The Comprehensive Urine Culture is performed to diagnose or confirm an infection in the urinary tract (the kidneys, bladder, or urethra, which is the tube that drains urine out of the body).
This culture is designed to quantitate the growth of significant bacteria when collected by the Clean Catch Guidelines or from indwelling catheters. Quantitative culturing of urine is an established tool to differentiate significant bacteruria from contamination introduced during voiding. This test has a reference range of less than 1,000 bacteria per mL. More than 95% of Urinary Tract Infections (UTI) are attributed to a single organism. Infecting organisms are usually present at greater that 100,000 per mL, but a lower density may be clinically important. In cases of UTI where more than one organism is present, the predominant organism is usually significant and others are probably urethral or collection contaminants. When multiple organisms are isolated from patients with indwelling catheters, UTI is doubtful and colonization likely.
Alternative Name(s): Urine, Routine Culture
Significant deviations from the normal range may require further evaluation by your physician.
Due to collection instructions the Urine Culture should not be collected at the same time as a Chlamydia/Gonorrhea specimen.
Culture, Urine, Routine
If culture is positive, identification will be performed.
Morning specimen preferred. Due to collection instructions the Urine Culture should not be collected at the same time as a Chlamydia/Gonorrhea specimen. Estimated turnaround for results is 3 business days. If confirmation testing is required, the estimated time may be extended.
