▲4Kscore Test. The 4Kscore test takes into account four different prostate-specific biomarkers, namely, total PSA, free PSA, intact PSA, and human kallikrein 2, as well as the patient’s age, prior biopsy history, ...
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...
Variability of assay methods for total and free PSA after WHO standardization. Tumour Biol. 2014 Mar;35(3):1867- 1873. 33. Boegemann M, Arsov C, Hadaschik B, Herkommer K, Imkamp F, Nofer JR, Gerß J, Albers P, Semjonow A. Discordant prostate specific antigen test results despite ...
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...
Measuring prostate specific antigen (PSA) levels can help detect benign prostate hyperplasia (BPH) and/or prostate cancer. This test also measures the percentage of free prostate specific antigen relative to the total amount; a lower percentage of free PSA may indicate the need for furth...
Serum prostate-specific antigen (PSA) assays differ in calibration and response to different PSA forms. We examined intermethod differences in total PSA (tPSA) and free PSA (fPSA) measurements. We tested 157 samples with tPSA concentrations of 2 to 10 ng/mL (2-10 mug/L) using 6 PSA/fPS...
0-10% Free PSA – 56% Risk for Prostate Cancer Catalona et al.JAMA. 1998; 279:1542. Total PSA Test Method: Roche Chemiluminescent Immunoassay ≤4.000 ng/mL Clinical Significance:In men over 50 years of age with total PSA values between 4.000 and 10.000 ng/mL, the percent (%) free PSA...
Between 4 ng/mL and 10 ng/mL. About 25% of men in this group likely have cancer. Your doctor likely will order a free PSA test. Dangerous. Above 10.0 ng/mL. The odds are better than 1 in 2 that you have prostate cancer. Your doctor likely will recommend a biopsy. If your total...
4Kscore, a test that measures total PSA, percent-free PSA, intact PSA, and a protein called human kallikrein 2 (hK2). This test can help determine your risk of aggressive prostate cancer when considered along with your age, biopsy history, and results from digital rectal exams. ...
