Complexed PSA.This measures the amount of PSA that is attached to proteins in your blood. It’s not widely used, but it may be done rather than assessing total and percent-free PSA levels. Combination tests.Newly developed tests combine the measurements that you get from different PSA tests....

When the volume of the prostate increases, as when cancer is present, the levels of PSA in the blood also increase. Our work focuses on using PSA levels as a biomarker for the recurrence of prostate cancer in patients that have been previously diagnosed and treated by radiotherapy. We fit ...
complexed PSA (cPSA) fraction is bound to alpha-1-antichymotrypsin with less than 5% bound to other complex ligands (eg, alpha-1-protease inhibitor (157, 166-168)). PSA bound to alpha-2-macroglobulin is not detected by current immunoassays for PSA. Levels of cPSA in blood can be[...
cancer is the most common male cancer and the second leading cause of cancer death in men in the UK. PSA is an enzyme produced by the prostate gland whose purpose is to liquefy semen, and normally, only very small levels of PSA are found in serum. Elevated levels may be found in men...

Historical prostate-specific antigen (PSA)-based screening studies reduced prostate cancer-related deaths but also led to overdiagnosis/overtreatment. Since then, opportunistic PSA testing has increased, and late-stage diagnoses and prostate-cancer relat
The percentage of GFP−/lo LNCaP cells was very close to that of PSA−/lo cells in LNCaP cultures (2.2% ± 1.5%; n = 4). Real-time (qPCR; Figure 1D) and semiquantitative (Figure S3C) RT-PCR revealed lower PSA mRNA levels in GFP−/lo LNCaP cells compared to the corresponding...
Is additional testing necessary in men with prostate-specific antigen levels of 1.0 ng/mL or less in a population-based screening setting? (ERSPC, section Rotterdam). Urology 2005;65(2):343-346. 摘要 目标:目前,全球不同国家正在使用几种前列腺癌筛 查间隔,从 1 年 ~ 4 年不等.最近,有人提议...
The significance of the PSA level should always be assessed in proportion to the size of the prostate. The larger the prostate, the higher the PSA level. Even quite low PSA levels can indicate cancer. The level of free PSA is significant in differential diagnostics when assessing benign and ...
