I had PSA test. Prostate cancer test. Total PSA is 0.506 ng/mL and PSA free is 0.152. I think psa free is very low. Can you tell me results fine or??

Firstly. Reason for PSA testing in a24 year old is unclear. Pre test probability is very low making the positive predictive value of the test extremly low hence not neccessary to do. the numbers give are WNL and reflective of a small sized prostate gland which is consistent with your age.
