WebA laboratory test that measures the number of CD4 T lymphocytes (CD4 cells) in a sample of blood. In people with HIV, the CD4 count is the most important laboratory indicator of immune function and the strongest predictor of HIV progression. The CD4 count is also used to monitor a person’s response to antiretroviral therapy (ART). WebCD4 T cells are selectively targeted and infected by HIV. HIV proliferates rapidly during acute infection leading to high levels of viremia and rapid impairment and death of CD4 T cells. CD4 T cells are white blood cells called helper T lymphocytes or helper T cells that express cluster determinant 4 (CD4) molecules or markers on their surfaces. display j5 j500
