PSA levels are measured in nanograms per milliliter (ng/mL) of blood. While there’s no universal cutoff, a PSA level above 4.0 ng/mL is generally considered elevated. However, what's normal can vary by age:
Age Group |
Typical PSA Range |
40–49 years |
0.0 – 2.5 ng/mL |
50–59 years |
0.0 – 3.5 ng/mL |
60–69 years |
0.0 – 4.5 ng/mL |
70–79 years |
0.0 – 6.5 ng/mL |
That means a PSA of 5.0 might be concerning in a 50-year-old, but not unusual for someone in their 70s.
Not always. While a high PSA can be a warning sign of prostate cancer, there are many non-cancerous causes of elevated PSA, including:
That’s why one elevated PSA test is not enough to make a diagnosis.
If your PSA level is above the normal range for your age, don’t panic—but do follow up. Dr. Samadi typically recommends the following next steps:
A second test helps rule out temporary changes caused by infection or activity. Testing again in a few weeks may show your PSA returning to normal.
These measurements look at how quickly your PSA is rising and how it relates to your prostate size. Rapid changes or a high PSA relative to gland size may require further investigation.
This simple in-office exam checks for physical abnormalities in the prostate.
If PSA remains high or suspicious, Dr. Samadi may order a prostate MRI or recommend a prostate biopsy to determine if cancer is present.
You should seek immediate follow-up if:
With decades of experience in urology and prostate cancer treatment, Dr. Samadi takes a personalized, evidence-based approach. He doesn’t rely on PSA alone—instead, he looks at your full health picture, including age, symptoms, and PSA trends over time.
