The summary describes a fluorescent immunoassay for quantitative determination of a substance in serum/plasma. There is no mention of AI, ML, image processing, or any other technology typically associated with AI/ML in the device description, intended use, or performance studies. The performance study focuses on correlation with another assay, not on AI/ML-driven metrics.
No.
The device is an immunoassay for the quantitative determination of free triiodothyronine in human serum or plasma, which is a diagnostic function, not a therapeutic one.
Yes.
The device is used for the "quantitative determination of free triiodothyronine assay in human serum or plasma," which is a measurement used to aid in diagnosis.
No
The device description explicitly states "Fluorescent immunoassay reagents," indicating it is a physical reagent kit, not a software-only device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use/Indications for Use: The description explicitly states it's for the "quantitative determination of free triiodothyronine assay in human serum or plasma." This is a classic definition of an in vitro diagnostic test, as it analyzes biological samples (serum or plasma) outside of the body to diagnose or monitor a condition (related to thyroid function, as triiodothyronine is a thyroid hormone).
- Device Description: "Fluorescent immunoassay reagents" are components used in an in vitro diagnostic test.
- Anatomical Site: "Not Applicable (In vitro diagnostic)" further confirms its nature as a test performed on samples outside the body.
The information provided clearly indicates that the AuraFlex® FT3 assay is designed to be used in a laboratory setting to analyze human biological samples for diagnostic purposes, which is the definition of an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The AuraFlex® FT3 assay is a fluorescent immunoassay for the quantitative determination of free triiodothyronine assay in human serum or plasma using the AuraFlex® System. AuraFlex FT3 employs a fluorescent enzyme immunometric assay technology for the quantitative determination of free triodothyronine (FT-) in human serum or plasma using the AuraFlex system.

Summary of Performance Studies
A comparison study was conducted in which 110 human serum samples were assayed using the AuraFlex® FT3 assay in singlicate. Results between the two assays showed a correlation of 0.9 (AuraFlex* FT3 = 0.93 Other FT3 assay +0.2pg/ml (0.3 pmoV1).

Dear Mr. Taylor:
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 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. Existinq major regulations affecting your device can be found in the Code of Federal Requlations, Title 21, Parts 800 to 895. ದ 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 Druq Administration (FDA) will verify such assumptions.
