T-cell helper (CD4) subset panel
A CD4 count is a blood test that measures the number of CD4 cells in a sample of your blood. 4 tests in this panel.
CD4 cells are a type of white blood cell that circulates throughout the body in the blood. They're also called CD4 T lymphocytes or "helper T cells." That's because they help fight infection by triggering your immune system to destroy viruses, bacteria, and other germs that may make you sick.
