About CD4 Count Test | Lymphocyte Count for HIV & Immunodeficiency in Irvine
CD4 cells, also called T-helper cells, coordinate much of the immune response. Because HIV targets these cells, tracking their numbers gives a direct view of how the virus is affecting immune function over time.
A lymphocyte subset panel typically reports CD3, CD4, and CD8 counts along with the CD4/CD8 ratio, plus CD16/56 natural killer cells and CD19 B cells. Each marker reflects a different arm of the immune system, so the panel provides a broad picture rather than a single number.
CD4 results are interpreted alongside the CD4 percentage and the CD4/CD8 ratio. A falling CD4 count or a declining percentage can indicate advancing immune suppression, while stable values suggest the immune system is holding steady.
This test is used for monitoring rather than diagnosis. It helps clinicians follow the course of HIV infection, evaluate immunodeficiency, and track response to treatment, but it does not by itself confirm or exclude any condition.
