LexaMed Laboratories is ISO 13485 Certified, holds a State of Ohio drug license and DEA registration, and maintains a FDA registration for both medical devices and pharmaceuticals. LexaMed offers a full complement of microbiology and chemistry services in our corporate laboratories in Toledo, Ohio. We offer tests to support routine release testing such as sterility tests – product and biological indicator and LAL pyrogen testing. We further offer qualification testing such as disinfectant efficacy, preservative effectiveness and microbial limits testing (USP), D and z-value, steam BIER unit exposures, package and container closure integrity, and tissue culture. We also provide testing to support sterilization cycle validations such as bioburden quantitation, sterilant resistance, ethylene oxide residues and microbial identifications. LexaMed has established strategic relationships with several contract laboratories and can, therefore, address a wide range of testing requirement.
