The Free PSA Test measures the amount of unbound (free) prostate-specific antigen in the blood. PSA is a protein produced by the prostate gland. In the blood, PSA exists in two forms:
• Bound PSA – attached to proteins.
• Free PSA – not attached (free-floating).
This test is usually done alongside total PSA testing to help differentiate between benign prostate conditions (like BPH – Benign Prostatic Hyperplasia) and prostate cancer, especially when total PSA levels are moderately elevated.

    Description

    Why It’s Done
    The Free PSA test is typically recommended to:
    • Evaluate elevated total PSA levels (usually between 4–10 ng/mL).
    • Help differentiate between prostate cancer and non-cancerous prostate enlargement.
    • Support decision-making on whether a prostate biopsy is necessary.
    Lower free PSA percentage may indicate a higher risk of prostate cancer.
    Higher free PSA percentage suggests a lower cancer risk, more likely due to benign conditions.

    Preparation
    • Avoid ejaculation for 24–48 hours before the test (may raise PSA levels).
    • No digital rectal exam (DRE) for 24 hours prior, if possible (can temporarily elevate PSA).
    • Inform your doctor about any medications or supplements, especially:
    o 5-alpha reductase inhibitors (like finasteride)
    o Hormonal treatments
    • Fasting is not required.
    • A blood sample is taken from a vein in your arm.
