## Indications for Use

The salivary progesterone calibrator is a device intended for medical purposes to use in the calibration of the Salimetrics progesterone immunoassay and to establish points of reference that are used to determine the concentration of free progesterone in saliva. The salivary progesterone controls are devices intended for use in monitoring the performance of the salivary immunoassay of free progesterone in saliva.

## Device Story

Salimetrics Progesterone Calibrator and Control are in vitro diagnostic reagents used to support salivary progesterone enzyme immunoassays. Calibrators establish reference points for quantification; controls monitor assay performance. Both are derived from synthetic progesterone suspended in a saliva-like matrix with non-mercury preservatives. Calibrators are provided in 1mL vials; controls are provided in 0.5mL vials at high (1000 pg/mL) and low (50.6 pg/mL) concentrations. Used in clinical or research laboratory settings by trained personnel. Output is used by healthcare providers to validate immunoassay results, ensuring accuracy in measuring free progesterone levels, which aids in clinical assessment of hormonal status.

## Clinical Evidence

No clinical data. Bench testing only. Stability studies (real-time and accelerated) confirm 1.5-year stability for calibrators and 2.0-year stability for controls. Traceability established via weighing on balances calibrated to international standards and NIST-validated pipettes. Performance verified via immunoassay.

## Technological Characteristics

Synthetic progesterone in saliva-like matrix; non-mercury preservative. Calibrator concentration: 2430 pg/mL; Control concentrations: 1000 pg/mL and 50.6 pg/mL. Requires microplate reader (450nm). Manufactured under GMP; balances/pipettes validated to NIST standards.

## 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.
