Indicators
A protein complex comprised of one T-cell surface glycoprotein CD3 delta chain (CD3D), one T-cell surface glycoprotein CD3 gamma chain (CD3G) and two T-cell surface glycoprotein CD3 epsilon chains (CD3E). CD3D, CD3G and CD3E are transmembrane proteins with one extracellular immunoglobulin domain and one intracellular ITAM domain. The CD3 complex is a T-cell co-receptor that noncovalently associates with either the disulfide bound heterodimeric alpha/beta T-cell receptor (TCR) or gamma/delta TCR and two copies of the accessory protein, T-cell surface glycoprotein CD3 zeta chain (CD247), which is a transmembrane protein with three ITAM domains. The TCR moiety of the TCR-CD3 complex binds to MHC and processed antigens on antigen presenting cells, which triggers phosphorylation of and cellular propagation of the signal by CD247 and the CD3 complex.

Tests
A CD4 count is a blood test that measures the number of CD4 cells in a sample of your blood. 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.
