What Is the PSA Screening Test? The PSA screening blood test measures the levels of PSA circulating in the blood. Both normal prostate cells and cancer cells make PSA. While prostate cancer cells tend to produce less PSA than normal cells, they allow PSA to more easily pass through the cell...
The home PSA Screening Test offers numerous benefits, including accurate and reliable results from a CLIA-certified lab without the hassle of scheduling an appointment or drawing blood from your arm. The process is quick and virtually painless, making it an excellent option for proactive health moni...

As the proportion of fPSA decreases, the probability of prostate cancer increases (Polascik et al., 1999). The fPSA is used to increase the sensitivity of the PSA screening in the range of 2–4 ng/ml. Furthermore, fPSA improves the specificity of PSA screening in the range of 4–10 n...

Screening for prostate-specific antigen (PSA) significantly cuts the death rate from prostate cancer, so America's medical community should continue to offer the test to appropriate men, but at the same time should work harder to avoid the screen's poten
The ratio of free to total PSA has been used to improve the accuracy of PSA testing for screening for prostate cancer, especially for indeterminate levels (4.1–10 ng/mL). At these levels, if the free to total PSA ratio is low, there is a greater chance that the elevation is due to ...
Objectives: To document the extent of prostate-specific antigen (PSA)-testing in the general population at Getafe (Spain) outside our prostate cancer (PC) screening program, and to check its performance in terms of PC detection. Methods: A total of 5371 PSA-test records (1997–1999) were ...
aIt is prudent to include with the PSA result a reminder that a single screening blood test result should not be used as the sole evidence of the presence or absence of malignant disease. The laboratory report should include the manufacturer of the PSA assay used, draw attention to any ...
