## Indications for Use

The Elecsys proBNP II CalCheck 5 is an assayed control for use in calibration verification and for use in the verification of the assay range established by the Elecsys proBNP II reagent on the indicated Elecsys and cobas e immunoassay analyzers. For prescription use only. The Elecsys proBNP II CalCheck is not intended to be used as a primary calibrator or routine control material.

## Device Story

Elecsys proBNP II CalCheck 5 is a lyophilized, assayed quality control material; consists of NT-proBNP (1-76) amide spiked into human serum and potassium phosphate buffered matrix. Used in clinical laboratory settings by laboratory professionals to verify calibration and assay range of Elecsys proBNP II reagent on Elecsys and cobas e immunoassay analyzers. Product requires reconstitution with distilled or deionized water before use. Provides five concentration levels to support expanded range verification compared to the three-level predicate. Helps ensure accuracy and reliability of proBNP immunoassay results, supporting clinical decision-making for cardiac conditions.

## Clinical Evidence

No clinical data. Bench testing only. Stability testing (real-time and accelerated) confirmed shelf-life and reconstituted stability. Value assignment performed using multiple Elecsys/cobas e analyzer systems to establish target values.

## Technological Characteristics

Lyophilized synthetic NT-proBNP in human serum/buffer matrix. Five levels. Storage: 2-8°C unopened; 4 hours at 20-25°C reconstituted. Compatible with Elecsys 2010/cobas e411 and MODULAR ANALYTICS E 170/cobas e 601 systems.

## Regulatory Identification

A quality control material (assayed and unassayed) for clinical chemistry is a device intended for medical purposes for use in a test system to estimate test precision and to detect systematic analytical deviations that may arise from reagent or analytical instrument variation. A quality control material (assayed and unassayed) may be used for proficiency testing in interlaboratory surveys. This generic type of device includes controls (assayed and unassayed) for blood gases, electrolytes, enzymes, multianalytes (all kinds), single (specified) analytes, or urinalysis controls.

## Traceability and Value Assignment

The assayed value of each CalCheck level was standardized against reference standards by weighing pure synthetic NT-proBNP (1-76) amide into a human serum matrix.

Value assignment is performed for each Elecsys proBNP II CalCheck5 lot. Values are assigned for each lot of proBNP II CalCheck 5 in combination with each Elecsys proBNP II reagent lot available. Values are assigned using four Elecsys MODULAR ANALYTICS E170/cobas e601 analyzers and three Elecsys 2010/cobas e411 analyzers. Each sample is tested in duplicate. The target value for each CalCheck is the median of the observed values.

The labeling states that laboratories should establish appropriate acceptance criteria when using this product for its intended use.

## Stability

Real time and accelerated stability testing protocols and acceptance criteria were described and found to be adequate. CalCheck 5 is stable until the expiration date printed on the vial when stored unopened at $2 - 8^{\circ}\mathrm{C}$. The reconstituted vials are stable for four hours at $20 - 25^{\circ}\mathrm{C}$.
