Abstract
Prostate specific antigen (PSA) is a protein that can form complexes with proteinase inhibitors such as .alpha..sub.1 -antichymotrypsin. The invention is characterized in that the measurement of the ratio of free PSA to PSA bound to proteinase inhibitors (free PSA:PSA-proteinase inhibitor complex) is useful in the diagnosis of patients with prostate cancer.
