I have OBD's offering given as one of three and its the most sensitive secondary test after a positive PSA test. Its the one strongly recommended which is pretty good imho.
They allow £250 for the secondary test in the report so considerably cheaper for the NHS than for private..
"Recent advances in diagnostic technologies offer the potential to improve the accuracy and efficiency of prostate
cancer screening while reducing unnecessary interventions. These innovations span improvements in new and
improved PSA-based blood testing (reflex testing), AI-supported imaging and integrated diagnostic workflows.
Reflex testing refers to an automatic follow-up blood test that is performed when a man’s initial PSA result
exceeds a defined threshold. Using additional biomarkers, these tests help detect clinically significant cancers,
reducing unnecessary MRI scans and biopsies.
One such development is the Stockholm3 test, a blood-based diagnostic that goes beyond the standard PSA
measurement. It combines plasma protein biomarkers, genetic markers and clinical data – including age, family
history and prior biopsy history – into a risk-prediction algorithm. Intended for use in individuals with a PSA level
of at least 1.5 ng/mL, Stockholm3 provides a score indicating the likelihood of prostate cancer, with a sensitivity
of 92% and specificity of 33%.33 The test has shown promise in reducing the number of unnecessary MRI scans
and biopsies by more accurately identifying men at higher risk of clinically significant disease.34
Another innovation is the EpiSwitch PSE test, which is administered alongside the PSA test. It analyses five
epigenetic biomarkers and integrates these data with the PSA result to improve diagnostic specificity.
The manufacturer reports an overall sensitivity of 94% and a specificity of 97%, suggesting strong potential
to reduce false positives and minimise the need for further diagnostic procedures in low-risk cases.35
A third promising blood test is Proclarix, which measures a panel of protein biomarkers alongside a software
algorithm that incorporates the patient’s age to generate a personalised risk score. The test has demonstrated
a 95% negative predictive value, meaning that it can reliably rule out clinically significant prostate cancer in
low-risk cases. In retrospective clinical studies, Proclarix achieved a 90% sensitivity and a specificity of 43%,
significantly outperforming the PSA test.36
