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
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
Free PSA and Prostate Cancer: What You Should Know - Healthline A PSA test measures your total PSA, meaning both your bound and free Free PSA test purpose The free PSA test is sometimes given instead of a biopsy if your PSA levels are slightly elevated
What Causes Low Free PSA Levels? - WebMD The chances that a needle biopsy will turn up prostate cancer varies by your free PSA concentration and your age: Concentration of more than 25%: About 1 in 10 men ages 50 to 59 will have cancer
Benefits of PSA Free and Total Test vs. PSA Total Test Alone Case Study: Interpreting PSA Free and Total Test Levels in Three Different Scenarios This case study explores the PSA test results of three men, analyzing their total PSA, free PSA, and % free PSA to provide insights into their potential prostate health statuses Case 1: John PSA, Total: 2 4 ng mL; PSA, Free: 0 5 ng mL; PSA, % Free: 21%
Interpreting Prostate Cancer Test Results: A Guide 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 For instance, a reading of 5 ng mL may be concerning in a younger or mid-aged man, but for a healthy 75-year-old, watchful waiting or repeat tests might suffice
What is the difference between PSA and free PSA? Men with a total PSA in the same range and a free PSA below 10% need to have a biopsy More likely than not, they have prostate cancer In some cases, men with a "normal" PSA actually have cancer, but that low PSA doesn't prompt a biopsy A low PSA and a low percentage of free PSA, however, probably would
