@Bluesky53 Yes, it's a blood test. I don't recall for sure but it should be below 7 if my memory serves me. Don't take that to the bank though. The person who draws your blood might know.
@Bluesky53 If you aren't having any symptoms you are probably fine. It's routine to check at your age because that's when men start getting BPH, or enlarged prostate. I've taken care of dozens of men who had a TURP. Not such a big deal.
@Bluesky53 Benign prostatic hypertrophy, aka enlarged prostate and TURP is transurethral resection of the prostate. But you're not there I'm sure or you'd be having symptoms. It's common among older men but not everyone gets it. Anyway you're still kind of young.
