RT Journal Article SR Electronic T1 Evaluation of the Urotest AB antibacterial substance detection test. JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 1047 OP 1048 DO 10.1136/jcp.47.11.1047 VO 47 IS 11 A1 J M Blondeau A1 Y Yaschuk A1 D Galenzoski A1 D Hrabok A1 M Isaacson A1 L Lee A1 H Link A1 L Walshaw YR 1994 UL http://jcp.bmj.com/content/47/11/1047.abstract AB The Urotest AB was used to detect antimicrobial substances in urine samples. Of 1022 urine specimens evaluated, Urotest AB detected inhibitors in 38.9%. Of 159 urine specimens from patients thought to be taking an antibiotic, inhibitors were detected in 80.5%. This test may help to explain culture negative urine samples from symptomatic patients, and could help elucidate treatment failures and the epidemiology of antibiotic resistance.
