Test Overview
Test Methodology

Quantitative Culture

Test Usage

To isolate and identify organisms causing urinary tract infection

Reference Range *

No growth

Test Limitations

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.

Specimen Requirements
Collection Instructions

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.

Rejection Criteria
Specimen older than 24 hrs.
Normal Volume
10 mL urine
Minimum Volume
2 mL urine
Storage Temperature
Ambient: No
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.
