Book a Test- CD8

CD8, also known as cluster of differentiation 8, is a protein found on the surface of certain immune cells, called cytotoxic T cells. CD8 cells play a crucial role in the immune system by recognizing and killing infected cells or tumor cells. CD8 cells work by recognizing specific antigens on the surface of infected cells or tumor cells, and then releasing toxic chemicals to kill them. They are an important part of the immune system's defense against viral infections, such as HIV, and cancer. The CD8 count is a blood test that measures the number of CD8 cells in the blood. It is used to monitor the health of individuals with HIV infection and other immunodeficiency disorders. A high CD8 count can indicate a strong immune response, while a low CD8 count can indicate a weakened immune system.
