Laboratory Tests

• Serum PSA: The combination of PSA and DRE of the prostate is used to screen for prostate cancer, which could also cause an enlarged prostate. Also PSA is a surrogate marker for an enlarged prostate due to BPH. Using a PSA greater than 1.5 ng/ mL (1.5 mg/L) suggests that a patient has a prostate volume greater than 30 mm (30 g or 1.05 oz).

• Urinalysis to rule out infection as a cause of the patient's voiding symptoms; also check urinalysis for microscopic hematuria, which typically accompanies BPH.

• Plasma blood urea nitrogen (BUN) and serum creatinine may be increased as a result of long-standing bladder outlet obstruction. These tests are not routinely performed but rather are reserved for those patients in whom renal dysfunction is suspected.
