K890802 is an FDA 510(k) clearance for the COTUBE(TM) TSH IRMA. Classified as Radioimmunoassay, Thyroid-stimulating Hormone (product code JLW), Class II - Special Controls.

Submitted by Bio-Rad (Hercules, US). The FDA issued a Cleared decision on March 28, 1989 after a review of 40 days - a notably fast clearance cycle.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1690 - 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: Fast-track predicate clearance. Standard predicate reliance. The short review cycle indicates strong predicate alignment - the FDA found sufficient equivalence without extended technical review.
