K810948 is an FDA 510(k) clearance for the RADIOIMMUNOASSAY THYROID STIM. HORM. KIT. Classified as Radioimmunoassay, Thyroid-stimulating Hormone (product code JLW), Class II - Special Controls.

Submitted by Endocrine-Metabolic Center (Mchenry, US). The FDA issued a Cleared decision on April 17, 1981 after a review of 10 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.
