Test Code LAB239 URINE CULTURE

Important Note

This procedure covers a standard urine culture. Special cultures or nucleic acid amplification testing (NAAT) are required to identify uncommon causes of urinary tract infection this includes acid fast bacillus (mycobacteria), Ureaplasma, Metamycoplasma hominis, Chlamydia, and Neisseria gonorrhoeae. Anaerobic culture may be required. This is indicated by sterile pyuria, or other indications of infection from urinalysis wherein standard cultures are no growth or mixed growth with no clear pathogen. Urine will not routinely be evaluated for anaerobic growth.

Interpretation of Results

1. Each colony represents 1,000 colony forming units per ml (CFU/mL) for routine urine cultures.  

2. Maximum readable count is >100,000 CFU/mL, thus the maximum count reportable is greater than or equal to 100,000 CFU/mL.
