According to the method of the invention, immunoassays are applied to measure free PSA as well as a proteinase inhibitor complex. Free PSA and PSA complex are according to the invention measured by a non-competitive immunoassay employing at least two different monoclonal antibodies. The invention is further characterized by that the PSA proteinase inhibitor complex of interest is formed either with .alpha..sub.1 -antichymotrypsin, .alpha..sub.1 -protease inhibitor (API) or .alpha..sub.2 -macroglobulin. Moreover, the invention is characterized by that free PSA, the PSA-proteinase inhibitor complex and their ratio are applied in the diagnosis of patients with prostate cancer.
