Prostate Cancer

Can a Urinary Tract Infection Cause a High PSA?



My father-in-law is 68 recently had a urinary tract infection. He is on antibiotics to clear the infection. He had a PSA test during this infection with a 35 or 36 reading. Can that number be that high with this infection?


An acute urinary infection can raise the PSA to that level or higher.  In these situations I typically will repeat the PSA approximately 6 weeks after the infection has been adequately treated.  Not uncommonly, the number comes down quite a bit, oftentimes to normal levels.
