Overview
Laboratory tests used in the diagnosis of prostatitis may include a CBC, urinalysis, serum PSA (prostate-specific antigen) level, urine culture, postvoid residual volume levels, 2-glass pre- and post-prostatic massage test, Stamey-Meares four-glass test, and a semen analysis.[1][2][3] Laboratory findings consistent with the diagnosis of acute prostatitis include increased leukocytes on CBC, bacteria seen on urine culture, elevated C-reactive protein, and transiently elevated PSA (prostate specific antigen) levels.[4] Laboratory findings consistent with the diagnosis of chronic bacterial prostatitis include negative pre-massage urine culture results, more than 10 to 20 leukocytes per high-power field in both the pre- and the postmassage urine specimen, bacteriuria in the postmassage urine specimen, and lower leukocyte and bacterial counts in voided bladder urine specimens as compared to bacterial count in post-prostatic massage voided urine or expressed prostatic secretions.
Laboratory findings
Laboratory Tests
Laboratory tests used in the diagnosis of prostatitis may include:[1][2][3]
- CBC
- Urinalysis
- Serum PSA (prostate-specific antigen) levels
- Urine culture
- Postvoid residual volume levels
- 2-glass pre- and post-prostatic massage test
- Stamey-Meares four-glass test
- Semen analysis
Laboratory Findings
Laboratory findings consistent with the diagnosis of acute prostatitis include:[4]
- Increased leukocytes on CBC
- Bacteria seen on urine culture
- Elevated C-reactive protein
- Transiently elevated PSA (prostate specific antigen) levels
Laboratory findings consistent with the diagnosis of chronic bacterial prostatitis include:[5]
- Negative pre-massage urine culture results
- More than 10 to 20 leukocytes per high-power field in both the pre- and the postmassage urine specimen
- Bacteriuria in the postmassage urine specimen
- Lower leukocyte and bacterial counts in voided bladder urine specimens as compared to bacterial count in post-prostatic massage voided urine or expressed prostatic secretions[3]
The Stamey-Meares localization method is used to differentiate between chronic nonbacterial prostatitis and other types of prostatitis. The absence of bacterial growth on cultures are diagnostic of chronic nonbacterial prostatitis. Leukocytosis may be present in the prostatic secretions. The premassage urine specimen contains <10 WBCs per high-power field, while the postmassage urine specimen has >10-20 WBCs per high-power field.[3]
