@asgmiami1 Just to be clear (since you're new to our group), there is no actual blood test that directly detects prostate cancer yet: the closest we have is the "liquid biopsy" trials to try to detect circulating tumour cells, but they're still not ready for prime time yet with prostate cancer.

However, @wwsmith 's suggestion is still worth a look. "PSE" is a trademark owned by Oxford BioDynamics for the process of combining a regular PSA screening test with an epigenetic test (the "E") to help reduce false-positive diagnoses of de-novo prostate cancer. I'm not sure if it would be useful yet with your still-low PSA, but that's something you can discuss with your oncologist.
