▲Free versus total PSA. The amount of PSA in the blood that is “free” (not bound to other proteins) divided by the total amount of PSA (free plus bound) isdenotedas the proportion of free PSA. Some evidence ...
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...
Free PSA is a newer evaluation for prostate health. This test is used to measure the percentage of free PSA relative to the total amount. Although not used as an initial screening test, a lower percentage of free PSA might mean your doctor needs to do a further testing on the ...
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...

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...
Also Known As: Prostate Blood Test, Free PSA, Total PSA Board Approved Medically Reviewed by Thomas Kampfrath, PhD, DABCC, FAACC Test Quick Guide Prostate specific antigen (PSA) is a type of protein produced by cells in the prostate. The prostate is a small reproductive gland that helps ...
To explore if there is a long‐term association between baseline prostate﹕pecific antigen (PSA), including free/total PSA ratio and long‐term (30 years) risk for prostate cancer death. In all, 1782 men were screened for prostate cancer through PSA analysis. Some years later, frozen plasma...
