The definition of ASB5 in patients without indwelling catheters is ≥10 cfu/mL (≥10 cfu/L) in a voided urine specimen without signs or symptoms attributable to 8UTI.
  • For women, two consecutive specimens should be obtained, preferably within 2 weeks, to confirm the persistence of bacteriuria. From 10–60% of women, varying with the population, do not have persistent bacteriuria on repeat screening after an initial positive specimen.
  • For men, a single urine specimen meeting these quantitative criteria is sufficient for diagnosis.
Observational and intervention studies evaluating long-term screening and treatment in school children and healthy women suggest that ASB is benign in children and in women who were not pregnant. In addition, efforts to maintain sterile urine are often futile.

Screening for and treatment of ASB is only recommended for pregnant women and prior to endourologic procedures.

Studies in other populations suggest that antimicrobial treatment does not confer any benefits, but does increase the risk of adverse outcomes including antimicrobial resistance and Clostridiodes difficile infection. In some cases the risk of UTI shortly following therapy may be increased.
