The summary describes a standard immunoassay system and reagents for measuring Free T3. There is no mention of AI or ML in the intended use, device description, or performance studies.
No
This device is for in vitro diagnostic use, specifically for measuring Free T3 concentrations to aid in the diagnosis of thyroid disease, not for treating it.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device "quantitatively measures free triodothyronine (FT3) concentration in serum and plasma... to aid in the differential diagnosis of thyroid disease." This directly aligns with the definition of a diagnostic device.
No
The device description explicitly details hardware components (VITROS Immunodiagnostic System instrumentation, coated microwells) and reagents, indicating it is not a software-only device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use/Indications for Use: The document explicitly states "For in vitro diagnostic use only" for both the Reagent Pack and the Calibrators. It also describes the purpose of the device as measuring Free T3 concentration in serum and plasma "to aid in the differential diagnosis of thyroid disease." This clearly indicates the device is intended for use outside of the body to diagnose a medical condition.
- Device Description: The description details a system that uses reagents and instrumentation to perform quantitative measurements of analytes in human body fluids (serum and plasma). This aligns with the definition of an in vitro diagnostic device.

Device Description
The VITROS Immunodiagnostic System uses luminescence as the signal in the quantitative and semi-quantitative determination of selected analytes in human body fluids, commonly serum and plasma. Coated microwells are used as the solid phase separation system.
The system is comprised of three main elements:
-
- The VITROS Immunodiagnostic Products range of immunoassay products (in this case VITROS Immunodiagnostic Products Free T3 Reagent Pack, VITROS Immunodiagnostic Products Free T3 Calibrators, which are combined by the VITROS Immunodiagnostic System to perform the VITROS Free T3 assay.
-
- The VITROS Immunodiagnostic System instrumentation, which provides automated use of the immunoassay kits. The VITROS Immunodiagnostic System was cleared for market by a separate 510(k) pre-market notification (K962919).
-
- Common reagents used by the VITROS System in each assay. The VITROS Immunodiagnostic Products Signal Reagent and VITROS Immunodiagnostic Products Universal Wash Reagent were cleared as part of the VITROS Immunodiagnostic Products Total T3 Reagent Pack and VITROS Immunodiagnostic Products Total T3 Calibrators 510(k) premarket notification (K964310).
The VITROS System and common reagents are dedicated specifically for use only with the VITROS Immunodiagnostic Products range of immunoassay products.

Dear Ms. Shulman:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we 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). 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 (Premarket Approval), 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 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

Under the Clinical Laboratory Improvement Amendments of 1988 (CLIA-88), this device may require a CLIA complexity categorization. To determine if it does, you should contact the Centers for Disease Control and Prevention (CDC) at (770) 488-7655.
This letter will allow you to begin marketing your device as described in your 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 Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4588. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639.
