PSA Testing
A simple blood test that helps us watch your prostate health closely and catch concerns early.
PSA testing measures prostate-specific antigen, a protein made by the prostate, to help detect and monitor concerns with your prostate health. As part of your preventative medicine care in Los Angeles, we use it alongside your history and exam to guide thoughtful, individualized decisions about screening.
How PSA Testing Works
PSA testing is a standard blood test, drawn from a vein in your arm during a quick blood draw. The sample is sent to the lab, which reports the level of PSA circulating in your blood.
We interpret your result in the context of your age, prostate exam, and any prior values, since PSA can rise for benign reasons as well as concerning ones. We often pair PSA with a comprehensive physical examination so the full picture informs next steps.
How to Prepare
For most men no special preparation is required, but a few activities can temporarily raise PSA and are worth avoiding for a couple of days beforehand.
Let us know about any recent symptoms, procedures, or medications before your draw, as these can affect how we interpret your result. We will give you clear, personalized guidance when your test is ordered.
Before Your Test
- Avoid vigorous cycling or strenuous exercise for 48 hours before your draw.
- Abstain from ejaculation for about 48 hours, as it can briefly elevate PSA.
- Mention any recent urinary infection, catheter, or prostate procedure.
- Share a full list of your current medications and supplements.
After Your Test
Results are typically available within a few days, and we will review them with you and explain what they mean for your care. A normal result is reassuring, while a mildly elevated or rising level may simply call for a repeat test over time.
If your PSA warrants closer evaluation, we arrange timely specialist referral and coordination with urology, including Cedars-Sinai coordination when appropriate, so you are never navigating next steps alone.
