Sorry to be so lengthy in my response, but here is a response from a VP at Biodynamics to give you and your doctor some more clarity:

Here is the comment made by Joe Abdo, the VP of Clinical Diagnostics for Oxford Biodynamics further r clarifying the PSE test:

"Just to clarify, the EpiSwitch PSE test analyses immune cells in the blood that have been at interplay with prostate cancer (or not). Your PSA value only makes up a small portion of the results of the test. There are other very informative biomarkers assessing the presence or absence of PCa included in this test. So yes, EpiSwitch PSE can still be used with a very low PSA score, and can still detect prostate cancer without PSA shedding. Therefore, the test can be used before, after and during treatment - even after complete prostate resection. In your case, a 'low likelihood' result could potentially help you avoid things like PSMA scans if your PSA indeed rises over time. A 'high likelihood' result could be indicative of recurrence, irrespective of low PSA."
