Prostate Specific Antigen (PSA) Free with Total Ratio: This test is used to measure the percentage of free PSA relative to the total amount of PSA in men with serum PSA concentrations.
Free/total PSA ratio seems to be an orientation test: towards benign pathology if upper than 20% (VPN = 70%) and towards cancer if lower than 10% (VPP = 52%). Ratio is little contributive between 10 and 20%.doi:info:doi/10.1016/S0923-2532(02)01228-0J.P. Basuyau...
游离PSA比值(Free PSA Ratio)是一种用于判断前列腺癌风险的指标。它是通过测量血液中的游离前列腺特异性抗原(Free PSA)和总前列腺特异性抗原(Total PSA)的比值来计算得出的。 前列腺特异性抗原(Prostate-Specific Antigen,简称PSA)是一种由前列腺细胞分泌的蛋白质,其主要功能是液化精液,帮助精子在射精时更好地游动...

The ratio of free to total PSA has been used to improve the accuracy of PSA testing for screening for prostate cancer, especially for indeterminate levels (4.1–10 ng/mL). At these levels, if the free to total PSA ratio is low, there is a greater chance that the elevation is due to ...

Clinical impact of inter-method bias of prostate specific antigen assays Study of a coefficient of correction for the ratio between free-PSA and total-PSA To obtain a correction coefficient for the conversion of the fPSA/tPSA ratio between methods, considering Roche as the reference test, we fir...
Preliminary results of clinical evaluation of the free/total prostate-specific antigen ratio in a multicentric study. We used a new immunometric assay of free PSA (FPSA-RIACT, CIS Diagnostici, Italy) which has shown good analytical performance; sample handling and ... R Mione,G Aimo,E Bombar...
