K841803 is an FDA 510(k) clearance for the A1 SYSTEME 8201/2. Classified as Counter, Cell, Automated (particle Counter) (product code GKL), Class II - Special Controls.

Submitted by Med USA (Waltham, US). The FDA issued a Cleared decision on February 25, 1985 after a review of 300 days - an unusually long review period, suggesting complex equivalence evaluation.

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: Standard predicate-based submission. Standard predicate reliance. This clearance follows a standard predicate-based equivalence path within the Hematology review framework, consistent with the majority of Class II 510(k) submissions.
