K241037 is an FDA 510(k) clearance for the ABL90 FLEX PLUS System. Classified as Electrode, Ion Specific, Potassium (product code CEM), Class II - Special Controls.

Submitted by Radiometer Medicals Aps (Brønshøj, DK). The FDA issued a Cleared decision on January 14, 2025 after a review of 273 days - an extended review cycle.

This device falls under the Chemistry FDA review panel, regulated under 21 CFR 862.1600 - 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: Standard predicate-based submission. Standard predicate reliance. This clearance follows a standard predicate-based equivalence path within the Chemistry review framework, consistent with the majority of Class II 510(k) submissions.

Device Classification

Product Code CEM Electrode, Ion Specific, Potassium
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 862.1600
What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. Clinical trial data may be submitted as supporting evidence to strengthen the substantial equivalence argument. Most Chemistry devices follow this clearance model.
