Urine dipstick for leukocyte esterase will reliably identify pyuria, but it is not specific for asymptomatic bacteriuria. (Pyuria may result from other inflammatory disorders of the genitourinary tract.) Urinary dipstick for nitrites is also of limited usefulness because of infection with non-nitrite-producing organisms, the delay between collection and testing of the specimen, and insufficient time since the last voiding for nitrites to be produced at detectable levels. The combination of the dipstick for leukocyte esterase and nitrites is more specific for asymptomatic bacteriuria than either test alone. Urinalysis with microscopic exam for bacteria is a useful, but non-quantitative, way to identify bacteriuria. [Ссылки доступны только зарегистрированным пользователям ]
