PSA Velocity Tracker
Enter your PSA results over time. This tool calculates your velocity (rate of rise), compares it to your age-adjusted normal range, and flags clinically significant trends — the same analysis a urologist performs before deciding whether to investigate further.

What is the clinically significant PSA velocity threshold?
A PSA velocity above 0.75 ng/mL per year is the widely used clinical threshold for concern, established by Carter et al. in the Journal of the National Cancer Institute (2006). However, context matters enormously. A PSA rising from 1.0 to 1.8 (velocity 0.8) in a 45-year-old is a different clinical picture from the same velocity in a 75-year-old with a large prostate on ultrasound. Serial trends over 2+ years are more reliable than velocity calculated from just two readings.
My PSA is rising but still within the “normal” range — should I be worried?
Yes, potentially. A PSA of 3.0 in a 55-year-old is technically within the traditional cutoff of 4.0 — but if it was 1.8 two years ago, the velocity of 0.6/year approaching the threshold warrants monitoring. This is exactly why serial PSA measurements over time are more informative than any single reading. Your urologist should have your previous results at every appointment.

Why does finasteride or dutasteride affect my PSA?
5-alpha reductase inhibitors (finasteride, dutasteride) block the enzyme that converts testosterone to dihydrotestosterone (DHT) inside the prostate. DHT drives PSA production. By blocking DHT, these drugs reduce PSA by approximately 50% over 6–12 months. A man on finasteride with a reported PSA of 2.5 has a “true” corrected PSA of approximately 5.0. Failing to account for this can lead to dangerous under-investigation of a genuinely rising PSA. Always tell your urologist you are taking a 5-ARI. See the full prostate cancer screening age guide →
