Description:
Tumor Necrosis Factor (TNF Alpha) Blood Test (Labcorp)
This test measures the level of Tumor Necrosis Factor Alpha in a blood sample. Tumor Necrosis Factor (TNF) is a protein known as a cytokine that is typically produced by white blood cells as part of the body's response to infection. TNF causes inflammation which is part of the normal process through which the body heals. In people with autoimmune disorders, the immune system mistakenly attacks the body's own cells and tissues. Some types of autoimmune disorders such as rheumatoid arthritis, Crohn's disease, ulcerative colitis, and psoriasis are associated with increased production of TNF. High levels of TNF are also sometimes seen in people with insulin resistance which can lead to type 2 diabetes.
Tumor Necrosis Factor testing is sometimes ordered to aid in diagnosing various autoimmune disorders as well as monitoring a person's response to treatment. For related testing options, please see our Autoimmune Testing Category.
Turnaround for this test is typically 3-7 business days.
