K770074 is an FDA 510(k) clearance for the BIO-DYES FORTIFIED HEMATOLOGY STAIN. Classified as Wright's Stain (product code IAF), Class I - General Controls.

Submitted by Jack W. Kindberg (Mchenry, US). The FDA issued a Cleared decision on March 22, 1977 after a review of 68 days - a notably fast clearance cycle.

This device falls under the Hematology FDA review panel, regulated under 21 CFR 864.1850 - the FDA hematology device 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.
