K903508 is an FDA 510(k) clearance for the LABELLING CHANGES TO IMPRES-MB-X. Classified as U.v. Method, Cpk Isoenzymes (product code JHW), Class II - Special Controls.

Submitted by Intl. Immunoassay Laboratories, Inc. (Santa Clara, US). The FDA issued a Cleared decision on September 7, 1990 after a review of 38 days - a notably fast clearance cycle.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1215 - 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.
