K222771 is an FDA 510(k) clearance for the Sample Preservative Fluid. Classified as Microbial Nucleic Acid Storage And Stabilization Device (product code QBD), Class II - Special Controls.

Submitted by Hangzhou Bioer Technology Co., Ltd. (Hangzhou, CN). The FDA issued a Cleared decision on June 26, 2024 after a review of 651 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Microbiology FDA review panel, regulated under 21 CFR 866.2950 - 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.
