Evaluation of the mastascanelite image analysis system for measuring zones of inhibition in disc diffusion susceptibility tests.

Evaluation of the mastascanelite image analysis system for measuring zones of inhibition in disc diffusion susceptibility tests. Br J Biomed Sci. 2003 Jan;60(3):133-135 Authors: Clarke REH, Winstanley TG, Ridgway EJ Abstract In this evaluation a mastascanelite image analysis system is compared with manual measurement of disc diffusion inhibition zones. Data for 213 diverse organisms and a total of 1679 organism/antibiotic combinations gave an overall correlation coefficient of 0.988. The mean difference between readings was +0.425 mm, with 95% confidence limits of ±2.94 mm, and the majority of scanned zones (97.51%) fell within ±3 mm of the manual measurement. The mastascanelite system forms part of a laboratory suite and was found to be objective, accurate and rapid, reading and interpreting each plate in less than a second. Interfacing to the laboratory computer system facilitated data handling and performance control. PMID: 28696861 [PubMed]
