5Q’s “PSB” the next step in prostate cancer detection does tell you!
PSA gives you a signal — but not the full picture.
The next step is clarity. The PSB – 5Q’s Prostate Dx™ test goes beyond PSA by analyzing prostate-specific biomarkers to help interpret what your results actually mean. It provides a more reliable assessment of the likelihood of prostate cancer, helping distinguish real risk from unnecessary concern.
PSA elevation is common and non-specific. Millions of men receive an elevated PSA result each year. The majority who go on to biopsy do not have clinically significant cancer yet they undergo invasive procedures, imaging, and weeks of anxiety.
PSA alone cannot distinguish indolent from aggressive disease. Up to 70% of prostate biopsies are negative. MRI is expensive and capacity-limited.
Low-grade cancers are overdetected Clinically significant cancers can still be missed.


Instead of guessing based on indirect markers, ProstateDx™ helps identify which men are more likely to have clinically significant cancer and which men can safely continue monitoring.
Built for the exact moment when uncertainty begins.

ProstateDx™ transforms an elevated PSA into a quantified risk signal, allowing clinicians to adjust decision thresholds based on clinical intent.
High-sensitivity setting (≈95%): Prioritizes detection of clinically significant cancer — ideal for confidently ruling out missed disease.
High-specificity setting (up to ≈90%+) Focuses on reducing unnecessary biopsies — identifying patients most likely to benefit from intervention.
This flexible “risk slider” enables tailored decision-making, balancing diagnostic certainty with procedure avoidance.
Biopsy reduction potential: ~30–35%
Designed for scalability across CLIA-certified laboratories, our platform enables earlier detection of clinically significant disease while reducing unnecessary procedures.

If results show a low likelihood of clinically significant prostate cancer, the recommended path may be continued monitoring. This typically includes routine PSA testing and periodic follow-up to keep watch on prostate health while avoiding unnecessary procedures.
If results suggest increasing risk, your doctor may recommend further evaluation such as advanced imaging, additional biomarker testing, or a targeted biopsy to better understand what is changing.
If testing indicates a high likelihood of clinically significant cancer, your physician can move quickly toward diagnostic confirmation and treatment planning to address disease that requires intervention.
ProstateDx™ is a physician-ordered blood test that measures biologically active prostate cancer cells to improve decision-making after an elevated PSA.
Built for the exact moment when uncertainty begins.
5Q's blood-based approach creates better outcomes at every level of care from the exam room to the bottom line.
A biologically grounded decision. No more ordering a biopsy based on a number alone. Confidence that the workup is justified or that monitoring is safe.
Fewer unnecessary biopsies. Less prolonged anxiety. A clear next step, not a waiting game. Knowing the test looked at the biology, not just a number.
Reduced downstream costs from unnecessary procedures. Better resource allocation. A defensible, evidence-based diagnostic workflow.
Without a better diagnostic tool, the current cycle continues:
elevated PSA triggers workup, workup triggers anxiety, anxiety triggers biopsy, biopsy finds nothing actionable. Patients continue to be over-biopsied. Aggressive cancers continue to be detected later than they should be. The clinician continues to make high-stakes calls with low resolution data.
This is not a hypothetical risk. It is the current standard of care. ProstateDx™ exists to interrupt that cycle.

Traditional prostate cancer screening starts and often stops with PSA, a useful but blunt tool. A high PSA can signal cancer, but it can also mean an enlarged prostate, inflammation, or simply nothing at all. It doesn't tell your doctor what is actually happening at a biological level. That uncertainty is what leads to unnecessary biopsies, prolonged anxiety, and in some cases, overtreatment of cancers that never needed to be touched. ProstateDx™ goes further. It measures biologically active prostate cancer cells in your blood — the actual biology — and translates that into a clear risk score. It's not guessing based on a number. It's reading the signal your body is already sending. The result is a smarter, less invasive path to the answer you actually need.
Not at all. ProstateDx™ is a simple blood draw the same kind you'd get at any routine doctor's visit. No needles beyond that, no prep, no recovery time. That's exactly the point. Before ProstateDx™ the next step after an elevated PSA was often a biopsy, an uncomfortable, anxiety-inducing procedure that, up to 70% of the time, comes back negative. ProstateDx™ was built to change that. One blood draw can give your doctor the biological clarity they need, so a biopsy only happens when it truly should.
ProstateDx™ gives you and your doctor a single, easy-to-understand risk score from 0 to 100 that estimates the likelihood of clinically significant prostate cancer. It's not a yes or no answer, but it is something far more useful: a biologically grounded signal that helps your doctor decide whether a biopsy is truly necessary. A lower score means you may be able to skip the biopsy altogether and simply continue monitoring. A higher score means your doctor has the confidence to act without second-guessing a number alone. Either way, you leave with clarity, not more uncertainty.
Patients who have elevated or unclear screening results, family history concerns, or questions about cancer risk may benefit from additional biological insight. Your physician can help determine whether the test is appropriate for your situation.
