## Indications for Use

The ARCHITECT Free T3 Calibrators are for the calibration of the ARCHITECT i System when used for the quantitative determination of free triiodothyronine (Free T3) in human serum and plasma.

## Device Story

ARCHITECT Free T3 Calibrators are liquid, ready-to-use human serum-based standards containing L-Thyroxine and L-Triiodothyronine; used to establish reference points for the ARCHITECT i System (i2000sr, i2000, i1000sr) during quantitative Free T3 assays. The kit consists of six levels (A-F) with concentrations ranging from 0.0 to 30.0 pg/mL. Calibrators are used by laboratory personnel in clinical settings to calibrate the assay system. By providing known concentrations, the device enables the system to generate a calibration curve, allowing for the accurate measurement of patient Free T3 levels. This measurement assists clinicians in assessing thyroid status. The device is stored at 2-8°C and is stable for 11-12 months.

## Clinical Evidence

Bench testing only. Stability studies were performed per CLSI EP25-A guidelines. Real-time stability (closed vial) and in-use stability (open vial) were evaluated over 11-12 months at 2-8°C. Results support the claimed shelf life and in-use stability.

## Technological Characteristics

Human serum-based calibrators; preservative: sodium azide. Six-level concentration range (0.0 to 30.0 pg/mL). Standardization via gravimetric methods using L-Triiodothyronine and L-Thyroxine (USP grade, >95% purity). Compatible with ARCHITECT i System. Storage: 2-8°C. Ready-to-use liquid form factor.

## 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.
