## Predicate Device Equivalence:
Substantial equivalence is claimed to the Diabetes Technologies, Inc. Accu-Base Hemoglobin Arc Sample Collection Kit, cleared for commercial distribution per K983172.
## Device Description:
The Appraise-Cardio Sample Collection Kit is a Sample Collection Kit which is sent to the patient's home after the kit has been ordered by the patient's physician. The kit consists of the following:
- A Sample Collection Tube. -
- A Sample Collection Capillary Tube. -
- -A Sample Tube Holder Box.
- A Patient Identification Card which contains the patient's name, address, Social Security Number, t information, the physician's name and phone number and a bar code number that is peeled off and affixed to the Sample Collection Tube after the sample has been taken.
- A pamphlet containing detailed information about the lipid program and instructions on how to obtain a blood sample and mail it to a laboratory.

- A plastic zip lock bag marked "Specimen Collection Envelope" into which the Sample Collection Tube is placed.
- An absorbent pad that is contained in the Specimen Collection Envelope. -
- A plastic zip lock bag marked "Waste". -
- A self-adhesive envelope in which the specimen envelope is inserted and then mailed to the preprinted address on the envelope.
- -A sterile lancet
- -An alcohol swab
- A sterile gauze pad -
- -A sterile adhesive bandage
- The mailing envelope which is used to mail the above items to the patient. .
The Sample Collection Tube, Sample Collection Capillary Tube, lancet, alcohol swab, gauze pad and adhesive bandage are all legally marketed, commercially available items.
After receiving the Appraise-Cardio Sample Collection Kit in the mail, the patient then collects a blood sample, using a lancet supplied in the kit or purchased separately by the patient. The blood sample is placed in the Sample Collection Tube as described in the instructions. The bar code sticker from the Patient Identification Card is then affixed to the Sample Collection Tube which is then placed in the Specimen Collection Envelope. The Patient Information Card and Specimen Collection Envelope are then placed in the mailing envelope. The mailing envelope is then sealed and sent to a laboratory for processing. When the blood sample is received by the laboratory the patient's total cholesterol, triglycerides and HDL values are measured using existing reagent kits.
## Intended Use:
The Appraise-Cardio Sample Collection Kit is a prescription device indicated for use for obtaining a blood specimen which can be collected at the patient's home or at a physician's office in a sample collection tube and delivered to the laboratory by mail. This specimen is then used to determine the patient's total cholesterol, triglycerides, HDL and LDL values. The results are then mailed to the patient's physician for evaluation.
## Comparison of Technological Characteristics:
Essentially, the two devices use the same basic technology, i.e., collecting a whole blood sample and analyzing it using an existing assay methodology. However, the blood parameters being measured are different for the two devices and thus the assay methodologies are different.
## Summary of Device Testing:
To obtain assurance that the whole blood samples would still provide an accurate assessment of the patients' total cholesterol, triglycerides. HDL and LDL even after undergoing the extreme temperatures and humidity conditions that can be experienced by any object sent by U.S. Mail, the Appraise-Cardio Sample Collection Kit was subjected to environmental testing. The results were within acceptable limits.
#### Conclusions:
Based on the above, we concluded that the Appraise-Cardio Sample Collection Kit is substantially equivalent to a legally marketed predicate device and is safe and effective for its intended use.

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.
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.
