Immunoturbidmetric assay for the in vitro quantitative determination of apolipoprotein A-1 in human serum and plasma on automated clinical chemistry analyzers.
A lipoprotein test system is a device intended to measure lipoprotein in serum and plasma. Lipoprotein measurements are used in the diagnosis and treatment of lipid disorders and atherosclerosis.
A device for the measurement of human apolipoprotein A-1 in serum or plasma. Anti-apolipoprotein A-1 antibodies react with the antigen in the sample to form antigen/antibody complexes which, following agglutination, are measured turbidimetrically.
This document describes the Tina-quant Apolipoprotein A-1 ver.2 assay and its equivalence to a predicate device, but it does not detail a study with specific acceptance criteria that the device had to meet and prove. Instead, it describes a "substantial equivalence" comparison to an existing, legally marketed device.
Therefore, many of the requested sections (e.g., sample size for test set, number of experts, adjudication method, MRMC study, standalone performance, ground truth for test set, training set details) are not applicable or cannot be extracted from the provided text, as this type of information is typically associated with studies demonstrating performance against a defined statistical endpoint, not substantial equivalence.
Here's an analysis based on the provided text, focusing on the available information:
Description of Acceptance Criteria and the Study:
The "study" described in the provided text is a substantial equivalence comparison between the Tina-quant Apolipoprotein A-1 ver.2 assay and a predicate device (Dade Behring N Antisera to Human Apolipoprotein A-1 and Apolipoprotein B assay, K860894). The acceptance criteria for substantial equivalence are implicitly that the new device performs comparably to the predicate device across various characteristics, demonstrating similar safety and effectiveness.
The comparison focuses on:
- Intended Use and Indications for Use: Ensuring they are the same or very similar.
- Assay Protocol: Both are immunoturbidometric.
- Traceability/Standardization: The new device is standardized to IFCC reference preparation SP1-01.
- Calibration Interval: Similar.
- Performance Characteristics: Comparing precision, method comparison, hook effect, analytical sensitivity, and limitations.
The device meets the acceptance criteria by demonstrating performance characteristics that are comparable to or better than the predicate device, or within acceptable clinical ranges where direct comparison might not be feasible (e.g., analytical sensitivity).
1. Table of Acceptance Criteria and Reported Device Performance
Since this is a substantial equivalence claim, the "acceptance criteria" are implicitly the performance of the predicate device, and the "reported device performance" is how the new device compares. No explicit numerical acceptance criteria (e.g., "CV must be

Alpha -1-lipoprotein immunological test system.(a)
Identification. Analpha -1-lipoprotein immunological test system is a device that consists of the reagents used to measure by immunochemical techniques thealpha- 1-lipoprotein (high-density lipoprotein) in serum and plasma. Measurement ofalpha- 1-lipoprotein may aid in the diagnosis of Tangier disease (a hereditary disorder of fat metabolism).(b)
Classification. Class II (performance standards).
