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...
游离PSA/总PSA比值(f/tPSA) 1. Objective To study the early diagnostic value of prostate-specific antigen(PSA),density of PSA(PSAD),free/total prostate-specific antigen ratio(f/tPSA) for prostate cancer. 目的探讨前列腺特异性抗原(PSA)、PSA密度(PSAD)、游离PSA/总PSA比值(f/tPSA)在诊断早期前...

To evaluate the usefulness of measuring the free/total prostate-specific antigen (PSA) ratio (%fPSA) in men with initial PSA levels of 4.1 to 10.0 ng/mL as a predictor of the future risk of developing prostate cancer. Between 1989 and 2001, 201 subjects with an initial PSA level of 4.1...
F-PSA and t-PSA were determined in serum samples of 149 patients (45 with prostate cancer, 50 with benign prostate hyperplasia, 54 healthy controls) using the IMMULITE test. According to the IMMULITE test results, median values for t-PSA (f-PSA) were 1.59 (0.29) 渭g/l in healthy men,...
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.
To ascertain when the serum determination of the free prostate-specific antigen (PSA)/total PSA (fPSA/tPSA) ratio is clinically useful, and whether the identification of PSA or prostate-specific membrane antigen (PSM) mRNA in circulating cells has diagnostic advantages over the determination of ...
To evaluate the value of free PSA/total PSA ratio (fPSA/tPSA) to boost total PSA (tPSA) specificity in the diagnosis of prostate cancer in a series of symptomatic patients.Prospective study on 334 patients presenting symptoms compatible with PBH and tPSA (ProStatus, Wallace Oy, Turku, Finla...
