## Indications for Use

The Elecsys HCG+β 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 HCG+β reagent on the indicated Elecsys and cobas e immunoassay analyzers.

## Device Story

Elecsys HCG+β CalCheck 5 is a lyophilized, assayed quality control material consisting of HCG in a human serum matrix; used in clinical laboratory settings to verify calibration and reportable range of Elecsys HCG+β reagent on Elecsys and cobas e immunoassay analyzers. Product is reconstituted with distilled or deionized water by laboratory personnel. Provides five concentration levels to ensure analytical performance across the assay range. Benefits patient care by ensuring accuracy and reliability of HCG immunoassay results used for diagnostic testing.

## 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 2010/cobas e411 and MODULAR ANALYTICS E140/cobas e 601 analyzers, with target values determined as the median of duplicate measurements.

## Technological Characteristics

Lyophilized human serum matrix; five concentration levels; reconstituted with distilled or deionized water; stored at 2-8°C unopened; stability 4 hours at 20-25°C after reconstitution. No electronic or software components.

## 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.

# I. Device Description:

The Elecsys HCG+β CalCheck 5 is a lyophilized product consisting of human chorionic gonadotropin (hCG) purified from human urine in human serum matrix. During manufacture, the hCG is spiked into the matrix at the target concentrations listed below. CalCheck Level 1 contains no analyte.

|  Elecsys HCG+β CalCheck level | Target Value (mIU/mL)  |
| --- | --- |
|  Level 1 | ≤0.2  |
|  Level 2 | 5  |
|  Level 3 | 5,000  |
|  Level 4 | 8,000  |
|  Level 5 | 10,000  |

The human source materials were prepared exclusively from the blood of donors tested individually and shown to be free from HBsAg and antibodies to HCV and HIV. The testing methods applied were FDA-approved or cleared in compliance with the European Directive 98/79/EC, Annex II, List A.
