CD8 (Suppressor T Cell Marker)
Measures CD8 T cells in blood to assess cellular immunity and monitor infections, immune disorders, and treatment response.
What is a CD8 (Suppressor T Cell Marker) Test?
The CD8 (Suppressor T Cell Marker) test measures the number and percentage of CD8-positive T lymphocytes in a blood sample. CD8 cells are white blood cells that kill virus-infected cells and some cancer cells. They also help control and balance immune responses. Measuring CD8 gives a picture of cellular immunity and immune balance. Abnormal CD8 counts or a changed CD4/CD8 ratio can suggest HIV, chronic viral infections, autoimmune disease, cancer, or immune deficiency. The test is done by flow cytometry as part of lymphocyte subset testing. Results help doctors diagnose, stage, and monitor illness and guide treatment or transplant care. Results are reported as absolute counts and as a percentage of total lymphocytes. Your doctor interprets values alongside other tests and symptoms.
CD8 (Suppressor T Cell Marker) Test Preparation
No special preparation is required.

Why Take a CD8 (Suppressor T Cell Marker) Test?
CD8 (Suppressor T Cell Marker) is usually included in a lymphocyte subset panel and flow cytometry studies. Doctors may order it when a patient has recurrent infections, unexplained fevers, swollen lymph nodes, suspected HIV, or when monitoring cancer, transplant status, or immunotherapy. Abnormal results can be caused by infections, primary or secondary immunodeficiency, autoimmune disease, cancer, or medications such as steroids and chemotherapy. A family history of immune disorders may prompt testing.
