Device Story
Kit provides positive/negative external quality control materials for FilmArray Global Fever Panel; used on FilmArray 2.0 systems. Positive control contains dried synthetic DNA segments; negative control contains no DNA. Controls processed like patient samples in injection vials. System performs nested multiplex RT-PCR followed by melting analysis. Positive control DNA sequences engineered with signature melting temperatures (Tm) distinct from pathogen targets to prevent false positives and enable specific detection by control-specific software modules. If control results fail, operator retests or decontaminates workspace. Output is qualitative 'Passed' or 'Failed' result. Used in clinical laboratory settings to monitor assay performance, verify system function, and mitigate contamination risks.
Clinical Evidence
Performance evaluated via prospective clinical study (317 tests) and multi-site reproducibility study (270 tests). Clinical study showed 99.1% overall agreement with expected results (Positive 99.4%, Negative 98.7%). Multi-site reproducibility study demonstrated 98.1% overall agreement (Positive 97.8%, Negative 98.5%). Repeatability study (45 positive/45 negative tests) showed 100% agreement. Failures were attributed to user error or suspected laboratory contamination, not device failure.
Technological Characteristics
Assayed quality control material; synthetic DNA in buffer/stabilizer. Nested multiplex RT-PCR with melting analysis. Single-use FilmArray Control Injection Vial format. Room-temperature stable (18-30°C). Software-based automated test interpretation and report generation. No biological hazards; non-infectious.
Indications for Use
Indicated for use as assayed quality controls to monitor performance of in vitro diagnostic nucleic acid testing for qualitative detection of FilmArray Global Fever Panel targets (Leptospira spp., Plasmodium spp., P. falciparum, P. vivax/ovale, Chikungunya virus) on FilmArray 2.0 systems.

The External Controls are referenced in the Quick Guide and product literature as Control Injection Vials. The use of room-temperature stable External Controls contained within an injection vial simplifies the workflow and allows for use of the External Controls in settings where access to refrigeration may be limited. Each individually packaged, ready-to-use FilmArray Global Fever External Control is processed separately according to the Instructions for Use, and follows the procedure as outlined in the Quick Guide for the FilmArray Global Fever External Control Kit. Each External Control Injection Vial is intended for a single use.
The Global Fever Panel External Control Kit is designed to mitigate the risk of control contamination and misuse when evaluating clinical samples on the FilmArray 2.0 System.
- Negative External Controls are tested using the Negative External Control protocol, which monitors for contamination from both external control material and target pathogens; it will fail if either is detected.
- The Positive External Control contains DNA sequences that produce signature amplicon melting temperature (Tm) values distinct from the amplicon Tm values produced by each of the pathogens detected by the Global Fever Panel. By design, the Positive ECM will not be detected when using the Global Fever Panel Whole Blood Protocol, and reciprocally, amplified pathogen-specific nucleic acid will not be detected when using the Positive External Control Protocol. Through modification of the sequence between the inner primers for each ECM target, the Tm value of the amplicon is shifted to higher or lower Tm values relative to the expected Global Fever Panel target amplicon while running the same Global Fever Panel pouches with the same physical pouch manipulation in the FilmArray 2.0 Instrument. Positive External Control-specific pouch module software detects the expected shifted Tm values as being from ECM amplicon, thereby evaluating the performance of the FilmArray 2.0 System. Also, the modification of the ECM sequence mitigates possible contamination events and does not cause false positives in clinical samples. In the unlikely event that Positive ECM or ECM amplicon is introduced into a patient sample, the resulting amplification Tm value(s) is not detected within the pathogen(s) Tm window in the Global Fever
{3}
Panel Whole Blood Protocol, where different Tm windows are used to detect amplified pathogen sequence.

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.
