Tumor Necrosis Factor-a Blood Test
A Tumor Necrosis Factor-a Blood Test is used to monitor levels of tumor necrosis factor-a.
Description
Tumor Necrosis Factor is a protein made by white blood cells in response to an antigen (a substance that causes the immune system to make a specific immune response) or infection. It may boost a person’s immune response, but may also cause necrosis (cell death) of some types of tumor cells. It can be elevated in chronic infections, certain cancers, and Hepatitis C.
