Substantial equivalence argument

The FDA determined substantial equivalence by comparing this device to legally marketed predicate devices that existed prior to May 28, 1976, or to reclassified devices under the Federal Food, Drug, and Cosmetic Act. The device is classified as Class II (Antimicrobial Susceptibility Test Powder) under regulation 21 CFR 866.1640. The submission included a Predetermined Change Control Plan (PCCP) that was reviewed and cleared as part of the substantial equivalence determination, allowing for future modifications consistent with the PCCP without new premarket notification.
