Intended Use

AMY7 reagent, in conjunction with SYNCHRON® System(s) and UniCel® DxC System(s), is intended for the quantitative determination of total Amylase activity in human serum, plasma or urine.

Amylase measurements are used primarily in the diagnosis and treatment of pancreatitis.

Device Description

AMY7 reagent is used to measure the amylase activity by an enzymatic rate method. The system monitors the change in absorbance at 410 nanometers. This change in absorbance is directly proportional to the activity of AMY7 in the sample and is used by the System to calculate and express the total AMY7 activity.

The SYNCHRON G7 Amylase (AMY7) Reagent is designed for optimal performance on the SYNCHRON LX®, UniCel® DxC 600/800, and SYNCHRON CX® PRO Clinical Systems. The reagent kit contains two 200-test cartridges.

AI/ML Overview

Acceptance Criteria and Device Performance for SYNCHRON® Systems G7 Amylase (AMY7) Reagent

This document describes the acceptance criteria and study proving the SYNCHRON® Systems G7 Amylase (AMY7) Reagent meets these criteria, based on the provided FDA 510(k) submission (K091846).

1. Table of Acceptance Criteria and Reported Device Performance

The provided document doesn't explicitly state "acceptance criteria" with numerical thresholds. Instead, it demonstrates substantial equivalence to a predicate device through various performance studies. The implicit acceptance criterion is that the candidate device's performance should be comparable to or better than the predicate device across critical metrics.

Based on the summary of performance data, the following table outlines the reported device performance for different studies. The "Acceptance Criteria" column reflects the implicit expectation for a new device to perform comparably to or better than the predicate.

The study details that "Equivalence is demonstrated through method comparison, stability, linearity, and imprecision experiments." The provided results for method comparison and precision support this claim by showing strong correlation coefficients and low coefficients of variation, indicating the device performs comparably to the predicate.

2. Sample Size Used for the Test Set and Data Provenance

The document refers to "test sets" in the context of method comparison and precision studies.

  • Method Comparison Studies (Test Set Sample Sizes):
    • Serum: N=87 (on CX7 PRO), N=83 (on DxC 600)
    • Urine: N=78 (on CX7 PRO), N=78 (on DxC 600)
  • Precision Studies (Test Set and Measurement Sample Sizes):
    • Each of the 12 precision measurements (e.g., Within-Run Serum/Plasma Level 1 on CX7 PRO) was based on N=80 measurements. This means 80 individual readings or replicates were taken for each specific sample level/type/imprecision category on each platform.
  • Data Provenance: The document does not specify the country of origin of the data or whether the data was retrospective or prospective.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

This section is not applicable to this type of device. The SYNCHRON® Systems G7 Amylase (AMY7) Reagent is an in-vitro diagnostic assay for quantitative determination of amylase activity. The "ground truth" for such devices is typically established by comparing its measurements against a legally marketed predicate device (as done here) or against a recognized reference method, rather than through expert consensus on qualitative interpretation (like in imaging diagnostics). Therefore, no human experts were involved in establishing the ground truth for the test set in the way described.

4. Adjudication Method for the Test Set

This section is not applicable for the same reasons as point 3. No human adjudication was involved as the ground truth is based on quantitative measurements and comparison to a predicate device.

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 section is not applicable. This device is an automated in-vitro diagnostic reagent and does not involve "human readers" or "AI assistance" in the context of interpretation or a MRMC study.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

This describes the nature of the device: it is a standalone automated assay. The performance data presented (method comparison, precision) reflects the algorithm's (reagent's) performance without human intervention in the measurement process after sample loading. The results are generated directly by the SYNCHRON® System(s) and UniCel® DxC System(s).

7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.)

The ground truth for this device is established by comparison to a legally marketed predicate device (Thermo Fisher Scientific, Inc. Amylase EPS Reagent, K070064) using method comparison studies. This type of comparison demonstrates that the new device provides results that are substantially equivalent to a device already cleared by the FDA, implying that its measurements are generally accepted as accurate and reliable for the intended use. In addition, the device's inherent precision (reproducibility of results) is also assessed and forms part of its validated performance.

8. The Sample Size for the Training Set

The document does not provide details about a "training set" in the context of machine learning or AI models. For an IVD reagent, development and validation typically involve:

  1. Reagent formulation and optimization: This involves experiments to define the optimal concentrations of components, reaction times, etc., using various samples, analogous to a training phase by trial and error in product development.
  2. Verification studies (linearity, interference, etc.): These use various prepared samples to ensure the assay performs as expected.
  3. Validation studies (method comparison, precision, stability): These studies, as detailed in the document, use human biological samples to demonstrate performance against established methods.

The document directly presents validation study results. It does not separate data into distinct "training" and "test" sets in the machine learning sense, as the device is a chemical reagent, not an AI model.

9. How the Ground Truth for the Training Set Was Established

As noted in section 8, the concept of a "training set" with an associated ground truth in the AI context is not directly applicable here. The development and optimization of the reagent formulation implicitly involves establishing what constitutes an accurate amylase measurement (i.e., "ground truth") often through comparison to known standards, reference methods, or existing predicate devices during the development phase. However, the document does not detail this initial development process. The "ground truth" for the validation specified in this document is the performance of the predicate device.

Dear Ms. Boyajian:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
