K202977 is an FDA 510(k) clearance for the Alinity m STI Assay. Classified as Nucleic Acid Detection System For Non-viral Microorganism(s) Causing Sexually Transmitted Infections (product code QEP), Class II - Special Controls.

Submitted by Abbott Molecular, Inc. (Des Plaines, US). The FDA issued a Cleared decision on April 29, 2022 after a review of 576 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Microbiology FDA review panel, regulated under 21 CFR 866.3393 - the FDA microbiology 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: 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 Microbiology submissions.

Device Classification

Product Code QEP Nucleic Acid Detection System For Non-viral Microorganism(s) Causing Sexually Transmitted Infections
Device Class Class 2 - Special Controls
CFR Regulation 21 CFR 866.3393
Definition A Device To Detect Nucleic Acids From Non-viral Microorganism(s) Causing Sexually Transmitted Infections Is An In Vitro Diagnostic Device Intended For The Detection And Identification Of Nucleic Acids From Non-viral Microorganism(s) In Clinical Specimens Collected From Patients Suspected Of Sexually Transmitted Infections. The Device Is Intended To Aid In The Diagnosis Of Non-viral Sexually Transmitted Infections In Conjunction With Other Clinical And Laboratory Data.
What this classification means

Class II devices require demonstration of substantial equivalence to a legally marketed predicate device. This pathway does not require clinical trials - it relies on engineering equivalence and performance data. Most Microbiology devices follow this clearance model.
