Indications for Use
UCP Drug Screening Buprenorphine, Amphetamine 300, Methamphetamine 500, Cocaine 150 Tests are rapid, qualitative, competitive binding immunoassays and intended for qualitatively the detection of Buprenorphine, Amphetamine, Methamphetamine, Cocaine and their metabolites in human urine at the following cut-off concentrations: Buprenorphine 10 ng/mL, Amphetamine 300 ng/mL, Methamphetamine 500 ng/mL, Cocaine 150 ng/mL. The tests provide only preliminary test results, which should be confirmed by other methods such as gas chromatography/mass spectrometry (GC/MS) or liquid chromatography/mass spectrometry (LC/MS). Clinical considerations and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are indicated. The tests are not intended to be used in monitoring the drugs levels. For professional use only For In Vitro Diagnostics only
Device Story
UCP Rapid Drug Screening tests are lateral flow immunoassays for qualitative detection of buprenorphine, amphetamine, methamphetamine, and cocaine in human urine. Device formats include dipstick, cassette, and test cup. Principle of operation: competitive binding immunoassay; urine sample migrates via capillary action through membrane; drug in sample competes with immobilized drug conjugate for limited anti-drug antibodies labeled with colloidal gold. If drug concentration is below cutoff, anti-drug antibodies bind to immobilized drug antigen, forming visible test line (negative result). If drug concentration is at or above cutoff, no test line forms (preliminary positive). Control line confirms proper sample flow. Used in point-of-care settings by healthcare professionals. Results are visually read. Preliminary positive results require confirmation via GC/MS or LC/MS. Device aids in clinical decision-making regarding drug use.
Clinical Evidence
No clinical studies were performed. Performance was evaluated via method comparison study using 80 unaltered clinical urine samples per drug, compared against GC/MS or LC/MS/MS reference methods. Results demonstrated agreement between the candidate device and the reference method across all three formats (dip card, cassette, cup). Analytical performance (precision, cross-reactivity, interference) was established through bench testing using spiked urine samples.
Technological Characteristics
Lateral flow immunochromatographic assay; competitive binding format. Form factors include test strip, test device, and test cup. Standalone, non-instrumented, visual readout. In vitro diagnostic use.
Indications for Use
Indicated for the qualitative detection of Buprenorphine, Amphetamine, Methamphetamine, Cocaine, and their metabolites in human urine at specified cut-off concentrations. Intended for professional in vitro diagnostic use. Not for monitoring drug levels. Preliminary results require confirmation by GC/MS or LC/MS.

L. Test Principle:
UCP Drug Screening devices are a one-step lateral flow immunoassay containing a purple-colored conjugate pad with colloidal gold conjugate with anti-drug antibodies, a nitrocellulose membrane with a test line (T) and a control line (C). The T line is coated with the drug antigen and the C line is coated with goat anti-mouse IgG antibodies. The test is a competitive binding immunoassay in which drugs and drug metabolites in a urine sample compete with immobilized drug conjugate for limited labeled antibody binding sites. When a sufficient amount of sample is applied the sample migrates through the test device by capillary action. If the concentration of drug is below the cutoff level, the anti-drug antibodies in the colloidal gold particles will bind to the drug antigens coated in the test zone producing a band which indicates a negative result. If the drug concentration is at the cutoff level or higher no band will form in the test zone indicating a preliminary positive. A band should form in the control region regardless of the presence of drug or drug metabolite in the sample.

M. Performance Characteristics (if/when applicable):
1. Analytical performance:
a. Precision/Reproducibility:
Reproducibility was evaluated by spiking drug free negative urine to the following concentrations (Negative, 50%, 75%, 125%, 150% and 200% of the cutoff) for each analyte. Testing was performed at three Point-of-Care sites three operators/site each testing one of three formats. Each sample, at each concentrations of each drug, was blind labeled and tested 1 to 2 times a day, for 10 non-consecutive days. A total of 30 determinations, at each concentration, were made.

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.

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.
