Neutrophil Gelatinase-Associated Lipocalin Biomarker and Urinary Tract Infections: A Diagnostic Case-Control Study (NUTI Study).

Objectives: Acute uncomplicated urinary tract infection (UTI) in women is often treated based on symptoms alone. Urinary tract infection symptoms are highly sensitive but lack specificity and result in overuse of antibiotics. We sought to determine if urine neutrophil gelatinase-associated lipocalin (uNGAL) levels in urine can accurately discriminate between UTI and healthy women.
