No
The description details a standard immunoassay based on electrochemiluminescence and a calibration curve, with no mention of AI or ML algorithms for data analysis or interpretation.
No.
This device is an in vitro diagnostic immunoassay used to aid in the diagnosis of autoimmune thyroid diseases by quantitatively determining antibodies, not to treat a condition.
Yes
The device is described as "an aid in the diagnosis of autoimmune thyroid diseases," indicating its use in determining a medical condition.
No
The device description clearly outlines a system based on a competitive immunoassay with streptavidin microparticles and electrochemiluminescence detection, which are physical components and processes, not solely software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The "Intended Use / Indications for Use" section explicitly states that the Elecsys Anti-TPO immunoassay is "for the in vitro quantitative determination of antibodies to thyroid peroxidase in human serum and plasma." The phrase "in vitro" is a key indicator of an IVD.
- Purpose: The intended use also states that the determination is used "as an aid in the diagnosis of autoimmune thyroid diseases." This indicates the device is used to analyze samples taken from the human body to provide information for diagnostic purposes.
- Sample Type: The device analyzes "human serum and plasma," which are biological samples taken from a patient.
- Technology: The "Device Description" describes an "electrochemiluminescence immunoassay," which is a common technology used in IVD tests to detect and measure substances in biological samples.
All of these points align with the definition of an In Vitro Diagnostic device.

Device Description
The COBAS Elecsys® Anti-TPO Test System is based on a competitive immunoassay with streptavidin microparticles and electrochemiluminescence detection. First and second incubations are nine minutes in duration. The reaction mixture is aspirated into the measuring cell where the microparticles are magnetically captured onto the surface of the electrode, unbound substances are removed. Voltage is applied to the electrode inducing chemiluminescent emission which is measured by a photomultiplier. Results are determined using a calibration curve that is generated specifically on each instrument by a 2 point calibration and a master curve provided with the reagent bar code.

§ 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).

Dear Ms. Taylor:
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, listing 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 the Code of Federal Regulations, Title 21, Parts 800 to 898. 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 Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
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 legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
