The Amylase2 assay is used for the quantitation of amylase in human serum, plasma, or urine on the ARCHITECT c System. The Amylase2 assay is to be used primarily as an aid in the diagnosis and treatment of pancreation of the pancreas).
The Amylase2 assay is an automated clinical chemistry assay. The Amylase2 assay is a two-part reaction. Ethylidene-4-NP-G7 (EPS) is hydrolyzed by a-amylase to form 4,6ethylidene-α-(1,4)-D-glucopyranosyl-Gx and 4-nitrophenyl-α-(1,4)-glucopyranosyl-G(7-x). The 4-nitrophenyl-a-(1,4)-glucopyranosyl-G(7-x) is then hydrolyzed into glucose monomers and the assay chromophore (4-nitrophenol) by a-glucosidase. The resulting change in absorbance at 404 nm is proportional to the a-amylase concentration in the sample. Methodology: Enzymatic/Colorimetric. The device is a reagent kit.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This information is not provided in the document. For an in-vitro diagnostic device, "ground truth" often refers to the true concentration of the analyte, which is usually established by highly precise reference methods, certified reference materials, or by comparison with a well-established predicate device, rather than expert consensus on images or clinical diagnoses. The document indicates standardization against IRMM/IFCC-456, which is a reference material for amylase, and comparison to a predicate device (AMY, K981653). These serve as the "ground truth" or reference for the device's performance.
4. Adjudication Method for the Test Set
This section is not applicable as this is an in-vitro diagnostic (IVD) device for quantitative measurement of amylase. Adjudication methods like "2+1" or "3+1" are typically used in clinical studies involving interpretation of medical images or subjective evaluations, where multiple experts independently assess data and discrepancies are resolved. For an IVD, the "ground truth" is measured quantitatively against a reference standard or predicate.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size of How Much Human Readers Improve with AI vs. Without AI Assistance
This information is not provided and is not applicable to this device. An Amylase2 assay is an automated clinical chemistry assay, not an AI-powered diagnostic imaging device that requires human "readers" or involves AI assistance in interpretation. Therefore, an MRMC study comparing human readers with and without AI assistance is not relevant to this product.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
The Amylase2 assay is an automated clinical chemistry assay, meaning its performance is inherently "standalone" in the sense that it provides a quantitative result without direct human intervention in the measurement process itself, beyond sample loading and general instrument operation. The studies described (precision, accuracy, linearity, interference, method comparison) are all evaluating the algorithm/reagent system's performance independently.
7. The Type of Ground Truth Used
The ground truth for the Amylase2 device's performance studies relies on:
- Reference Materials: For accuracy, the device was compared against "material standardized to the Certified Reference Material IRMM/IFCC-456."
- Predicate Device: For method comparison, the Amylase2 assay was compared to the predicate device, Amylase assay (List Number 7D58), which serves as the established reference standard in this context.
- Spiked Samples: For linearity, lower limits of measurement, interference, and dilution verification, samples were often "spiked" with known concentrations of α-amylase or interfering substances to create samples with a known "true" value.
- Commercial Controls: For precision and reproducibility studies, commercially available controls with known target ranges were used.
8. The Sample Size for the Training Set
The document describes studies for validation and verification purposes (test sets). For an IVD like Amylase2, the "training set" would refer to the data used by the manufacturer during the assay development phase to optimize reagents, calibrate the instrument response, and refine the measurement algorithms. This specific information about the development/training data size is not provided in the 510(k) summary, as the summary focuses on the performance of the final device.
9. How the Ground Truth for the Training Set Was Established
Similar to point 8, the specific details on how ground truth was established for any internal "training set" used during development are not provided. Typically, for such IVDs, this would involve a rigorous process of using purified analytes, gravimetric/volumetric standards, certified reference materials, and comparison to established reference methods to assign "true" values to a large panel of samples during the assay's development and optimization.

This product is to be used in a diagnostic laboratory setting, by qualified laboratory technologists, for the quantitative determination of amylase in human serum. It is intended for in vitro diagnostic use only. The determination of amylase in serum is most commonly performed for the diagnosis and treatment of diseases of the pancreas.
Not Found
The document provided is a premarket notification (510(k)) letter from the FDA to Pointe Scientific, Inc. regarding their Amylase EPS-G7 (Liquid) Reagent Set. This type of document declares "substantial equivalence" to a predicate device, which allows the product to be marketed, but does not typically include detailed studies proving performance against acceptance criteria in the way a clinical trial for a novel AI device would.
Therefore, many of the specific details requested in the prompt, such as sample sizes for test and training sets, expert qualifications for ground truth, adjudication methods, or MRMC studies, are not applicable to this 510(k) submission for an in vitro diagnostic reagent kit.
However, I can extract the relevant information about the device and its intended use, and explain why other sections are not present:
1. A table of acceptance criteria and the reported device performance
This document (a 510(k) clearance letter) does not typically contain a table of detailed performance characteristics and acceptance criteria in the way a clinical study report for an AI device might. For in-vitro diagnostic products like this, the demonstration of "substantial equivalence" to a legally marketed predicate device is the primary regulatory hurdle. This means the device is shown to perform as well as, or comparably to, an existing device on the market.
While the letter doesn't explicitly state "acceptance criteria," the intended performance of the device is for the "quantitative determination of amylase in human serum" for the "diagnosis and treatment of diseases of the pancreas." Substantial equivalence implies that its performance (e.g., sensitivity, specificity, accuracy, precision, linearity, interfering substances) is comparable to, and not worse than, the predicate device.
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
This information is not provided in the 510(k) clearance letter. For in vitro diagnostic reagents, performance studies are conducted, but their detailed results (including sample sizes, study design, and data provenance) are typically submitted to the FDA in a separate dossier and summarized or referenced in the 510(k) submission, rather than being fully reproduced in the publicly available clearance letter.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
This information is not applicable/provided in this context. For a reagent test determining a quantitative analyte (amylase), the "ground truth" is typically established by reference methods, standard assays, or certified reference materials, not by expert consensus in the way a diagnostic imaging interpretation would be.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This information is not applicable/provided. Adjudication methods are relevant for subjective interpretations (like radiology reads) where multiple experts might disagree. For quantitative assays, the "ground truth" is determined by objective laboratory measurements, not expert consensus requiring adjudication.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
This is not applicable. This device is a reagent set for laboratory testing, not an AI-assisted diagnostic tool that aids human readers. Therefore, an MRMC study comparing human performance with and without AI assistance is irrelevant.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This is not applicable. This is a laboratory reagent kit, not an algorithm. Its performance is inherent to the chemical reaction and analytical equipment, not an AI algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
For an amylase reagent test, the "ground truth" would typically be established through:
- Reference methods: Highly accurate and validated analytical methods.
- Standardized calibrators: Materials with known, certified concentrations of amylase.
- Interlaboratory comparisons: Performance against other established and trusted assays.
The specific type of ground truth used is not detailed in this 510(k) clearance letter.
8. The sample size for the training set
This information is not applicable/provided. This device is a chemical reagent, not a machine learning model, so there is no "training set" in the AI sense. Performance validation involves testing the reagent's characteristics (e.g., linearity, precision, accuracy, reproducibility) across a range of samples and conditions, but this is distinct from training an AI model.
9. How the ground truth for the training set was established
This information is not applicable/provided for the reasons stated in point 8.

The Amylase assay is used for the quantitation of amylase in serum, plasma, or urine on the AEROSET System. Amylase measurements are used primarily for the diagnosis and treatment of pancreatitis (inflammation of the pancreas).
Amylase is an in vitro diagnostic assay for the quantitative determination of amylase in serum, plasma, or urine. The Amylase assay is a clinical chemistry assay. The amylase in the sample hydrolyzes the 2-chloro-4-nitrophenyl-alpha-D-maltotrioside (CNPG3) to release 2-chloro-4-nitrophenol (CPNP) and form 2-chloro-4-nitrophenyl-alpha-D-maltoside (CNPG2), maltotriose (G3), and glucose (G). The rate of formation of the 2-chloro-4-nitrophenol is measured as an increase in the absorbance at 405 nm and is directly proportional to the activity of amylase present in the sample.
The Abbott Laboratories "Amylase" assay (Amy) is used for the quantitative determination of amylase in serum, plasma, or urine on the AEROSET System, primarily for the diagnosis and treatment of pancreatitis.
Here's a breakdown of its acceptance criteria and the study that proves its performance:
1. Table of Acceptance Criteria and Reported Device Performance
| Performance Characteristic | Acceptance Criteria (Implied by Predicate) | Reported Device Performance (Amy on AEROSET) |
|---|---|---|
| Correlation to Predicate (Serum) | Acceptable correlation with Boehringer Mannheim α-Amylase/EPS assay (K882225) on Hitachi 717 Analyzer | Correlation coefficient (r) = 0.9990, Slope = 1.237, Y-intercept = -1.232 U/L |
| Correlation to Predicate (Urine) | Acceptable correlation with Boehringer Mannheim α-Amylase/EPS assay (K882225) on Hitachi 717 Analyzer | Correlation coefficient (r) = 0.9963, Slope = 1.042, Y-intercept = 2.102 U/L |
| Precision (Serum, Level 1) | Not explicitly stated but implied to be low CV% | Total %CV for Level 1/Panel 101 = 1.0% |
| Precision (Serum, Level 2) | Not explicitly stated but implied to be low CV% | Total %CV for Level 2/Panel 102 = 1.6% |
| Precision (Urine, Level 1) | Not explicitly stated but implied to be low CV% | Total %CV for Level 1/Panel 201 = 1.3% |
| Precision (Urine, Level 2) | Not explicitly stated but implied to be low CV% | Total %CV for Level 2/Panel 202 = 1.1% |

Note: The document describes "acceptable correlation" as the acceptance criterion for the comparison studies. The specific numerical thresholds for correlation coefficient, slope, and intercept were not explicitly defined as acceptance criteria but are presented as the results that demonstrated "acceptable correlation" compared to the predicate device. Similarly, for precision, linearity, and sensitivity, specific acceptance criteria in terms of numerical ranges were not provided in the summary, but the reported performance values are presented as meeting the implied standard of "substantially equivalent" to the predicate.
2. Sample Size Used for the Test Set and Data Provenance
The document does not explicitly state the sample size used for the test set for the comparative performance studies or the precision studies.
The data provenance is not specified in terms of country of origin or whether it was retrospective or prospective. It states that "comparative performance studies were conducted" and "precision studies were conducted," implying these were experimental studies.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
Not applicable. This device is an in vitro diagnostic assay that quantifies amylase levels. The "ground truth" for the test set in this context would be the results obtained from the predicate device (Boehringer Mannheim α-Amylase/EPS assay on the Hitachi 717 Analyzer) against which the new device was compared. This is a comparison between two quantitative assays, not an expert-based diagnostic ground truth.
4. Adjudication Method for the Test Set
Not applicable, as the evaluation involves comparing quantitative results from two analytical devices, not adjudication by human experts.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and If So, What Was the Effect Size of How Much Human Readers Improve with AI vs. Without AI Assistance
Not applicable. This is an in vitro diagnostic assay, not an imaging device requiring human reader interpretation or an AI-assisted diagnostic tool.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
Yes, this is effectively a standalone performance evaluation. The "Amy" assay on the AEROSET System is an automated analytical system that quantitatively measures amylase. Its performance characteristics (correlation, precision, linearity, sensitivity) were evaluated directly, without human interpretation as part of the primary diagnostic output.
7. The Type of Ground Truth Used
The "ground truth" for the comparative effectiveness study (which establishes substantial equivalence) was the measurements obtained from the legally marketed predicate device: the Boehringer Mannheim α-Amylase/EPS assay (K882225) on the Hitachi 717 Analyzer.
8. The Sample Size for the Training Set
Not applicable. This is a classic in vitro diagnostic device, not a machine learning or AI-based algorithm that requires a "training set" in the computational sense. The device's calibration and method development would involve internal studies, but these are distinct from a "training set" for AI.
9. How the Ground Truth for the Training Set Was Established
Not applicable, for the same reason as point 8.
