Prostate Specific Antigen (PSA) is a glycoprotein secreted by the prostate to enable sperms to move in the semen. It is also present in small amount in serum. As persistently raised PSA levels above the reference range can be due to prostate cancer, prostatitis and benign prostatic hyperplasia, it is appropriate to seek specialist advice as soon as possible.
Palpitation and other vital signs abnormalities can be associated with severe urinary tract infection. If any of these signs persists after full recovery from the infection, it is wise to consult a physician to find the root cause.
Semen culture is part and parcel of the investigation of bacterial prostatitis. A normal routine urinalysis cannot exclude prostatits.

ureaplasma urealyticum
I have tested for ureaplasma urealyticum (by PCR urine) twice before due to symptom of episodic penile urethral pain but none was detected. It was heard that ureaplasma urealyticum can hide in the prostate or in the epididymis. In this case, can a PCR urine test give an accurate result?

A negative PCR result indicates the absence of detectable DNA in the specimen, but does not rule out infection as false-negative results may occur due to inhibition of PCR, sequence variability, or the quantity of Ureaplasma urealyticum is too low for detection by the assay.
