Service Providers for Free PSA/ PSA Ratio
The Free PSA/PSA Ratio is a diagnostic test used to evaluate prostate health and assess the risk of prostate cancer. Prostate-specific antigen (PSA) exists in two forms in the blood: free (unbound) PSA and PSA bound to proteins. The ratio of free PSA to total PSA is calculated as a percentage. A lower ratio (e.g., below 10%) may indicate a higher risk of prostate cancer, whereas a higher ratio suggests benign prostate conditions, like benign prostatic hyperplasia (BPH). Factors such as recent prostate manipulation, infections, or age can influence results. This test is typically used alongside other assessments like biopsies for a more accurate diagnosis.
