Order CD4 Count Test | Lymphocyte Count for HIV & ImmunodeficiencyThe CD4 Count Test evaluates specific white blood cell populations that coordinate the body's immune response. By measuring CD3, CD4, CD8, CD16/56, and CD19 lymphocytes alongside the CD4/CD8 ratio, this lymphocyte subset panel offers a structured view of immune status. It is used chiefly to track immune function in people living with HIV and in other conditions where immunodeficiency is a concern.
About CD4 Count Test | Lymphocyte Count for HIV & Immunodeficiency in Central
A lymphocyte subset panel quantifies the major families of white blood cells that carry out and regulate immune defense.
The panel reports absolute counts and percentages for several lymphocyte markers. CD3 identifies mature T cells, while CD4 marks helper T cells that coordinate much of the immune response. CD8 marks cytotoxic T cells that destroy infected or abnormal cells. CD16/56 identifies natural killer cells, and CD19 identifies B cells responsible for antibody production.
The CD4 count is the central value in HIV monitoring because the virus preferentially infects and depletes CD4 helper T cells. A falling CD4 count signals advancing immune suppression and helps guide clinical decisions about when to begin or adjust treatment. The CD4/CD8 ratio adds context: a declining ratio often reflects immune dysregulation even when total lymphocyte numbers appear normal.
Results are interpreted against the full clinical picture, including symptoms, treatment history, and prior values. A single measurement is less informative than a trend over time, so serial testing is common. Specimen handling and timing can influence counts, and the laboratory's reference ranges should be used when reviewing any individual result.
