No
The summary describes an ELISA assay kit, which is a laboratory test method, and there is no mention of AI or ML in the provided text.

No.
The device is an in vitro diagnostic assay used to aid in the diagnosis of a disease, not to treat or alleviate a disease.

Yes
The "Intended Use / Indications for Use" states that the assay is "useful as an aid in the diagnosis of Graves' Disease."

No

The device is an ELISA assay kit, which is a laboratory test kit containing reagents and other physical components, not a software-only device.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use explicitly states it's for the "semi-quantitative determination of antibodies to the thyroid stimulating hormone receptor in human serum." This involves testing a sample taken from the human body (serum) in vitro (outside the body) to gain information about a medical condition (Graves' Disease).
  • Sample Type: It uses "human serum," which is a biological sample taken from a patient.
  • Purpose: It's used as an "aid in the diagnosis of Graves' Disease," which is a medical condition.

These are all key characteristics of an In Vitro Diagnostic device.

§ 866.5870 Thyroid autoantibody immunological test system.

(a)
Identification. A thyroid autoantibody immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the thyroid autoantibodies (antibodies produced against the body's own tissues). Measurement of thyroid autoantibodies may aid in the diagnosis of certain thyroid disorders, such as Hashimoto's disease (chronic lymphocytic thyroiditis), nontoxic goiter (enlargement of thyroid gland), Grave's disease (enlargement of the thyroid gland with protrusion of the eyeballs), and cancer of the thyroid.(b)
Classification. Class II (performance standards).
