Device Description

Architect Total ß-hCG MasterCheck Level 0 contains HEPES buffer with protein (bovine) stabilizers. Architect Total ß-hCG MasterCheck Levels 1, 2, 3 and 4 contain ß-hCG (human) prepared in HEPES buffer with protein (bovine) stabilizers. Preservative: Antimicrobial agent.

AI/ML Overview

This document is a 510(k) summary for the Architect Total ß-hCG MasterCheck, a control device used for verifying sensitivity, calibration linearity, and reportable range on the Abbott Architect i System. As a control product, the document does not contain information about clinical studies with human participants or an AI device. Therefore, many of the requested categories related to clinical studies are not applicable.

Here's a breakdown of the available information:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly state "acceptance criteria" in a quantitative table format as would be seen for a diagnostic or therapeutic device. Instead, it focuses on the intended use and technological characteristics for substantial equivalence to a predicate device. The performance is implied by its intended use for "verification of sensitivity, calibration linearity, and reportable range."

Feature/Characteristic	Architect Total ß-hCG MasterCheck (Reported Performance)	Casco Standards Document Serum Multi-Analyte Verification Test Set (Predicate Device)
Intended Use	Verification of sensitivity, calibration linearity, and reportable range on the Abbott Architect i System.	In vitro diagnostic use in the quantitative determination of linearity, calibration verification and verification of reportable range using automated, semi-automated and manual methods.
Form	Liquid	Liquid
Matrix	HEPES buffer with protein (bovine) stabilizers	Human Serum
Storage	2-8°C	-10 to -20°C
Analytes	Total ß-hCG	Multiple
Open Vial Claim	3 Days at 2-8°C	30 Days at 2-8°C
Differences	Calibration verifier for the Architect Total ß-hCG assay	Calibration verifier for multiple analytes

2. Sample size used for the test set and the data provenance

Not applicable. This is a control product, not a diagnostic device involving patient data. Performance is evaluated through laboratory testing of the control material itself, and the documentation does not specify a "test set" in the context of clinical data.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Not applicable. Ground truth for a control product is established through characterization of its known concentration, not expert consensus on patient cases.

4. Adjudication method for the test set

Not applicable. See point 3.

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

Not applicable. This is a control product, not an AI-powered diagnostic intended for human reader assistance.

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

Not applicable. This is a control product, not an algorithm.

7. The type of ground truth used

For a control product, the "ground truth" would be the assigned value (concentration) of the analyte (Total ß-hCG) within each level of the MasterCheck. This is established through rigorous analytical methods and calibration against primary standards. The document states that Levels 1, 2, 3, and 4 contain ß-hCG (human) prepared in HEPES buffer with protein stabilizers, implying these are spiked or manufactured to specific concentrations.

8. The sample size for the training set

Not applicable. This is a control product, not a machine learning model.

9. How the ground truth for the training set was established

Not applicable. See point 8.
