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 pr...
Objectives:To explore if there is a long-term association between baseline prostate-specific antigen (PSA), including free/total PSA ratio and long-term (30-year) risk for prostate cancer death. Subjects and methods:In all, 1782 men were screened for prostate cancer through PSA analysis. Some...
Carriers of this SNP allele have reduced serum total PSA and a higher free/total PSA ratio that could contribute to late biopsy decisions and delay in diagnosis. Our results provide a molecular explanation for the prominent 19q13.3 KLK locus, rs17632542 SNP, association with a spectrum of ...

Clinical impact of inter-method bias of prostate specific antigen assays Study of a coefficient of correction for the ratio between free-PSA and total-PSA To obtain a correction coefficient for the conversion of the fPSA/tPSA ratio between methods, considering Roche as the reference test, we fir...
It has been suggested that patients with PSA level above 4 ng/ml should be suspect and prostate cancer needs to be ruled out by additional tests including quantitative PSA, Free-PSA vs total PSA and biopsy when deemed necessary by the physician. PERFORMANCE CHARACTERISTICS The Test was compared...

当诊断敏感度为100%时,在PSA 4～10,10～20μg/L水平,PSAD特异度分别为5.0%和2.1%,可分别避免不必要前列腺穿刺4.9%和2.4%.结论在PSA 4～20μg/L水平上,PSAD和F/T对预测是否行前列腺穿刺有帮助,在诊断敏感度和特异度上,PSAD优于F/T.%Objective To evaluate PSA density (PSAD)and free PSA ...
Thus, the main aim was to assess the outcome after PSMA- PET/CT-based sRT in terms of biochemical recurrence-free survival (BRFS). In addition, univariate and multivariate Cox regression analyses have been used to assess the impact of several risk factors on PSA relapse. Third, recurrence ...
