K063705 is an FDA 510(k) clearance for the LITHIUM MICRO VOLUME ELECTRODE, THEOPHYLLINE, ISE CALIBRATORS 1, 2 AND 3, TDM.... Classified as Assay, Porphyrin, Spectrophotometry, Lithium (product code NDW), Class II - Special Controls.

Submitted by Thermo Electron OY (Vantaa, FI). The FDA issued a Cleared decision on October 9, 2007 after a review of 300 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Toxicology FDA review panel, regulated under 21 CFR 862.3560 - the FDA toxicology 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: Standard predicate-based submission. Standard predicate reliance. This clearance follows a standard predicate-based equivalence path within the Toxicology review framework, consistent with the majority of Class II 510(k) submissions.
