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. In most prostatic syndrome patients pathogen is not detected.[5][3][6] The absence of bacterial growth on cultures is diagnostic of chronic nonbacterial prostatitis.[3][7]
Laboratory findings
Laboratory Tests
Laboratory tests used in the diagnosis of prostatitis may include:[1][2][3] [8]
- CBC
- Urinalysis
- Serum PSA (prostate-specific antigen) levels
- Urine culture
- Postvoid residual volume levels (a tense bladder or symptoms after voiding may be suggestive)
- 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[2]
- Increased leukocytes (>10 per high power field) 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:[6]
- 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]
Postvoid Residual Urine
Post void residual urine is an important investigation done in case of a suspicion of obstruction. Obstruction by BPH or kidney stones can lead to episode of acute prostatitis or may also cause chronic prostatitis.[2][9]
Stamey-Meares Method
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 is 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][10]
Prostatic Massage
The prostatic massage can be helpful in diagnosing some types of prostatitis[11][12]
- Chronic inflammatory prostatitis or asymptomatic inflammatory prostatitis can be differentiated by the appearance of leukocytes in expressed prostatic secretions which previously did not show leukocytes.
- Chronic bacterial prostatitis is diagnosed if the cultured organisms increase 10 times in a urine sample taken after prostatic massage or in expressed prostatic secretions.
Differentiation on the basis of laboratory findings
The following table can help in differentiating prostatitis on the basis of laboratory findings:[13][14][15]
