What does this test CD4 & CD8 By Flowcytometry Test identify?

Test CD4 & CD8 By Flowcytometry Test

This test identifies the levels of CD4 and CD8 T-cells in the blood using flow cytometry. CD4 T-cells are a type of white blood cell that helps to coordinate the immune response, while CD8 T-cells are responsible for killing infected cells. By measuring the levels of these cells, healthcare providers can assess the functioning of the immune system and monitor the progression of certain diseases, such as HIV/AIDS and autoimmune disorders.

Why is this test CD4 & CD8 By Flowcytometry Test taken?

Test: CD4 & CD8 By Flowcytometry

CD4 and CD8 are types of T-lymphocytes, or T cells, which are white blood cells that play a crucial role in the immune system. This test is taken to measure the number of CD4 and CD8 T cells in the blood, as well as the ratio between the two. This information is important in assessing the status of the immune system, particularly in individuals with HIV/AIDS or other immune system disorders.

CD4 cells are also known as T-helper cells and are primarily responsible for coordinating the immune response. A decrease in CD4 cells can indicate a weakened immune system, making the individual more susceptible to infections.

CD8 cells, on the other hand, are cytotoxic T cells that directly attack and destroy infected or abnormal cells. An increase in CD8 cells may indicate an active immune response to an infection or other disease.

Flow cytometry is a technique used to analyze and quantify cells based on their physical and chemical properties. By measuring CD4 and CD8 T cells using flow cytometry, healthcare providers can better understand the immune status of an individual and make informed decisions regarding treatment and management.
