Device Classification

Product Code JLW Radioimmunoassay, Thyroid-stimulating Hormone
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 862.1690
What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. This pathway does not require clinical trials - it relies on engineering equivalence and performance data. Most Chemistry devices follow this clearance model.
