Abstract

A single-step qualitative rapid test for the determination of prostate-specific antigen (PSA) in samples of human blood serum by immunochromatography using a complex of colloidal gold with monoclonal antibodies to PSA as the detection agent was developed. The determination limit for PSA in serum blood samples is 10 ng/ml; the analysis time, 15-25 min; the sensitivity of the method, 100%; and its specificity, 92.5%.
