[Hopefull4567]

Hi has anyone had a prostate blood test.
My dad has been being monitored for few months now where his blood test has been around 6.
He had an mri which looked ok but because of his hip operation they couldn't see it fully.
So he went back last week for a check up and another blood test and the results have jumped from 6 to 9 I heard the norm is 4 or below.he is now having a biopsy Thursday to check for cancer.
Has anyone else had high psa results and been ok
