| Population |
All Pregnant Women | Men and Nonpregnant Women |
| Recommendation |
Screen with urine culture
Grade: A
| Do not screen.
Grade: D
|
| Detection and Screening Tests |
Asymptomatic bacteriuria can be reliably detected through urine culture.
The presence of at least 105 colony-forming units per mL of urine, of a single uropathogen, and
in a midstream clean-catch specimen is considered a positive test result.
|
| Screening Intervals |
A clean-catch urine specimen should be collected for
screening culture at 12–16 weeks' gestation
or at the first prenatal visit, if later.
The optimal frequency of subsequent urine testing during
pregnancy is uncertain.
|
Do not screen.
|
| Benefits of Detection and
Early Treatment |
The detection and treatment of asymptomatic bacteriuria
with antibiotics significantly reduces the incidence
of symptomatic maternal urinary tract infections
and low birthweight.
| Screening men and nonpregnant women for asymptomatic
bacteriuria is ineffective in improving clinical outcomes.
|
| Harms of Detection and
Early Treatment |
Potential harms associated with treatment of asymptomatic bacteriuria include:
- Adverse effects from antibiotics.
- Development of bacterial resistance.
|
| Other Relevant USPSTF Recommendations |
