K083273 is an FDA 510(k) clearance for the MICRODOT XTRA. Classified as System, Test, Blood Glucose, Over The Counter (product code NBW), Class II - Special Controls.

Submitted by Cambridge Sensors Limited (Huntingdon, Cambridgeshire, GB). The FDA issued a Cleared decision on November 19, 2009 after a review of 378 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1345 - the FDA in vitro diagnostics and chemistry framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Chemistry review framework, consistent with the majority of Class II 510(k) submissions.
