Discover the role of Prostate Specific Antigen (PSA) % in your health and longevity with Mito Health's advanced biomarker analysis. Our detailed reports cover key biomarkers, providing essential insights to help you make informed decisions for a healthier, longer life.
What is Free Prostate Specific Antigen (PSA) %?
Free Prostate Specific Antigen (PSA) % is the ratio of unbound, or "free," PSA to total PSA in the blood.PSA is a protein produced by the prostate gland, and it exists in two forms in the bloodstream: bound to proteins or in a free, unbound form.Free PSA % is used as a tool to help assess prostate health, particularly when evaluating the risk of prostate cancer in men with moderately elevated PSA levels.
What does it assess?
Free PSA % is primarily used to help distinguish between benign prostatic conditions, such as benign prostatic hyperplasia (BPH), and more concerning conditions like prostate cancer.This ratio can provide additional context alongside total PSA levels, helping clinicians decide if further testing, like a biopsy, is warranted.
How do I optimize my Free Prostate Specific Antigen (PSA) % levels?
Diets rich in antioxidants, such as fruits and vegetables, and low in processed foods, red meat, and dairy, are associated with better prostate health.Foods like tomatoes (high in lycopene), cruciferous vegetables, and healthy fats (like those in fish and olive oil) are beneficial. Regular exercise has been linked to lower PSA levels and improved prostate health. Aim for moderate-intensity exercises, like brisk walking or cycling, several times per week. Supplements such as saw palmetto, lycopene, and green tea extract may help support prostate health.
What do high and low Free Prostate Specific Antigen (PSA) % levels mean?
A higher Free PSA % is typically a reassuring sign, as it often indicates benign prostatic conditions like BPH rather than prostate cancer. Generally, a Free PSA % above 25% suggests a lower risk of prostate cancer, but interpretation depends on other factors and the individual’s total PSA level.A lower Free PSA %, particularly below 10%, is more suggestive of prostate cancer, especially if total PSA levels are elevated.
