Interpreting positive urine cultures

Urine screening: an alternative to urine cultures.

Urine cultures represent one of the most commonly submitted specimens to a microbiology laboratory. In an attempt to manage effectively this type of specimen, Bac-T-Screen (BTS), nitrate and leukoestrase test were performed on all clean catch urine specimens sent for culture. Three hundred and four specimens were screened by these methods. The BTS, by itself, had the highest sensitivity, and sp...

Inappropriate Management of Asymptomatic Patients With Positive Urine Cultures: A Systematic Review and Meta-analysis

Background Mismanagement of asymptomatic patients with positive urine cultures (referred to as asymptomatic bacteriuria [ASB] in the literature) promotes antimicrobial resistance and results in unnecessary antimicrobial-related adverse events and increased health care costs. Methods We conducted a systematic review and meta-analysis of studies that reported on the rate of inappropriate ASB tr...

Fast and accurate prediction of positive and negative urine cultures by flow cytometry

BACKGROUND Urinary tract infection (UTI) is a widespread infectious disease in humans. Urine culture, a huge workload in the microbiology laboratory, is still the standard diagnostic test for UTI, but most of the cultures are negative. A reliable screening method could reduce unnecessary cultures and quicken reporting of negative results. METHODS We evaluated the usefulness of a flow cytometr...
