Tumor necrosis factor (TNF)-alpha is a nonspecific marker associated with an inflammatory response, and is not diagnostic for any specific disease or disease process. Elevated concentrations of TNF-alpha must be interpreted within the clinical context of the patient. Normal concentrations of TNF-alpha do not exclude the possibility of an ongoing inflammatory process.
