CFR § 866.1650 A cellular analysis system for multiplexed antimicrobial susceptibility testing

§ 866.1650 A cellular analysis system for multiplexed antimicrobial susceptibility testing.

(a) Identification. A cellular analysis system for multiplexed antimicrobial susceptibility testing is a multiplex qualitative and/or quantitative in vitro diagnostic device intended for the identification and determination of the antimicrobial susceptibility results of organisms detected in samples from patients with suspected microbial infections. This device is intended to aid in the determination of antimicrobial susceptibility or resistance when used in conjunction with other laboratory findings.

(b) Classification. Class II (special controls). The special controls for this device are:

(1) Design verification and validation must include:

(i) Detailed device description documentation, including the device components, ancillary reagents required but not provided, a detailed explanation of the methodology, including primer/probe sequence, design, rationale for sequence selection, and details of the antimicrobial agents, as applicable.

(ii) Detailed documentation from the following analytical and clinical performance studies: limit of detection, inclusivity, precision, reproducibility, interference, cross-reactivity, carryover, and cross-contamination, quality control and additional studies, as applicable to specimen type and assay intended use.

(iii) Detailed documentation from an appropriate clinical study. The study, performed on a study population consistent with the intended use population, must compare the device performance to results obtained from well-accepted reference methods.

(iv) Detailed documentation for device software, including software applications and hardware-based devices that incorporate software.

(2) The labeling required under § 809.10(b) of this chapter must include:

(i) Limitations and protocols regarding the need for correlation of results by standard laboratory procedures, as applicable.

(ii) A detailed explanation of the interpretation of results and acceptance criteria.

(iii) A detailed explanation of the principles of operation and procedures for assay performance and troubleshooting.
