- PSA, % Free - Lab Results explained | HealthMatters. io
Total PSA gives an overall measure, while free PSA and % free PSA help refine the interpretation: Elevated Total PSA with Low % Free PSA: This combination is more suggestive of prostate cancer For instance, a % free PSA below 10% is associated with a higher risk of prostate cancer
- Prostate-Specific Antigen (PSA), Total and Free, Serum - Mayo . . .
Interpretation When total prostate-specific antigen (PSA) concentration is below 2 0 ng mL, the probability of prostate cancer in asymptomatic men is low, further testing and free PSA may provide little additional information
- Free PSA and Prostate Cancer: What You Should Know - Healthline
A free prostate-specific antigen (free PSA) test is used to confirm test results from a PSA test, which is used to help diagnose prostate cancer Learn more
- What is the difference between PSA and free PSA?
The free-PSA test measures the percentage of unbound PSA; the PSA test measures the total of both free and bound PSA Prostate cancer can raise PSA levels, but so can other conditions These include an enlarged prostate, prostatitis, and advancing age In fact, studies have shown that about 75% of men with an elevated PSA do not have prostate
- What Causes Low Free PSA Levels? - WebMD
A low free PSA level can be a sign that you’re at higher risk for prostate cancer Find out what it is and how it’s measured
- Free PSA: Test, results, and prostate cancer - Medical News Today
A free PSA test measures the level of prostate-specific antigens (PSA) that are not bound to other proteins in the blood This helps diagnose prostate issues
- Free Prostate Specific Antigen (PSA)
For unclear reasons, patients with cancer make less free PSA than patients with benign prostate conditions and the percentage of free PSA can better estimate the likelihood a biopsy will show cancer than the total PSA alone
- Interpreting Prostate Cancer Test Results: A Guide
Free vs Total PSA: Free PSA measures the unbound fraction of the antigen, distinguishing benign from malignant causes A lower free-to-total ratio leans toward cancer suspicion, guiding whether advanced imaging (MRI) or biopsy is justified Interpreting PSA results involves more than raw thresholds
