K834372 is an FDA 510(k) clearance for the PHA-1 PROGRAMMABLE HEMATOLOGY ANALYZ. Classified as Counter, Cell, Automated (particle Counter) (product code GKL), Class II - Special Controls.

Submitted by Diagnostic Technology, Inc. (Mchenry, US). The FDA issued a Cleared decision on February 10, 1984 after a review of 71 days - a notably fast clearance cycle.

This device falls under the Hematology FDA review panel, regulated under 21 CFR 864.5200 - 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.
