Urinary Tract Infections in Children: Accuracy of a Novel Dipstick Biomarker Test via Bagged Urine Sampling

Background: Absolute levels of urinary neutrophil gelatinase-associated lipocalin (uNGAL) appear highly accurate to identify urinary tract infections (UTIs) in young children when obtained via catheterization. Prior studies have neither evaluated the accuracy of uNGAL levels in bag (likely contaminated) specimens nor assessed the accuracy of a dipstick (potential point-of-care (POC)) test to detect UTIs. Objective: To compare the overall accuracy and test characteristics of laboratory-based uNGAL, dipstick uNGAL, and POC urinalysis (UA) …
