Home-testing for recurrent bacteriuria, using nitrite strips. 1978

D W Scheifele, and A L Smith

Follow-up of children with recurrent urinary infections would be simplified by an accurate home-testing program for detection of infection. We provided nitrite test strips to the parents of 30 girls with recurrent urinary infection to determine if twice weekly home testing of first-voided urine could reliably detect infection. Infections were documented by dip slides or colony counts indicating more than 10(5) bacteria per milliliter of urine. Twenty-four families (80%) complied over a mean study period of 11 months, detecting 28 of 30 episodes of bacteriuria (93%). No false-positive tests occurred. Urinary nitrate, the substrate for nitrite production by bacteria, was universally present (greater than 100 microgram/ml) in 80 children. The nitrite test is useful for home follow-up observation of children at high risk of bacteriuria if applied repeatedly by motivated parents.

UI	MeSH Term	Description	Entries
D007202	Indicators and Reagents	Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents.
