## Indications for Use

The ST AIA-PACK C-Peptide II Calibrator Set is intended for In Vitro Diagnostic Use Only for the calibration of the ST AIA-PACK C-Peptide II assay.

## Device Story

The ST AIA-PACK C-Peptide II Calibrator Set consists of six levels of calibrators (0 to 33 ng/mL) used to calibrate the ST AIA-PACK C-Peptide II assay on Tosoh AIA System analyzers. The set includes one liquid calibrator (0 ng/mL) and five lyophilized calibrators containing C-peptide in a protein matrix with sucrose. The device is used in clinical laboratory settings by trained laboratory personnel. The healthcare provider uses the calibrated assay to measure C-peptide levels in patient samples (urine, serum, EDTA plasma), which aids in clinical decision-making regarding insulin production and diabetes management. The calibrators are standardized against WHO 1st IRP 84/510 to ensure accurate assay performance.

## Clinical Evidence

Bench testing only. Stability studies confirmed a 12-month shelf life at 2-8°C and a 1-day in-use stability after reconstitution. Recovery and reproducibility (CV <= 10%) met acceptance criteria (100 +/- 10%) across three lots.

## Technological Characteristics

Six-level calibrator set; protein matrix with sucrose; lyophilized (levels 2-6) and liquid (level 1) formats; sodium azide preservative. Standardized against WHO 1st IRP 84/510. Designed for use on Tosoh AIA System analyzers. Storage: 2-8°C.

## Regulatory Identification

A calibrator is a device intended for medical purposes for use in a test system to establish points of reference that are used in the determination of values in the measurement of substances in human specimens. (See also § 862.2 in this part.)

## Special Controls

*Classification.* Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 862.9.
