What does this test CD4 (T Helper Cell) Test Immunohistochemistry identify?

CD4 (T Helper Cell) Test Immunohistochemistry

The CD4 (T Helper Cell) Test Immunohistochemistry is a diagnostic test that identifies the presence of CD4-positive T helper cells in tissue samples. CD4 is a glycoprotein found on the surface of T helper cells, which play a crucial role in the immune response. By identifying the presence of CD4-positive cells in tissue samples, this test can help in the diagnosis of various immune-related disorders, such as HIV/AIDS, autoimmune diseases, and certain types of cancer.

Why is this test CD4 (T Helper Cell) Test Immunohistochemistry taken?

The CD4 (T Helper Cell) Test Immunohistochemistry is taken to measure the number of CD4-positive T cells in a tissue sample. CD4 cells are a type of white blood cell that plays a crucial role in the immune system by helping to coordinate the body's response to infections.

This test is commonly used in the diagnosis and monitoring of diseases that affect the immune system, such as HIV/AIDS. A low CD4 count can indicate a weakened immune system and an increased risk of infections. Conversely, a high CD4 count can suggest an overactive immune response, such as in autoimmune diseases.

Immunohistochemistry is a technique that uses antibodies to detect specific proteins, in this case CD4, in tissue samples. By measuring the presence and quantity of CD4 cells in a tissue sample, healthcare providers can assess the status of a patient's immune system and guide appropriate treatment decisions.
