## Indications for Use

The ST AIA-PACK hsE2 Calibrator Set is intended for In Vitro Diagnostic Use Only for the calibration of the ST AIA-PACK hsE2 assay.

## Device Story

ST AIA-PACK hsE2 Calibrator Set consists of six liquid levels of human serum containing estradiol (0 to 1,100 pg/mL) and sodium azide preservative. Used on Tosoh AIA System Analyzers to calibrate the hsE2 assay. Calibrators are processed by the analyzer to establish a calibration curve, allowing the system to quantify estradiol concentrations in patient serum or heparinized plasma samples. Used by laboratory technicians in clinical settings. Output is a calibration curve used to calculate patient results, aiding clinicians in diagnosing and monitoring conditions related to estradiol levels.

## Clinical Evidence

Bench testing only. Stability studies (real-time and open-vial) confirmed 12-month shelf life and 1-day open-vial stability at 2-8°C. Value assignment validation demonstrated grand mean recovery within 10% CV across multiple analyzers and reagent lots.

## Technological Characteristics

Liquid calibrator set; human serum matrix with sodium azide preservative. Six levels (0, 25, 50, 100, 500, 1100 pg/mL). Traceable to IRMM CRM577. Designed for use on Tosoh AIA System Analyzers. Refrigerated 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.
