Synonyms/Keywords
Urine C and S, Urine Culture, Urology Workup
Specimen Requirements
| Fasting Required | Specimen Type | Preferred Container/Tube | Acceptable Container/Tube | Specimen Volume | Specimen Minimum Volume (allows for 1 repeat) |
|---|---|---|---|---|---|
| No | Urine, clean catch midstream, first morning specimen preferred | Sterile, Leak-proof container | VACUETTE® urine transport tube, No Additive | 1-6.5 mL | 1 mL |
Collection/Processing Instructions
Specimens should be delivered to the microbiology laboratory as soon as possible.
Culture of specimens older than 24 hours may lead to a reduction in recovery of microorganisms.
Suprapubic aspirates are submitted in the collection syringe WITHOUT NEEDLE or a sterile screw-capped container. For more information on Specimen Collection Media/Swab, see Specimen Transport Pictorial.

| Urine, Sterile Container | Refrigerated | ≤72 hours |
Rejection Criteria
| Urine in swab or Eswab™ |
| Urine >72 Hrs |
| Leaking containers |
| Non sterile containers (Hats) |

Test Information
For Urologist Use Only or in consultation with Doctoral Microbiologist/Pathologist.
Method is sensitive to 1,000 organisms/mL of urine. Voided and cath cultures containing 3 or more species are considered contaminated unless one organism is predominant. Gram stains are not routinely performed on urine submitted for culture; request separately, if desired. A colony count is reported.
Antimicrobial Susceptibility Testing (AST) will be performed on significant bacterial isolates with unpredictable patterns if standardized methods are available based upon Clinical Laboratory Standards Institute guidelines. Methods used include disk diffusion, minimum inhibitory concentration (MIC) by broth microdilution, or MIC by Etest®.
A listing of the tested and reported antimicrobial agents can be seen at Antimicrobial Susceptibility Panels. If testing against a specific antimicrobial agent is desired, contact the microbiology laboratory.
The microbiology laboratory uses selective reporting of susceptibility results in order to promote rational antimicrobial usage. For more information on selective reporting, please contact the microbiology technical manager.
Standardized AST is not available for all bacterial species, in which case an MIC determined by a non-standardized method and without interpretation may be available upon request. Contact the microbiology laboratory for more information.
