title: [Tissue polypeptide antigen (TPA) in non-neoplastic diseases].
abstract: Radioimmunoassay (TPA Prolifigen RIA) was used to determine the serum concentration of TPA in 333 patients with different kinds of non-tumoral diseases. Amounts higher than 90 U/l, that was taken as the upper normal limit, were observed in 40 per 100 of the cases, being higher than 200 U/l in 10 per 100. The frequency of abnormal amounts of TPA in non-tumoral diseases obliges to eliminate them before making a diagnosis of cancer.
