Comprehensive Immune Profile - CD3/CD4/CD8 Cell Count Test

CD3/CD4/CD8 analysis is a laboratory test used to evaluate the levels of T lymphocytes in the blood, where CD3 is a marker for all T cells, and CD4 and CD8 indicate two different subsets of these cells. CD4+ cells play a vital role in enhancing the immune response, while CD8+ cells are essential for attacking infected cells. This test is mainly used in the diagnosis and monitoring of conditions such as human immunodeficiency virus (HIV) infection and autoimmune diseases, helping physicians assess immune system status and guide necessary treatments. It is an important tool for understanding immune health and improving treatment outcomes.
