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.
(2006). Free/total PSA ratio can help in the prediction of high gleason score prostate cancer in men with total serum prostate specific antigen (PSA) of 3-10 ng/ml. Int Urol Nephrol 38:553-557.Elabbady AA, Khedr MM. Free/total PSA ratio can help in the pre- diction of high ...
目的通过对前列腺特异抗原(PSA)密度(PSAD),总PSA(tPSA),游离PSA/总PSA(fPSA/tPSA)的ROC曲线分析,进一步探讨三者在前列腺癌(PCa)诊断灰色带中的临床诊断价值。
PSA比值（PSA ratio）是一项用来评估前列腺健康的指标。这项测试通过比较前列腺特异性抗原（PSA）中前列腺特异性抗原-2（PSA-2）的含量来确定，因此被称为PSA比值。PSA是前列腺细胞产生的一种蛋白质，是前列腺癌的一个标志物。PSA比值的正常值在0.1-0.25之间，如果PSA比值高于这个范围，则需要进一步...
根据筛查切点值,将总人群和不同年龄亚组人群分为tPSA(或fPSA/tPSA)阳性和阴性人群,并进一步采用Cox回归分析评估阳性人群相比阴性人群发生前列腺癌的相对风险,以风险比(hazard ratio,HR)和95%CI衡量相对风险的大小。使用2 000次Bootstra...
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)在诊断早期前列腺癌(PCa)中的价值。

我体检PSA-Ratio0.21偏低是什么, 想得到怎样的帮助: 解答是什么问题温馨提示:因无法面诊,医生建议仅供参考 谷印亮 医师 中医科 免费咨询 一级甲等 河北省邢台市威县贺钊卫生院 问题分析:你好,这偏低影响不大,如果增高,这可能是前列腺炎或者前列腺癌等引起的,请问目前有什么不适的感觉,说一下主要的症状,如果没...
Results PSA,PSAD of PCa were significantly higher than that of BPH (PSA:46.3±33.8μg/Lvs7.04±6.91 μg/L,P=0.000021;PSAD:1.43±1.21μg.L-1.ml-1vs0.14±0.15ng.ml-1.ml-1,P=0.000055).There's no difference of F/TPSA ratio between BPH and PCa cases (0.22±0.18vs 0.18±0.11,P=...
