K183140 is an FDA 510(k) clearance for the MTS Tetracycline 0.016 - 256 ug/mL. Classified as Manual Antimicrobial Susceptibility Test Systems (product code JWY), Class II - Special Controls.

Submitted by Liofilchem S. R. L. (Roseto Degli Abruzzi, IT). The FDA issued a Cleared decision on January 11, 2019 after a review of 59 days - a notably fast clearance cycle.

This device falls under the Microbiology FDA review panel, regulated under 21 CFR 866.1640 - the FDA microbiology device framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: Fast-track predicate clearance. Standard predicate reliance. The short review cycle indicates strong predicate alignment - the FDA found sufficient equivalence without extended technical review.
