K192503 is an FDA 510(k) clearance for the GM501 Wash with Phenol Red and Gentamicin. Classified as Media, Reproductive (product code MQL), Class II - Special Controls.

Submitted by Hamilton Thorne Incorporated (Beverly, US). The FDA issued a Cleared decision on November 19, 2020 after a review of 434 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Obstetrics & Gynecology FDA review panel, regulated under 21 CFR 884.6180 - the FDA obstetrics and gynecology device 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: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Obstetrics & Gynecology submissions.
