Device Classification

Product Code LJM Antinuclear Antibody (enzyme-labeled), Antigen, Controls
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 866.5100
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 Immunology devices follow this clearance model.
