PSA Free & Total Blood Test

PSA Free/Total

This enhanced PSA panel measures both total PSA and free PSA, calculating the free PSA percentage. This ratio helps distinguish prostate cancer from benign prostatic hyperplasia when total PSA is elevated.

The Free & Total PSA test provides more information than total PSA alone. PSA circulates in two forms: "free" (unbound) and "complexed" (bound to proteins). The percentage of free PSA can help distinguish between prostate cancer and benign conditions when total PSA is elevated (typically 4-10 ng/mL—the "gray zone").

Prostate cancer tends to produce more complexed PSA, resulting in a lower percentage of free PSA. Benign prostatic hyperplasia (BPH) typically has a higher percentage of free PSA. This distinction can help avoid unnecessary biopsies in men with elevated total PSA from benign causes.

This test is most useful when total PSA is in the 4-10 ng/mL range, where the free PSA ratio provides the most diagnostic value.

What This Test Measures

This test measures: (1) Total PSA in ng/mL, (2) Free PSA in ng/mL, and (3) Free PSA percentage (free PSA ÷ total PSA × 100). All three values are important for interpretation.

Who Should Consider This Test

Men with elevated total PSA (especially 4-10 ng/mL), those wanting more detailed prostate assessment, men trying to avoid unnecessary biopsy, anyone with borderline PSA results, and those monitoring known prostate conditions.

When to Get Tested

No fasting required. Same precautions as total PSA: avoid ejaculation for 24-48 hours before testing. Wait 6 weeks after any prostate procedures or infections.

Understanding Your Results

The free PSA ratio interpretation: >25% free PSA suggests BPH (low cancer risk), 10-25% is intermediate, <10% suggests higher cancer risk. However, these are guidelines—clinical context matters. A low percentage doesn't confirm cancer, and a high percentage doesn't exclude it.

What to Expect

After placing your order, you'll receive an email from Rupa Health (our lab order partner) within 24 business hours to sign a consent form and schedule your blood draw at a Quest Diagnostics location.

The blood draw typically takes just a few minutes. Results are usually available within 1-2 business days and will appear in your secure Justlabs dashboard.
