About This Tool

This PSA Method Calculator helps evaluate prostate health by calculating key metrics: PSA density (PSAD) and free PSA percentage. Input your total PSA, free PSA, age, and prostate volume (from ultrasound) to get detailed results with risk interpretation. PSAD is calculated as total PSA divided by prostate volume, while free PSA percentage is (free PSA / total PSA) × 100. The tool provides clear risk categories based on medical guidelines to aid in clinical decision-making.

Frequently Asked Questions

Find Quick Answers

What is PSA density?

PSA density (PSAD) is total PSA divided by prostate volume. It helps differentiate between benign prostate enlargement and prostate cancer, with values above 0.15 ng/mL/cc suggesting higher cancer risk.

What is free PSA percentage?

Free PSA percentage is the ratio of free PSA to total PSA, expressed as a percentage. Lower percentages (typically below 25%) are associated with higher prostate cancer risk.

Where do I get prostate volume?

Prostate volume is usually measured via transrectal ultrasound (TRUS) during a prostate exam. Enter the value in cubic centimeters (cc) as provided by your healthcare provider.
