## Indications for Use

The T3 Calibrator is intended for use in the calibration of Total Triiodothyronine (T3) method on the Dimension® clinical chemistry system with the Heterogeneous Immunoassay Module.

## Device Story

The Dimension® Total Triiodothyronine (T3) Calibrator (RC414) is a liquid, multi-level calibrator kit consisting of 10 vials (two each at five levels). Level 1 contains stripped human serum; levels 2-5 contain L-triiodothyronine in a stripped human serum base. The device is used in a clinical laboratory setting to calibrate the T3 assay on the Dimension® clinical chemistry system equipped with a Heterogeneous Immunoassay Module. By establishing a calibration curve, the device enables the system to accurately quantify T3 concentrations in patient samples, supporting clinical diagnostic decision-making regarding thyroid function.

## Clinical Evidence

bench testing only

## Technological Characteristics

Liquid calibrator kit; 5 levels (0, 1, 2, 4, 6.5 ng/mL); matrix: stripped human serum base; analyte: L-triiodothyronine. Designed for use with Dimension® clinical chemistry system Heterogeneous Immunoassay Module.

## 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.

## Predicate Devices

- Opus Total T3 Calibrator ([K953160](/device/K953160.md))
