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 wall and eventually wind up in...
a number of professional medical organizations began to caution against routine population screening with the PSA test. Most organizations recommend that individuals who are considering PSA screening first discuss the risks and b...
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 ng/ml. An fPSA fraction of more than 20–25% is considered unsuspicious for a prostate...
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 ...
"This results in some men going on to have invasive treatment that they don't need, many years earlier than without screening, and the test is also failing to spot some cancers that do need to be treated. We need to find better ways to spot aggressive prostate cancers, so we can treat...

Prostate Specific Antigen (PSA) test is a blood test useful in screening and diagnosis of prostate cancer or other prostate related disorders. PSA is a chemical made by the prostate gland and is produced by both cancerous and non-cancerous prostate tissues. This test estimates the amount of ...

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 ...
