Indications for Use
The GEM® Premier 3000 is a portable system for use by health care professionals to rapidly analyze whole blood samples that was originally cleared for the U.S. market by K992834, with glucose and lactate parameters added by K010520. Intelligent Quality Management (iQM") is being introduced on the GEM® Premier 3000 as an active quality process control program designed to provide continuous monitoring of the analytical process with real-time, automatic error detection, automatic correction of the system and automatic documentation of all corrective actions, replacing the use of traditional external quality controls. As part of this program, GEM® CVP (Calibration Validation Product) is intended for the external verification of the iQM" cartridge calibration after initial warm-up to ensure its integrity. The reported values for the four levels of GEM® CVP (two levels for pH, blood gases, electrolytes and metabolites; two levels for hematocrit) must meet specifications before the iQM" cartidge can be used for patient sample measurements. Once the cartridge calibration is verified, the internal iOM " program monitors the status of the system during the cartridge use life. To ensure that a total quality management system is adhered to, laboratories should follow local, state and federal regulatory guidelines. As with any analytical device or computer software, there is always the potential for software failure. However, IL conducts rigorous testing and extensive software validation prior to releasing a software revision. If the user encounters a rare software error code, it should be reported to your local IL Technical Support Representative.
Device Story
GEM Premier 3000 is a portable whole blood analyzer. iQM (Intelligent Quality Management) provides continuous, real-time monitoring of the analytical process; replaces traditional external quality controls. System uses GEM CVP (Calibration Validation Product) for initial external verification of cartridge calibration. Once verified, iQM monitors system status during cartridge life; performs automatic error detection, correction, and documentation. Used by healthcare professionals in clinical settings. Output includes analyte values (pH, blood gases, electrolytes, metabolites, hematocrit). Benefits include real-time malfunction detection and reduced reliance on manual external QC. System detects interferences (e.g., Benzalkonium, Thiopental Sodium) and flags failed analytes.
Clinical Evidence
Bench testing only. Precision study (N=135) across 9 instruments evaluated pH, blood gases, electrolytes, metabolites, and hematocrit. Method comparison (N=281-284) against IL Synthesis reference instrument showed high correlation (r=0.9584-0.9988). iQM evaluation analyzed 79 cartridges with QC failures; Failure Pattern Recognition (FPR) detected 74/79 failures (93.7% detection) with zero false positives. Field evaluation (304 samples) demonstrated iQM successfully detected and flagged transient drift/interference (Benzalkonium, Thiopental Sodium) that went undetected by external controls.
Technological Characteristics
Portable whole blood analyzer; uses disposable cartridges. iQM system performs continuous automated monitoring. Connectivity: standalone. Software-based quality control replaces manual external controls. Calibration verified via GEM CVP (4 levels).
Indications for Use
Indicated for use by healthcare professionals for rapid analysis of whole blood samples (pH, blood gases, electrolytes, metabolites, hematocrit) in clinical settings.

### Summary of performance data (Cont.):
### GEM® Premier 3000 with iQM™ Method Comparison
In addition, a method comparison study was performed to verify the performance of the GEM® Premier 3000 cartridge with iQM" (Intelligent Quality Management). The method comparison data included arterial, venous, heart bypass and liver transplant blood samples from hospital patients using heparinized syringes. All samples were analyzed on the GEM® Premier 3000 with iQM versus an IL Synthesis as the reference instrument. The GEM® Premier 3000 with iQM " was shown to be statistically similar to the reference instrument:
| Analyte | N | Slope | Intercept | r | Sample Range |
|------------------|-----|--------|-----------|--------|--------------|
| pH | 281 | 1.0802 | -0.5810 | 0.9917 | 7.129-7.559 |
| pCO2 (mmHg) | 282 | 1.0674 | -2.3800 | 0.9839 | 25.3-87.5 |
| pO2 (mmHg) | 282 | 0.9715 | 6.9900 | 0.9988 | 26-489 |

### iQM™ (Intelligent Quality Management) Evaluation
#### Evaluation of Cartridge Malfunction Detection .
Data from 79 GEM® Premier 3000 cartridges that demonstrated a QC failure during their cartridge use life were extensively analyzed. The Failure Pattern Recognition (FPR) checks were applied to these data to determine if iQM" could detect any malfunction.
The Failure Pattern Recognition (FPR) checks were able to detect malfunction in 74 out of 79 reported QC failures. In most cases, iQM" would have flagged the failure immediately after the sample that caused the malfunction, while with conventional controls, the user would only be aware of a problem when the external control is run again, which may be up to hours after the event occurred. Furthermore, no false positive flags were generated by the FPR checks in any of the 79 investigated cartridges.
### Resolution of 5 Unflagged QC Failures:
For the 5 reported QC failures that iQM" did not detect, there was no identifiable cartridge malfunction. All system parameters were within specifications. There were no error flags and no failure patterns. There were no unusual blood values for the parameter with reported QC failure and the customer did not report any concern about blood results. In all five cases, the reported QC failures were marginal and at one level only. It was concluded that the reported QC failures in these five cartridges could not represent a serious cartridge malfunction. The failures could be considered as a false positive QC failure.

# Section 3 (Cont.) GEM® Premier 3000: Introduction of iQM™ and GEM® CVP 510(k) Summary (Summary of Safety and Effectiveness)
### Field Evaluation: External QC vs. iQM™
During an external field evaluation at a U.S. hospital, a side-by-side comparison was performed on a GEM® Premier 3000 using iQM™ versus two reference instruments, IL Synthesis and GEM® 3000 without iQM using traditional external quality controls. This study was conducted over a 3-week period with the external quality controls run during each day's shift: contrIL" 9 on all three analyzers and GEM® critCheck on the GEM® analyzers only. Each GEM® instrument used a single 450 sample capacity cartridge (1 instrument with and 1 instrument without iQM"). A total number of 304 blood samples were tested.
During this field evaluation, there were no instances of external failure on any instrument. However, the instruments experienced transient drift failures caused by interference as noted below:
- . There were 4 instances of Benzalkonium exposure, which caused analyte failures on all three instruments.
- . There were 8 instances of Thiopental Sodium* exposure, which caused analyte failures on both the GEM® instruments, with and without iQM™.
*NOTE: The IL Synthesis is not affected by Thiopental Sodium.
In all of the above cases, the GEM® Premier 3000 using iQM™ successfully detected and flagged the failed analytes and identified the cause as interference. All three systems self-corrected by the next sample run and therefore, the interference went undetected by external quality controls.

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.
