Retrospective clinical specimens were used to establish performance characteristics for multiple respiratory pathogens due to the low number of positive specimens available during the prospective clinical study.
Individuals suspected of respiratory tract infections
Not applicable for this study
Performance characteristics (sensitivity/specificity) for Bordetella pertussis, Coronavirus, Influenza A H1, Influenza A H3, Influenza A H1-2009, Influenza B, Mycoplasma pneumoniae, and Parainfluenza Virus
Indications for Use
FilmArray Respiratory Panel EZ (RP EZ) is a multiplexed nucleic acid test intended for use with the FilmArray 2.0 EZ Configuration instrument for the simultaneous qualitative detection and identification of multiple respiratory viral and bacterial nucleic acids in nasopharyngeal swabs (NPS) obtained from individuals suspected of respiratory tract infections. The following organism types are identified using the FilmArray RP EZ: Adenovirus, Coronavirus, Human Metapneumovirus, Influenza A subtype H1, Influenza A subtype H3, Influenza A subtype H1-2009, Influenza Virus, Human Rhinovirus/Enterovirus, Respiratory Syncytial Virus, Bordetella pertussis, Chlamydophila pneumoniae, and Mycoplasma pneumoniae. The detection and identification of specific viral and bacterial nucleic acids from individuals exhibiting signs and symptoms of a respiratory infection aids in the diagnosis of respiratory infection if used in conjunction with other clinical and epidemiological information. The results of this test should not be used as for diagnosis, treatment, or other management decisions. Negative results in the setting of a respiratory illness may be due to infection with pathogens that are not detected by this test or, lower respiratory tract is not detected by a nasopharyngeal swab specimen. Positive results do not rule out co-infection with other organisms: the agent(s) detected by the FilmArray RP EZ may not be the definite cause of disease. Additional laboratory testing (e.g. bacterial and viral culture, immunofluorescence, and radiography) may be necessary when evaluating a patient with possible respiratory tract infection.
Device Story
System consists of FilmArray RP EZ pouch and FilmArray 2.0 EZ Configuration instrument. Input: nasopharyngeal swab specimen. Process: automated nucleic acid purification, reverse transcription, and nested multiplex PCR; high-resolution DNA melt analysis confirms identity.

H. Intended Use:
1. Intended use(s):
FilmArray Respiratory Panel EZ (RP EZ) is a multiplexed nucleic acid test intended for use with the FilmArray 2.0 EZ Configuration instrument for the simultaneous qualitative detection and identification of multiple respiratory viral and bacterial nucleic acids in nasopharyngeal swabs (NPS) obtained from individuals suspected of respiratory tract infections. The following organism types and subtypes are identified using the FilmArray RP EZ: Adenovirus, Coronavirus, Human Metapneumovirus, Influenza A, Influenza A subtype H1, Influenza A subtype H3, Influenza A subtype H1-2009, Influenza B, Parainfluenza Virus, Human Rhinovirus/Enterovirus, Respiratory Syncytial Virus, Bordetella pertussis, Chlamydophila pneumoniae, and Mycoplasma pneumoniae. The detection and identification of specific viral and bacterial nucleic acids from individuals exhibiting signs and symptoms of a respiratory infection aids in the diagnosis of respiratory infection if used in conjunction with other clinical and epidemiological information. The results of this test should not be used as the sole basis for diagnosis, treatment, or other management decisions. Negative results in the setting of a respiratory illness may be due to infection with pathogens that are not detected by this test or, lower respiratory tract infection that is not detected by a nasopharyngeal swab specimen. Positive results do not rule out co-infection with other organisms: the agent(s) detected by the FilmArray RP EZ may not be the definite cause of disease. Additional laboratory testing (e.g., bacterial and viral culture, immunofluorescence, and radiography) may be necessary when evaluating a patient with possible respiratory tract infection.
Due to the small number of positive specimens collected for certain organisms during the prospective clinical study, performance characteristics for Bordetella pertussis, Coronavirus, Influenza A H1, Influenza A H3, Influenza A H1-2009, Influenza B, Mycoplasma pneumoniae, and Parainfluenza Virus were established primarily with retrospective clinical specimens. Performance characteristics for Chlamydophila pneumoniae were established primarily using contrived clinical specimens.
Due to the genetic similarity between Human Rhinovirus and Enterovirus, the FilmArray RP EZ cannot reliably differentiate them. A positive FilmArray RP EZ Rhinovirus/Enterovirus result should be followed-up using an alternate method (e.g., cell culture or sequence analysis) if differentiation is required.

{2}
Performance characteristics for Influenza A were established when Influenza A H1-2009, A H1, and A H3 were the predominant Influenza A viruses in circulation. Performance of detecting Influenza A may vary if other Influenza A strains are circulating or a novel Influenza A virus emerges. 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 departments for testing. Viral culture should not be attempted in these cases unless a BSL 3+ facility is available to receive and culture specimens.

I. Device Description:
The FilmArray Respiratory Panel EZ (RP EZ) consists of two basic components: the FilmArray RP EZ pouch and the FilmArray 2.0 EZ Configuration instrument. The description of this device is essentially the same as that of the FDA-cleared FilmArray Respiratory Panel (RP), except for the software modifications and the control reagent modifications described below. Please refer to FDA cleared 510(k) submissions k103175, k110764, k120267, k123620, and k143080 for detailed device descriptions.
Software Modifications:
1. Implemented a simplified EZ version of the software running on FilmArray 2.0 EZ Configuration instrument. This version includes updates/changes to the workflow, error handling, run browsing, instrument control, database management, notes and tags dialogue, report content, and software architecture. For example, this version removes the ability to use more than one FilmArray 2.0 instrument from a single connected laptop computer, the availability of the "FilmArray Dashboard", and user access to the "PCR Evaluator".
2. Introduced a new FilmArray RP EZ pouch module, which modified the test results from reporting the four Coronavirus types (i.e., Coronavirus 229E, Coronavirus HKU1, Coronavirus NL63, and Coronavirus OC43) and the four Parainfluenza virus types (i.e., Parainfluenza Virus 1, Parainfluenza Virus 2, Parainfluenza Virus 3, and Parainfluenza Virus 4) separately and independently to reporting a single 'combined' Coronavirus result and a single 'combined' Parainfluenza virus.

Control Reagent Modification:
A new external control panel that is available from Maine Molecular Quality Controls, Inc., Scarborough, ME (online at www.mmqci.com) was recommended for use with the FilmArray RP EZ. This external control panel consists of a set of ready-to-use positive and negative control solutions, along with a package insert explaining the expected results. This external control panel should be tested when receiving a new shipment of test pouches and when training a new user.

## Controls
External Positive and Negative Controls
A new external control panel that is available from Maine Molecular Quality Controls, Inc., Scarborough, ME (online at www.mmqci.com) is recommended to be used with the FilmArray RP EZ:
FilmArray RP EZ Control Panel M265, Part number M265
- RP EZ Positive M266, Part number M266
- RP EZ Negative M267, Part number M267
This external control panel is also available as BioFire Diagnostics Part Number CHEM-CTL-0001.
The external control panel consists of a set of ready-to-use positive and negative control solutions, along with a package insert explaining the expected results. The external control panel should be tested when receiving a new shipment of test pouches and when training a new user. This external control panel is the subject of separate 510(k) Premarket Notification K161573 from Maine Molecular Quality Controls, Inc., Scarborough, ME.
A field study was performed to assess the ability of the intended user to perform external control testing using the recommended control materials and testing procedure for the FilmArray Respiratory Panel EZ (RP EZ) in a CLIA-waived setting. The primary metric evaluated by this study was the ability of these users to acquire and accurately interpret FilmArray RP EZ results when testing the provided external control materials. The FilmArray RP EZ test was performed according to the manufacturer's instructions by users with training and educational backgrounds consistent with those in the CLIA-waived testing environment (i.e., the intended users). User training on use of the FilmArray RP EZ was limited to the training video and the quick guide provided with the FilmArray RP EZ system.
The external control panel tested in this study consisted of a positive mix containing synthetic targets for all FilmArray RP EZ analytes and a negative mix that contains no analytes. Multiple operators participated in this study at each of the three sites (a total of 16 different FilmArray RP EZ operators across the three sites). Testing
6
{6}
consisted of three positive and three negative controls run per day, and spanned a period of 10 days (total of 60 control runs per site). Three lots each of the external control panel and three lots of FilmArray RP EZ pouches were tested across all sites.
A total of 182 external controls were tested (91 positive and 91 negative) by FilmArray RP EZ users at two CLIA-waived clinical settings and one simulated testing setting (BioFire Diagnostics). Two test runs were excluded from final data analysis due to invalid results caused by internal pouch control failures. Data for the remaining 180 control tests are shown below in Table 1.
Table 1. Summary of FilmArray RP EZ External Controls Testing Results
| Site | Positive | Negative | Total |
| --- | --- | --- | --- |
| #1 | 30/30 (100%) | 28/30 (93.3%) | 58/60 (96.7%) |
| #2 | 30/30 (100%) | 30/30 (100%) | 60/60 (100%) |
| #3 | 30/30 (100%) | 30/30 (100%) | 60/60 (100%) |
| Total | 90/90 (100%) | 88/90 (97.8%) | 178/180 (98.9%) |
The control material testing in this study produced an unexpected result in two test runs. In both cases, expected negative control mixes produced Coronavirus detections. Retrospective analysis of the two instances did not lead to any correlation between the two events, other than the fact that both of these tests were performed at the same site. The day of testing, operator, instrument, pouch lot, control mix lot, and species of Coronavirus detected (i.e., NL63 vs 229E) were all different.
After examining the workflow, the timeline of events and the details of the runs, the most likely cause of both instances is determined to be due to carryover from a positive control that was loaded within close time proximity to the negative control. It is possible that the users disregarded the instructions to only handle one sample and pouch at a time.
As a way of introducing further mitigation measures to guard against potential carry-over contamination from the positive control material, additional warnings and guidelines (e.g., "the negative control test should be run before the positive control test" and "change gloves and clean the work area between preparation of each sample", etc.) have been added to the product labeling and the training video.
Overall, these data demonstrate that the intended user can accurately perform external control testing using the FilmArray RP EZ in a CLIA-waived setting.

O. System Descriptions:
1. Modes of Operation:
See Section, I. Device Description
2. Software:
FDA has reviewed applicant’s Hazard Analysis and software development processes for this line of product types:
Yes ☐ X or No ☐
a. Level of Concern:
The Level of Concern was established as moderate during the initial clearance for the FilmArray RP under k103175. The level has not changed.
b. Software Description:
The software description was updated. The changes from the last cleared version of the software include updates to the workflow, error handling, run browsing, instrument control, database management, notes and tags dialogue, report content, software architecture, introduction of the EZ pouch module (along with associated documentation), the combination of coronavirus assays into a single call and the combination of parainfluenza virus assays into single call for the CLIA-waived pouch module. The FilmArray EZ Pouch Module, as defined in the software, contains all the information that is needed to analyze and interpret the data from a FilmArray 2.0 instrument run. The fundamental elements of the pouch definition are the assays, array layout, controls, and interpretations.
Of note, the FilmArray RP EZ software removes the ability to use more than one instrument, removes the availability of the “Dashboard” and removes access to the “PCR Evaluator”.
The FilmArray RP EZ software is controlled by Windows-based software running on a laptop that is connected to one FilmArray 2.0 Instrument. The software has been designed to be simple to ensure that tests are correctly performed and test results are not misinterpreted. The descriptions provided appear to be acceptable.
c. Device Hazard Analysis (DHA):
The DHA was updated to reflect the risks of both Off-The-Shelf and FilmArray software in the context of the FilmArray RP EZ system. A tabular list of potential hazards and an assessment of risk posed by the software and any interactive components was provided. Risks were calculated and categorized as High, Medium, Low or Zero. Risks were deemed acceptable after appropriate mitigations were put in place to address each risk.

d. Software Design Specification (SDS):
SDS documentation was referenced and referenced accordingly. During software and firmware development, detailed development documents were produced under the Quality System. The design specifications drove the software and firmware development, dictated the behavior of the modules, and formed the basis of design verification. The documentation provided appears to be acceptable.
e. Software Requirements Specifications (SRS):
Updates were provided to the SRS documentation, produced under the Quality System. The SRS includes a summary list of the fundamental hardware and software components necessary to functionally implement the software changes for the FilmArray RP EZ. The submitted documentation appears to be acceptable.
f. Traceability:
Updates were provided to the trace matrix from design input to output, providing information showing traceability for hardware and software requirements, risk assessment, and validation, as applicable. The submitted traceability appears to be acceptable.
g. Verification and Validation (V&V):
Updates were provided to the V&V documentation. This information included a detailed description of validation activities, test protocol, pass/fail criteria and results of those activities. These V&V activities were tied through a trace matrix to system requirements and a risk assessment, where appropriate. These activities included verification that features that were originally available to the end user remained available and functional after the modifications were made. The submitted documentation appears to be acceptable.
h. Revision Level History (RLH):
An update was provided to the RLH. The latest version of the FilmArray RP EZ software is v2.100.16. The latest version removes the ability to use more than one instrument, and removes availability of the "Dashboard" and access to the "PCR Evaluator". The submitted RLH appears to be acceptable.
i. Architecture Design Chart:
An update was provided to the Architecture Design Chart including diagrams and charts describing workflow, general structure, available utilities and assay and instrumentation control/management from beginning of an assay run to data analysis to result output. This appears to be acceptable.
j. Unresolved Anomalies (UA):
An update was provided to the Unresolved Anomalies. One unresolved anomaly was identified that can have a minimal impact on the pre-production process, but cannot impact the released version of the software for the FilmArray RP EZ. Therefore, the statement and documentation appear to be acceptable.

1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
