METHOD OF ANALYZING NON-COMPLEXED FORMS OF PROSTATE SPECIFIC ANTIGEN IN A SAMPLE TO IMPROVE PROSTATE CANCER DETECTION

摘要

Chemical examination detection determines that there are prostate cancers to be provided. Test can man group in detection prostate cancer have significantly higher Free PSA and t-PSA. The test can also man group in detect prostate cancer content it is lower, t-PSA in 2 to 4 ranges (that is, reach. An embodiment according to the present invention, test is comprising steps of t-PSA contained in (a) quantitative biological sample determines the sample of the Free PSA of amount from patient (two); With. Calculate the Free PSA and t-PSA of the ratio, (step c) determines the amount of pPSA in the sample, it determines (amount of step d) BPSA in the sample, (5) determine include in the amount and sample of the amount f correlations inPSA of inPSA in sample there are the patients of prostate cancer, by comparing the amount and predetermined value of inPSA, establish the control sample with known cancer and benign disease diagnosis, based on t-PSA it is horizontal all with free PSA.
