The intended use statement explicitly states that the test is "intended for use as an aid in the differential diagnosis of Influenza A and Influenza B in humans."
No
The device description clearly states that the system consists of an analyzer (hardware) and a single-use disposable assay tube (hardware/reagent) in addition to the software. It is an in vitro diagnostic system that integrates hardware, software, and reagents.
Based on the provided text, the device is indeed an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use/Indications for Use: The text explicitly states the device is for "rapid in vitro qualitative detection and discrimination of Influenza A virus and Influenza B virus RNA in nasopharyngeal swab specimens". The term "in vitro" is a key indicator of an IVD.
- Device Description: The description refers to the device as a "rapid, automated in vitro diagnostic test".
- Function: The device performs tests on biological samples (nasopharyngeal swabs) to detect and differentiate specific analytes (Influenza A and B viral RNA) to aid in diagnosis. This is the core function of an IVD.
- Regulatory Information: The mention of "CLIA Waived (CW150003)" and the intended users (Hospital nurse and CLIA moderate complexity laboratory technologist) further support its classification as a medical device used for diagnostic purposes.
- Predicate Device: The mention of a predicate device (K111387 Liat™ Influenza A/B Assay) which is also an Influenza A/B assay, suggests that this device is being compared to a previously cleared IVD.
Therefore, all the provided information points to the cobas® Influenza A/B Nucleic acid test for use on the cobas® Liat® System being an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The cobas® Influenza A/B Nucleic acid test for use on the cobas® Liat® System (cobas® Influenza A/B) is an automated multiplex real-time RT-PCR assay for the rapid in vitro qualitative detection and discrimination of Influenza A virus and Influenza B virus RNA in nasopharyngeal swab specimens from patients with signs and symptoms of respiratory infection in conjunction with clinical and evidemiological risk factors. The test is intended for use as an aid in the differential diagnosis of Influenza A and Influenza B in humans and is not intended to detect Influenza C.
Negative results do not preclude Influenza virus infection and should not be used as the sole basis for treatment or other patient management decisions. Conversely, positive results do not rule out bacterial infection or co-infection with other viruses. The agent detected may not be the definite cause of disease.
Performance characteristics for Influenza A were established when Influenza A/H1 and A/H3 were the predominant Influenza A viruses in circulation. When other Influenza A viruses are emerging, performance characteristics may vary.
If infection with a novel Influenza A virus is suspected based on current clinical and epidemiological screening criteria recommended by public health authorities, specimens should be collected with appropriate infection control precautions for novel virulent Influenza viruses and sent to state or local health department for testing. Viral culture should not be attempted in these cases unless a BSL3+ facility is available to receive and culture specimens.

Device Description
The cobas® Influenza A/B assay is a rapid, automated in vitro diagnostic test for qualitative detection and differentiation of Influenza type A and type B viral RNA. The assay is performed on the cobas® Liat® System. The system automates and integrates sample purification, nucleic acid amplification, and detection of the target sequence in biological samples using real-time RT-PCR assays. The cobas® Liat® Analyzer consists of an instrument and preloaded software for running tests and viewing the results. The cobas® Liat® System consists of the analyzer and a single-use disposable cobas® Influenza A/B assay tube that holds the sample purification and RT-PCR reagents and hosts the sample preparation and RT-PCR processes. Other than adding the sample to the cobas® Influenza A/B assay tube, no reagent preparation or additional steps are required. Because each cobas® Influenza A/B assay tube is self-contained, cross-contamination between samples is minimized. Turnaround time for a test is 20 minutes.
The cobas® Influenza A/B assay includes reagents for the detection and differentiation of Influenza A and B viral RNA in nasopharyngeal swab (NPS) specimens in universal transport media (UTM) from patients suspected of having Influenza. The assay targets a well-conserved region of the matrix gene of Influenza A viral RNA (Inf A target) and non-structural protein (NS) gene of Influenza B (Inf B target). An Internal Process Control (IPC) is also included. The IPC is present to control for adequate processing of the target viruses through all steps of the assay process and to monitor the presence of inhibitors in the RT-PCR reactions.
The cobas® Influenza A/B assay tube uses a flexible tube as a sample processing vessel. It contains all requisite PCR reagents pre-packed in assay tube segments separated by breakable seals. When a cobas® Influenza A/B assay tube containing a raw biological sample is inserted into the cobas Liat® Analyzer. multiple sample processing actuators in the cobas® Liat Analyzer compress the cobas® Influenza A/B assay tube to selectively release the reagents, moving the sample from one segment to the next, and controlling reaction conditions. An embedded microprocessor controls and coordinates these actions to perform all required assay processes, including sample preparation, nucleic acid extraction, target concentration enrichment, inhibitor removal, nucleic acid elution, and real-time PCR. All assay steps are performed within the closed and self-contained cobas® Influenza A/B assay tube, minimizing cross-contamination between samples.
The detection module monitors the reaction in real-time, while an on-board computer analyzes the collected data and outputs an interpreted result. The latter is displayed in the assay report on the integrated LCD touch screen of the cobas® Liat® Analyzer and in an electronic file. The report can be printed directly through a USB or network-connected printer. The results can also be exported to an external server, middleware or data management system, or to a Laboratory Information System (LIS).

A user then scans the assay tube barcode to identify the test and scans the sample barcode to code the sample ID using the cobas® Liat® System. The assay tube is then inserted into the cobas "Liate Analyzer. The analyzer performs all test steps and outputs interpreted results in 20 minutes. A report of the interpreted results can be viewed in the View Results window, and printed directly through a USB connected printer.

INTENDED USE 2.
The cobas® Influenza A/B Nucleic acid test for use on the cobas® Liat® System (cobas® Influenza A/B) is an automated multiplex real-time RT-PCR assay for the rapid in vitro qualitative detection and discrimination of Influenza A virus and Influenza B virus RNA in nasopharyngeal swab specimens from patients with signs and symptoms of respiratory infection in conjunction with clinical and evidemiological risk factors. The test is intended for use as an aid in the differential diagnosis of Influenza A and Influenza B in humans and is not intended to detect Influenza C.
Negative results do not preclude Influenza virus infection and should not be used as the sole basis for treatment or other patient management decisions. Conversely, positive results do not rule out bacterial infection or co-infection with other viruses. The agent detected may not be the definite cause of disease.
Performance characteristics for Influenza A were established when Influenza A/H1 and A/H3 were the predominant Influenza A viruses in circulation. When other Influenza A viruses are emerging, performance characteristics may vary.
5
If infection with a novel Influenza A virus is suspected based on current clinical and epidemiological screening criteria recommended by public health authorities, specimens should be collected with appropriate infection control precautions for novel virulent Influenza viruses and sent to state or local health department for testing. Viral culture should not be attempted in these cases unless a BSL3+ facility is available to receive and culture specimens.

DESIGN AND DEVELOPMENT ACTIVITY SUMMARY 5.
Roche Molecular Diagnostics (RMD), Pleasanton, CA created and formally released the assay script component of the cobas® Liat® System software. The cobas® Liat® Analyzer core software was created and released by Roche Molecular Diagnostics in Rotkreuz, Switzerland. For information on the development of the cobas® Liat® Analyzer, details of development activities associated with FABA v1.35 have been included in this submission.
RMD in Pleasanton coordinated the development and verification of cobas® Influenza A/B assay script v1.35 at the Product Requirements, Technical Requirements and Technical Requirement Specifications (Unit Specifications) level. These activities included risk management, requirements management, configuration management, verification testing, and regression analysis.
ASSAY PERFORMANCE 6.
Performance of the cobas® Influenza A/B assay with FABA v1.35 was evaluated using data from submissions (K111386, CW150003), internal studies, release testing, and the field. The result of this evaluation determined that the overall cobas® Influenza A/B assay performance and claims were not impacted by changes implemented in FABA v1.35, when compared to the current commercially available FABA script version.
7. CONCLUSION
Equivalent performance of the modified device and the current commercial device has been demonstrated, and analytical or clinical performance has not changed. The modified device is substantially equivalent to the predicate device, as originally cleared through K111386 and CLIA waived through CW150003.
