What's this test for?

This test is ideal if you're trying to understand your prostate cancer risk more clearly, especially if you've had a borderline or unclear PSA result in the past. It helps if you have a family history of prostate cancer or are looking for a more precise way to decide whether further testing, like a biopsy, is really necessary. Instead of just measuring how much PSA is in your blood, it looks at the structure of the PSA protein itself to better tell apart high-grade cancer from low-grade or benign conditions.

What's included in this test?

This test looks at the different structural forms, or isoforms, of the PSA protein in your blood rather than just the total amount. Because certain structural patterns are more closely linked to aggressive prostate cancer, this approach gives a clearer picture than a standard PSA number alone. It's designed to help separate cases that need closer attention from those that are likely low-risk or benign.

What happens after I get my results?

Your results will show up in your account with a clear explanation of what your score means and how it compares to the normal range. Depending on where you land, the report will outline sensible next steps, such as continuing routine monitoring, considering further evaluation, or simply rechecking down the road. You can download a standard lab report straight from your account at any time, and if you retest in the future, the trends feature lets you track changes in your results over time.

How should I naturally support prostate health?
Eating more tomatoes, cruciferous vegetables like broccoli, and foods rich in omega-3 fats has been linked to better prostate health. Staying active with regular exercise and maintaining a healthy weight can also help lower your overall risk. Cutting back on red meat, processed foods, and excess dairy may be helpful too, though these habits work best alongside regular testing rather than as a replacement for it.
When will I get my results?
Results are typically ready within about 7 days after your sample is collected at the lab. You'll get a notification once your report is available, and you can log into your account anytime to view it. If your results are delayed for any reason, you'll be able to see an updated status in your account.
Who should consider this test?
Men who have had an elevated or borderline PSA test and want more clarity before deciding on next steps are good candidates for this test. It's also worth considering if you have a family history of prostate cancer or want a more detailed look at your risk without jumping straight to invasive procedures. Talk through your personal risk factors and history when deciding if this test makes sense for you.
What symptoms indicate I may need this test?
Prostate issues often don't cause obvious symptoms early on, which is why testing matters. That said, things like frequent urination, difficulty starting or stopping urination, a weak urine stream, or discomfort in the pelvic area can sometimes point to prostate changes worth investigating. If you've noticed any of these along with a prior elevated PSA, this test can help clarify what's going on.
What does a high IsoPSA result mean?
A higher IsoPSA score suggests a greater likelihood that structural changes in your PSA protein are linked to more aggressive, high-grade prostate cancer. This doesn't mean cancer is confirmed, but it does suggest that further evaluation is a reasonable next step. Bring this result into your overall health picture along with any other symptoms or family history you have.
What does a low IsoPSA result mean?
A lower score suggests your PSA structural pattern looks more like what's seen in low-grade or benign prostate conditions rather than aggressive cancer. This is generally reassuring, but it doesn't rule out prostate issues entirely, so continuing with routine monitoring is still a good idea. Maintaining healthy habits and rechecking periodically is a sensible approach after a low result.
How often should I retest?
How often you retest usually depends on your prior results, age, and family history, so there's no single answer for everyone. Many men who've had a borderline or high result choose to retest annually or as recommended based on their specific score. Keeping a consistent testing schedule makes it easier to spot meaningful changes over time using the trends feature in your account.

IsoPSA Index Score 3.2
Demo results
Low Risk (<4.0) Intermediate Risk (4.0-11.5) High Risk (>11.5)
3.2

What this means

An IsoPSA index score of 3.2 falls in the low-risk range, suggesting your PSA structural pattern looks more like benign or low-grade prostate tissue rather than aggressive cancer. This is a reassuring result, though it doesn't guarantee the complete absence of prostate changes. Continued routine monitoring is still a good idea, especially if you have other risk factors.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
