Urine Culture, Prenatal, With Group B Streptococcus Susceptibility Reflex
Use
Evaluation of pregnant women for asymptomatic bacteriuria has been recommended.1
Special Instructions
Not provided.
Limitations
A single culture is about 80% accurate in detecting bacteriuria in females. If antimicrobial therapy is administered at the time of specimen collection, any level of bacteriuria may be significant. When more than two organisms are recovered, it may indicate contamination, undermining the significance of identification and susceptibility testing. Specimens from Foley catheters may represent colonization rather than true bacteriuria.
