#### 4. Detection Limit:
The Limit of Detection (LoD) for CT, NG, TV and MG was determined using representative target microorganisms in pooled negative male and female urine, collected in Colli-Pee•Dx Urine Collection Kit and then tested with the cobas CT/NG and cobas TV/MG assays, respectively. For the preliminary LoD, five independent replicates were co-spiked with either CT/NG or TV/MG across a range of five concentrations. The LoD was confirmed by testing 20 replicates at the preliminary LoD for each microorganism to determine the concentration that gave positive test results in ≥95% of the samples (at least 19/20 replicates testing positive for each strain). Results are shown in Table 3.

# *Shelf-life Stability*
The Colli-Pee•Dx Urine Collection Kits underwent stability testing following exposure to real-time aging conditions to support a shelf-life of 12 months. For real-time aging, the Colli-Pee•Dx devices were stored at temperatures flanking the labeled storage temperature of 15°C to 30°C/59°F to 86°F. At each study time point, functional (cobas CT/NG and cobas TV/MG assays), chemical and physical (pH, Refractive Index, chemistry visual inspection, evaporation and visual inspection of plastics/labels/pouch) endpoints were evaluated in three (3) lots of devices at baseline and following exposure to the various test conditions. For functional performance testing, male and female negative urine matrix co-spiked CT and NG or TV and MG at concentrations representative of low-positive samples and analyte-negative samples were added to the aged Colli-Pee•Dx devices and tested. A subset of devices containing co-spiked urine samples were subsequently stored at 32°C for 33 days to evaluate stability of the microorganisms in the aged devices. Study results showed that the Colli-Pee•Dx devices performed as expected, with the results supporting a shelf-life of 12 months.
# *Sample Stability*
A sample stability study was conducted using replicates of analyte-negative male and female urine samples and positive samples (male and female negative urine matrix co-spiked with either CT and NG or TV and MG at concentrations representative of low-positive and/or high-positive samples). The study evaluated the Colli-Pee•Dx Urine Collection Kit performance for sample shipping and laboratory storage stability under the following test conditions:
- Simulated summer and winter transport profile cycling conditions (-10°C to 40°C/14°F to 104°F) representing extreme cold and hot temperatures for durations anticipated during a 130-hour (5-day) shipping period from the time of sample collection to receipt at the testing laboratory.
- Simulated summer and winter transport followed by 30 days of storage in the laboratory at temperatures (2°C to 30°C/36°F to 86°F)
At the study timepoints, both positive and negative sample in multiple replicates were tested with cobas CT/NG and/or cobas TV/MG assays. Expected results were obtained for all negative and positive samples at all conditions.

### C Clinical Studies:
The clinical performance of the Colli-Pee•Dx Urine Collection Kit is supported by the following datasets:
The clinical performance for male and female urine was established in K173887 and K190433 and data were leveraged based on the established equivalence.
A separate prospective clinical study was conducted, enrolling female participants, to support the performance of the Colli-Pee•Dx Urine Collection Kit for use with cobas CT/NG and cobas TV/MG assays. Female participants (n=1357) were enrolled at 11 enrollment sites across the US between November 3, 2025, and April 9, 2026. Each participant self-collected three specimens in simulated home environment following respective instructions for use: a urine specimen collected using the FDA-cleared on-label urine collection kit, a urine specimen collected using the Colli-Pee•Dx Urine Collection Kit, and a vaginal swab specimen collected using the FDA-cleared on-label kit. All specimens were tested per cobas CT/NG and cobas TV/MG assay instructions. The Colli-Pee•Dx Urine Collection Kit performance was calculated by comparing each urine collection device result to the paired vaginal swab result to determine the ratios (Colli-Pee•Dx Urine Collection Kit: on-label urine collection kit) of Positive Percent Agreement (PPA) and Negative Percent Agreement (NPA). The performance for each analyte is summarized in Table 6.

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.
