K101390 is an FDA 510(k) clearance for the FASTPACK TSH IMMUNOASSAY. Classified as Radioimmunoassay, Thyroid-stimulating Hormone (product code JLW), Class II - Special Controls.

Submitted by Qualigen, Inc. (Carlsbad, US). The FDA issued a Cleared decision on August 13, 2010 after a review of 88 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. As a Special 510(k), this submission covers a manufacturer modification to an existing cleared device rather than a new device introduction.

Device pattern: Iterative device modification. Low regulatory complexity profile. This Special 510(k) clearance confirms that the manufacturer's modifications remained within the established regulatory envelope of the original cleared device.
