I'm 56 years old and started having some issues with urinating. Went to my family doctor and had my PSA tested. Results were 14.6. Referred to a urologist and two weeks later my PSA level was 8.0. He checked my prostate and said that he didn't feel anything abnormal. He did a K4 test and results are 41. I have done a lot of research and can't really find anything that actually explains it well. I'm waiting to have a biopsy done to determine if I have prostate cancer and if so, how advanced it is. Just wondering if anyone else has had this test, what the results were and the outcome. Thanks for any help.
