## Indications for Use

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

## Device Story

ST AIA-PACK PROG III Calibrator Set consists of six liquid levels of bovine protein matrix containing progesterone (0 to 45 ng/mL approx.) and sodium azide preservative. Used in clinical laboratories on Tosoh AIA System Analyzers to calibrate the ST AIA-PACK PROG III assay. Calibrator values are assigned gravimetrically using USP reference standards and verified on AIA-2000 instruments. Healthcare providers use the resulting assay calibration to quantify progesterone levels in patient serum or heparinized plasma samples. Accurate calibration ensures the assay provides reliable progesterone measurements, which aids clinicians in assessing reproductive health and endocrine function.

## Clinical Evidence

Bench testing only. Stability studies (real-time and open-vial) confirmed recovery within 100 +/- 10% and reproducibility (CV) <= 10%. Value assignment was validated by analyzing 5 replicates on two Tosoh AIA-2000 instruments, demonstrating precision (CV) between 2.0% and 4.8% across calibrator levels.

## Technological Characteristics

Liquid calibrator set; bovine protein matrix; sodium azide preservative. Six levels (0, 0.5, 1.5, 5.0, 15, 45 ng/mL). Traceable to USP reference standard (Lot #11J239). 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.
