TNF Alpha (Tumour Necrosis Factor)

Understanding TNF Alpha (Tumour Necrosis Factor)

TNF-α (tumor necrosis factor alpha) is a protein made by the immune cells (white blood cells), especially macrophages and T-cells, when the body encounters infection, injury, or an attack by harmful substances. This chemical messenger signals other immune cells to respond and protect the body. This response is helpful during infections. The production of too much TNF-α can cause long-term inflammation in the body, as seen in conditions like rheumatoid arthritis (RA) or inflammatory bowel disease (IBD)....

What does TNF Alpha (Tumour Necrosis Factor) measure?

The TNF Alpha (Tumour Necrosis Factor) test is a blood test that measures the level of TNF-α, a chemical messenger, produced by the immune system. It helps find out if there is inflammation in the body. It is often used to assess autoimmune disorders, long-term inflammation, or infections.
