text>Especially in the setting of total prostate-specific antigen (PSA) in the intermediate range of 4-10 ng/ml and a negative digital rectal examination, the use of the free/total (F/T) PSA ratio has proved to be an effective tool in prostate cancer screening. Whole blood should be ...
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...
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...
(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=0.34).Comparing with PSA,PSAD provides better sensitivity and specificity...
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.
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。
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 ...
2) Free to total prostate specific antigen ratio 游离/总前列腺特异抗原 3) fPSA 游离前列腺特异性抗原 1. Objective To study the value of TPSA,fPSAand the ratio offPSA/TPSA in differential diagnosis of prostate cancer(PCa). 目的观察血清总前列腺特异性抗原(TPSA)、游离前列腺特异性抗原(fPSA)及...
Clinical Significance of Free-to-Total Prostate-Specific Antigen (PSA) Ratio in Advanced Prostate Cancer Patients with PSA Less than 0.1 ng/ml after Hormon... We analyzed the pattern of change in the free-to-total prostate-specific antigen (f/t PSA) ratio and the progression to castration-re...
If your total PSA levels are in the borderline area between 4-10 ng/mL, your free PSA ratio can give you a more detailed picture of your cancer risk. The chances that a needle biopsy will turn up prostate cancer varies by your free PSA concentration and your age: Concentration of more ...
