Screening for Asymptomatic Bacteria in the Urine during Pregnancy

The Bottom Line

All pregnant women should undergo a single urine test for bacteria between 12 and 16 weeks of pregnancy. If the test is positive, it should be repeated with a urine sample for culture being obtained. All women with bacteria present in their urine should be treated with appropriate antibiotics and have follow-up tests to insure that the urine is free of bacteria.
