The description details a standard immunoassay using flow cytometry and dedicated software for data analysis and calculation, with no mention of AI or ML algorithms.
No.
The device is an in vitro diagnostic (IVD) kit used for the detection of antibodies as an aid in the diagnosis of auto-immune thyroid pathologies. It is not designed for treatment or therapy.
Yes
The "Intended Use / Indications for Use" section explicitly states that "The test system is used on serum samples as an aid in the diagnostic of auto-immune thyroid pathologies".
No
The device description clearly outlines a system that includes physical components such as assay kits (vials, microspheres, reagents), a flow cytometer, an XYP platform, an analyzer, and a pump, in addition to the software. While software is part of the system, it is not the sole component.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states that the kit is "designed for the detection of antibodies directed against thyroperoxydase (TPO) and thyroglobuline (TG)" and is used on "serum samples as an aid in the diagnostic of auto-immune thyroid pathologies". This clearly indicates that the device is intended to be used in vitro (outside the body) to examine specimens (serum) from the human body to provide information for diagnostic purposes.
- Device Description: The description details the components of the kit, which are reagents and materials used to perform a test on a biological sample (serum). The process involves mixing patient sera with microspheres, adding conjugated antibodies, and analyzing the reaction using a flow cytometer. This is a typical workflow for an in vitro diagnostic assay.
- Clinical Utility: The clinical utility further reinforces the diagnostic purpose by stating it's used "in conjunction with clinical findings and other laboratory tests" for the diagnosis of auto-immune thyroid pathologies.
Based on the definition of an IVD, which is a medical device intended for use in vitro for the examination of specimens derived from the human body solely or principally for the purpose of providing information concerning a physiological or pathological state, the FIDIS™ THYRO kit fits this description.

Device Description
The assay kits consist of:
-
a vial of color-coded microsphercs coupled with thyroperoxydase (TPO) or thyroglobulin (TG)
-
a ready to use anti-human IgG coupled to phycocrythrin,
-
a ready to use calibrator titered for the specificity,
-
a positive control IgG to be diluted,
-
a negative control to be diluted,
-
a 10X concentrated PBS-Tween.
Rk: Calibrators, positive and negative controls are diluted human sera.
The FIDIS™ System is a fully integrated and automated system for immunodiagnostic testing.
FIDIS™ System comprised of FIDIS flow cytometer, XYP platform for automatic sampling into the analyser, the analyzer itself, a SD pump, some FIDIS™ kits and a software MLX-BOOSTER.
The FIDIS™ THYRO kit resembles traditional EIA and allows the detection and identification of antibodies against thyroperoxydase (TPO) and thyroglobuline (TG).
-
- Diluted patient sera and microsphere suspension are thoroughly mixed in the 96 well microtiter plate. TPO or TG specific antibodies in the patient sera, if present, bind to the immobilised antigen on the beads. Any unbound material is removed by performing a wash step.
-
- Phycoerythrin-conjugated goat anti-human IgG is added to the plate and a further incubation performed. The conjugated anti-human IgG binds to the TPO or TG specific antibodies immobilised on the microsphere surface to form an antigen/antibody complex.
-
- The bead suspension is then analysed by the FIDIS™ Instrument and reactions are directly calculated in biological units using specific data software (MLX-BOOSTER).
The FIDIS™ Instrument is able to distinguish the specific color-coded of the microsphere and it could associated the microsphere type with the individual tested antigen.
The FIDIS™ Instrument could quantify the fluorescence of the antibody captured by each microsphere. Measurement of the fluorescent signal from the final reaction complex allows the quantification of the presence or absence of autoantibodies.

§ 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).
