THERMO SCIENTIFIC QMS EVEROLIMUS REAGENTS, CALIBRATORS AND CONTROLS
Microgenics Corp.
Adult renal transplant patient sample set
Clinical patient samples were used to establish calibration traceability and to perform method comparison studies against an LC-MS/MS reference method.
The QMS® Everolimus assay is intended for the quantitative determination of everolimus, the active ingredient of Zortress®, in human whole blood on automated clinical chemistry analyzers. The results obtained are used as an aid in the management of kidney transplant patients receiving Everolimus therapy. This in vitro diagnostic device is intended for clinical laboratory use only. The QMS® Everolimus Calibrators set is intended for use in calibration of the QMS Everolimus Assay. The QMS® Everolimus Controls set is intended for use in quality control of the QMS® Everolimus Assay.
Device Story
The QMS Everolimus Assay is an in vitro diagnostic system for measuring everolimus concentrations in human whole blood. It utilizes particle agglutination technology and competitive binding principles on automated clinical chemistry analyzers. Input consists of whole blood samples; the assay measures absorbance at 700nm. The degree of particle agglutination is inversely proportional to the concentration of free drug in the sample. The system uses a calibration curve derived from known calibrator concentrations to interpolate the drug concentration in unknown patient samples. The device is intended for use in clinical laboratories by trained personnel to assist clinicians in managing everolimus therapy for kidney transplant patients. The output provides quantitative drug levels, which clinicians use to adjust therapeutic dosing.
Clinical Evidence
Bench testing only. Performance evaluated via functional sensitivity (LOQ 2.0 ng/mL), precision (total run %CV ≤ 15.0%), and linearity. Method comparison against LC/MS showed strong correlation (System 1: R2=0.94; System 2: R2=0.95). On-board reagent stability confirmed for 30 days.
Indicated for quantitative determination of everolimus in human whole blood to aid in management of kidney transplant patients receiving everolimus therapy. For clinical laboratory use only.

{1}------------------------------------------------
In particle agglutination assays, the degree of agglutination (detected by optical method at 700m) is inversely proportional to the quantity of free drug in the reaction well. Henrio music pressming he on the particle which will cause it to agglutinate and will result in higher absorbance. If increased amount of competing drug is present in the sample, this will result in decreased binding of bound drug by the antibody, resulting in a relative decrease in particle agglutination. This in turn results in lowler absorbance.
The precise relationship between particle agglutination of the unlabeled drug in the sample is established by measuring the absorbance values of calibrators with known concentration of the The absorbance of unknown samples can be interpolated from the absorbance values of the drug. calibration curve and the concentration of the drug present in the sample can be calculated.

| | CEDIA® Sirolimus Assay (K034069) | |
| Intended Use | The CEDIA® Sirolimus Assay is an in vitro<br>diagnostic medical device intended for the<br>quantitative determination of sirolimus in human<br>whole blood using automated clinical chemistry<br>analyzers as an aid in the management of<br>sirolimus therapy in renal transplant patients<br>taking sirolimus. | The QMS® Everolimus Assay is intended for<br>the quantitative determination of everolimus,<br>the active ingredient of Certican®, in human<br>whole blood on automated clinical chemistry<br>analyzers. The results obtained are used as<br>an aid in the management of kidney transplant<br>patients receiving Everolimus therapy. |
| Test Principle | The CEDIA® Sirolimus Assay uses recombinant<br>DNA technology (US Patent No. 4708929) to<br>produce a unique homogenous enzyme<br>immunoassay system.16 The assay is based<br>on the enzyme β-galactosidase, which has<br>been genetically engineered into two inactive<br>fragments. These fragments spontaneously<br>reassociate to form fully active enzymes that, in<br>assay format, cleave a substrate, generating a<br>color change that can be measured<br>spectrophotometrically.<br>In the assay, analyte in the specimen competes<br>with analyte conjugated to one inactive<br>fragment of β-galactosidase for antibody<br>binding site. If analyte is present in the sample,<br>it binds to antibody, leaving the inactive enzyme<br>fragments free to form active enzymes.<br>If analyte is not present in the sample, antibody<br>binds to analyte conjugated to the inactive<br>fragment, inhibiting the reassociation of inactive<br>β-galactosidase fragments, and no active<br>enzyme is formed. The amount of active<br>enzyme formed and resultant absorbance<br>change are directly proportional to the amount<br>of analyte present in the sample. | The QMS® Everolimus Assay system is a<br>homogeneous assay utilizing particle<br>agglutination technology and competitive<br>binding principles.<br>In particle agglutination assays, the degree of<br>agglutination (detected by optical method at<br>700nm) is inversely proportional to the<br>quantity of free drug in the reaction well.<br>Hence, if no drug is present in the sample, the<br>antibodies in the QMS® Everolimus Antibody<br>Reagent (R1) will bind only to the bound drug<br>on the particle which will cause it to<br>agglutinate and will result in higher<br>absorbance. If increased amount of<br>competing drug is present in the sample, this<br>will result in decreased binding of bound drug<br>by the antibody, resulting in a relative<br>decrease in particle agglutination. This in turn<br>results in lower absorbance. The precise<br>relationship between particle agglutination and<br>concentration of the unlabeled drug in the<br>sample is established by measuring the<br>absorbance values of calibrators with known<br>concentration of the drug. The absorbance of<br>unknown samples can be interpolated from<br>the absorbance values of the calibration curve<br>and the concentration of the drug present in<br>the sample can be calculated. |

Two short videos show you everything — or skip straight to the written tutorial if you'd rather read. You can reopen this any time from the Tutorial button in the top bar.
Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
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.
