title: Asymptomatic bacteriuria in adolescent girls: II. Screening methods.
abstract: Of 500 asymptomatic adolescent girls who were screened for bacteriuria by three methods-dipslide (Uricult), dipstrip (Microstix-3 reagent strips), and home nitrite test (Microstix-Nitrite reagent strips)-eight cases (1.6%) were detected: 6/8 by dipslide and dipstrip; 5/8 by nitrite testing. The false-positive-rate (greater than 10(4) colonies/ml) of the dipslide test was 6.4%, and the dipstrip test, 2.8%. A history of vaginal discharge was not associated with "contaminated" specimens. False-positive nitrite tests were reported by 0.6% of the patients who returned the postcards. Overall, 70.4% of the patients returned the postcards for the home nitrite test. The patients were divided by method of payment (Medicaid vs non-Medicaid) in order to provide an approximation of socioeconomic status; non-Medicaid patients were significantly more likely to return postcards than Medicaid patients (75.8% vs 63.7%). Of the group reporting previous urinary tract infection, 79% of both Medicaid and non-Medicaid patients returned postcards, suggesting that a prior experience with the diagnosis increased compliance with a home test.
