The summary describes an enzyme immunoassay for detecting antibodies, which is a standard laboratory technique and does not mention any AI/ML components or related concepts like image processing, training/test sets, or performance metrics typically associated with AI/ML devices.
No
This device is an immunoassay for detecting antibodies, intended as an aid in diagnosis, not for treating any condition.
Yes
The device is described as an "aid in the diagnosis of autoimmune thyroid disorders," which directly indicates its diagnostic purpose.
No
The device is described as an "enzyme immunoassay," which is a laboratory test method involving chemical reagents and physical processes, not solely software. The description of detecting antibodies in human serum further indicates a physical laboratory component.
Yes, based on the provided information, the TheraTest EL-Anti-TPO™ and TheraTest EL-Anti-Thyroglobulin™ devices are IVDs (In Vitro Diagnostics).
Here's why:
- Intended Use: The intended use explicitly states that these devices are enzyme immunoassays for the detection or determination of antibodies in human serum. Serum is a biological sample taken in vitro (outside the body).
- Purpose: The purpose is to aid in the diagnosis of autoimmune thyroid disorders, which is a diagnostic purpose.
- Method: Enzyme immunoassay is a laboratory technique performed in vitro.
The definition of an IVD generally includes reagents, instruments, and systems intended for use in the diagnosis of disease or other conditions, including a determination of the state of health, in order to cure, mitigate, treat, or prevent disease or its sequelae. These devices clearly fit this description by analyzing a human sample in vitro to aid in diagnosis.

§ 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).

Trade/Device Name: TheraTest EL-Anti-TPO™ and TheraTest EL-Anti-Thyroglobulin™ Regulation Number: 21 CFR 866.5870 Regulation name: Thyroid Autoantibody Immunological Test System Regulatory Class: Class II Product Code: JZO Dated: August 4, 2009 Received: August 7, 2009
Dear Dr. Lakos:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not-require approval of a premarket approval application (PMA), You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration. Ilsting of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); medical device reporting (reporting of

medical device-related adverse events) (21 CFR 803); and good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820). This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Parts 801 and 809), please contact the Office of In Vitro Diagnostic Device Evaluation and Safety at (301) 796-5450. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to
