Tumor Necrosis Factor-Alpha (TNF)


This blood test measures Tumor Necrosis Factor-alpha, a cytokine (signal protein that facilitates intracellular communication) that promotes the inflammatory response. Tumor Necrosis Factor-alpha is clinically associated with autoimmune disorders such as rheumatoid arthritis, inflammatory bowel disease, psoriasis and refractory asthma. Tumor Necrosis Factor-alpha may be elevated in Alzheimer’s disease and various other autoimmune and infectious diseases.

Test Preparation For Optimal Results:
If possible, have the lab collected early in the morning or shortly after waking. For comparison purposes, have subsequent labs collected close to the same time.
