Test Overview
Quantitative Culture
To isolate and identify organisms causing urinary tract infection
No growth
Pathogens present in numbers greater than or equal to 100 CFU/mL are reported if isolated. Cultures growing 3 or more potential pathogens will be rejected. Normal skin flora includes: coagulase negative Staphylococcus (unless predominant), alpha and gamma streptococci, Neisseria sp not (N. gonorrhoeae or N. meningitidis), Micrococcus, diphtheroids/Lactobacillus, and Bacillus sp (not B. anthracis). For acceptable specimens, all potential pathogens isolated will be identified. Anaerobic organisms will not be isolated.
Test Details
Preliminary results are reported in 18-24 hours. Negative results are reported after 2 days.

Specimen Requirements
Collect bladder tap, ureter aspirate, or suprapubic aspirate following sterile preparation of aspiration site. For optimum recovery, send immediately. If specimen must be stored, refrigerate immediately after specimen collection. Indicate on the requisition if the patient is renal, nephrology or transplant patient.
Refrigerated: Up to 24 hrs
Frozen: No
Additional Information
The source must be documented as Suprapubic when order is placed. This urine culture is appropriate for renal, nephrology and transplant patients where low colony count information can be clinically useful. For other patients, request a clean catch urine culture. Test includes culture and Gram stain smear if sufficient specimen is received and Gram stain is requested. Potentially pathogenic organisms will be identified. Test includes susceptibility testing of potentially pathogenic organism(s) at an additional charge unless specifically declined.
