The document describes a standard in vitro diagnostic system and reagent cartridge for measuring Free Thyroxine. There is no mention of AI, ML, or any related technologies in the device description, intended use, or performance studies. The analysis relies on standard chemical and immunochemical methods.
No
The device is described as an "in vitro diagnostic device" that measures analytes for diagnosis and monitoring of diseases, not for treatment.
Yes
The "Intended Use / Indications for Use" section explicitly states, "The Dimension® EXL™ with LM system is an in vitro diagnostic device" and "Measurements of free thyroxine are used in the diagnosis and monitoring of thyroid disease."
No
The device description clearly outlines a physical instrument system (Dimension® EXL™ with LM clinical chemistry system) and reagent cartridges (Dimension® FT4L Flex® reagent cartridge), which are hardware components. The software is part of the larger system, not a standalone software-only device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Explicit Statements: The document repeatedly states that the components are "in vitro diagnostic" devices.
- "The FT4L method is an in vitro diagnostic test..."
- "The LOCI® Thyroid Calibrator is an in vitro diagnostic product..."
- "The Dimension® EXL™ with LM system is an in vitro diagnostic device..."
- "The Dimension® FT4L Flex® reagent cartridge is an in vitro diagnostic device..."
- Intended Use: The intended use is to measure analytes in human serum and plasma for the diagnosis and monitoring of thyroid disease. This is a classic definition of an in vitro diagnostic test.
- Device Description: The description details a system designed to analyze human body fluids using various chemical and immunochemical methods, which aligns with the function of an IVD.
- Performance Studies: The performance studies describe method comparison using human serum samples, further supporting its use in a clinical diagnostic setting.
Therefore, based on the provided information, the device is clearly identified and described as an In Vitro Diagnostic.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Method comparison studies were conducted on the Dimension® FT4L Flex® vs. the Dimension® Vista FT4 Flex® reagent cartridge using one hundred-and-eighty (180) serum samples. The data was analyzed using least squares linear regression. The Dimension® FT4L Flex® demonstrated excellent correlation to the predicate device as evidenced by a correlation coefficient = 0.999.

§ 862.1695 Free thyroxine test system.
(a)
Identification. A free thyroxine test system is a device intended to measure free (not protein bound) thyroxine (thyroid hormone) in serum or plasma. Levels of free thyroxine in plasma are thought to reflect the amount of thyroxine hormone available to the cells and may therefore determine the clinical metabolic status of thyroxine. Measurements obtained by this device are used in the diagnosis and treatment of thyroid diseases.(b)
Classification. Class II.
