4 cells than they have of CD8 cells. As people get older, the immune system's ... WebPoor CD4 cell count response was strongly associated with virus-related NADC incidence, suggesting an important role for T-cell mediated immunity in pathogenesis. Lower CD4 cell count proximal to cancer diagnosis may be a result of subclinical cancer. Intensified cancer screening should be considered for patients on ART with low CD4 cell counts.
