## SUMMARY OF 510(K) SAFETY AND EFFECTIVENESS INFORMATION
This summary of 510(k) safety and effectiveness information is being submitted in accordance with the requirements of SMDA 1990 and 21 CFR 807.92.
The ATAC Iron Reagent Kit and ATAC TIBC Column Kit are intended for the quantitative determination of total iron and total iron binding capacity in serum. Total iron results are used for the diagnosis and treatment of diseases such as iron deficiency anemia, hemochromatosis (a disease associated with widespread deposit in the tissues of two iron-containing pigments, hemosiderin and hemofuscin, and characterized by pigmentation of the skin), and chronic renal iron binding capacity measurements are used for the diagnosis and treatment of anemia.
The ATAC Iron Reagent measures total serum iron by stripping it from the transferrin in a low pH reagent buffer, oxidizing it to ferric ions and binding it with Ferrozine. The resulting increase in absorbance at 546 nm is proportional to the iron concentration in the sample. The ATAC TIBC Column Kit is used to pretreat serum specimens prior analysis. The iron in the saturating reagent ensures that all available iron binding sites in the serum specimen are saturated with iron. The filtrate is assayed with an iron reagent after removing the unbound iron form the sample mixture by passing it through an alumina column. The maximum amount of iron bound in the specimen is a measure of its transferrin concentration.
The ATAC Iron Reagent Kit, which contains the Iron Calibrator (500 ug/dL), is substantially equivalent to the Beckman Synchron Systems Iron Reagent, product 467910 and the Beckman Systems Fe/IBCT Calibrator, product 442772. The ATAC TIBC Column Kit and ATAC 8000 TIBC application is substantially equivalent to the Beckman Synchron Systems Total Iron Binding Capacity (IBCT) Column Kit, product no. 465976 (Beckman Coulter, Inc. of Brea, CA).
The effectiveness of ATAC Total Iron Reagent Kit on the ATAC 8000 Random Access Chemistry System is shown in the following studies.
The recovery of iron using the ATAC Total Iron Reagent is linear from 25 to 500 µg/dL, as shown by the recovery of linearity standards that span the usable range. Regression statistics that compare standard values yield a standard error estimate of 3.1 ug/dL.
Precision is demonstrated by the replicate assay of commercially available control serum. Precision statistics, calculated analogous to the method described in NCCLS Guideline EP3-T, are shown below.
| Sample | n | mean | Within Run | | Total | |
|---------|----|------|------------|------|-------|------|
| | | | 1SD | %CV | 1SD | %CV |
| Serum 1 | 60 | 67 | 1.5 | 2.2% | 2.9 | 4.3% |
| Serum 2 | 60 | 177 | 1.9 | 1.1% | 4.4 | 2.5% |
| Serum 3 | 60 | 282 | 4.3 | 1.5% | 8.5 | 3.0% |
Serum specimens, collected from adult patients, were assayed for iron using the ATAC 8000 Random Access Chemistry System and another commercially available method. Results were compared by Deming regression and the following statistics were obtained.
> ATAC 8000 = 8.8 ug/dL + 0.969 x Competitive Reagent Sy.x = 3.0 µg/dL n = 58 range = 31 - 165 ug/dL
The 14 day onboard reagent stability and 7 day calibration stability claims are documented through the assay of serum controls over the claimed periods. In all cases, estimates of the total imprecision of iron recoveries over the test periods are less than the greater of 4 ug/dL or 4%.
{1}------------------------------------------------
The effectiveness of ATAC TIBC Column Kit is shown in the following studies with the ATAC Total Iron Reagent Kit on the ATAC 8000 Random Access Chemistry System.
TIBC recoveries using the ATAC TIBC Column Kit are linear from 125 to 500 µg/dL, as shown by the recovery of diluted serum pools that span the usable range. Regression statistics that compare standard recoveries to dilution factors yield an estimate of standard error of regression of 6 µg/dL.
Precision is demonstrated by the replicate assay of commercially available control serum. Precision statistics, calculated analogous to the method described in NCCLS Guideline EP3-T, are shown below.
| Sample | n | mean | Within Run | | Total | |
|---------|----|------|------------|------|-------|------|
| | | | 1SD | %CV | 1SD | %CV |
| Serum 1 | 60 | 247 | 4.5 | 1.8% | 4.9 | 2.0% |
| Serum 2 | 60 | 391 | 7.6 | 1.9% | 10.7 | 2.8% |
Serum specimens, collected from adult patients, were assayed for iron using the ATAC 8000 TIBC Application and another commercially available method. Results were compared by Deming regression and the following statistics were obtained.
> ATAC 8000 = 8.2 ug/dL + 0.964 x Competitive Reagent range = 237 - 470 ug/dL Sy.x = 7.8 µg/dL n = 55

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.
