Current and clinically relevant antibiotic susceptibility panels

Antibiotic susceptibility panels run at IDEXX Reference Laboratories are based on specimen type/site, species, and organism.
Our team of scientists and specialists reviews and updates panels frequently to incorporate newer and more effective antibiotics guided by Clinical and Laboratory Standards Institute (CLSI) guidelines.
IDEXX uses the VITEK 2 (bioMérieux) automated platform, delivering accurate results hours or days faster than manual methods.
