How BPH is diagnosed: testing options for men with enlarged prostate symptoms

Worried about an enlarged prostate? Learn how BPH is diagnosed.

When should you get tested for BPH?

If you're over 40 and experiencing any of the following symptoms of an enlarged prostate, it’s time to talk to your doctor about BPH testing:

• Frequent urination, especially at night (nocturia)

• Difficulty starting urination

• Weak or slow urine stream

• Feeling like you still need to urinate after going

• Dribbling or leaking after urinating

• Urgent or sudden need to urinate

How is BPH diagnosed?

For many men, especially those looking for convenience and privacy, screening for an enlarged prostate (BPH) can begin with simple, non-invasive tests from home:

At-home and virtual testing options:

• PSA (Prostate-Specific Antigen) blood test: measures PSA levels in your blood. Elevated levels may indicate BPH, inflammation, or other prostate issues.

• Urinalysis: analyzes a urine sample to check for signs of infection, blood, or other abnormalities that can mimic BPH symptoms.

These tests are often used to screen for prostate health concerns and determine if further evaluation is needed.

If symptoms persist or additional clarity is needed, your healthcare provider may recommend in-office testing.

In-office diagnostic methods:

• Digital rectal exam (DRE): a physical exam to feel the size and shape of the prostate.

• Urine flow test: measures the speed and strength of your urine stream to check for obstruction.

• Post-void residual test: uses ultrasound to measure how much urine remains in your bladder after urinating.

• Cystoscopy: a camera-based test to view the urethra and bladder directly.

These tests help confirm a BPH diagnosis and rule out other conditions, such as prostate cancer or urinary tract obstruction.

Don’t Ignore the Signs.

BPH is common, especially as men age. If you're noticing changes in how you urinate, schedule a BPH test with your healthcare provider.
