The presence of these antibodies can be used in conjunction with clinical findings to aid in the diagnosis of Celiac disease. The FIDIS™ Celiac kit is to be used on serum only. FIDIS™ Celiac kits are to be used on FIDIS™ Analyser, software and washer. For in vitro diagnostic use.
Device Description
FIDISTM Celiac is based on Luminex 100TM Technology. The Luminex technology (LabMAP™, Laboratory Multi-Analyte Profiling) is a unique system I ho handler tooning of microspheres, flow cytometer, high speed digital signal processor and an X-Y platform for reading 96-well microtiter plates facilitating automated sample acquisition. This combination allows the diagnostic of multiple biological analytes simultaneously. This multiplexed microsphere-based flow cytometric assay involves fluorescent polystyrene microspheres. The antigen-coated microspheres are mixed and incubated with sample containing the analytes to be detected. A fluorochrome-conjugated detection molecule is subsequently incubated for analyte quantification. The flow cytometer is equipped with a powerful digital signal processor and two lasers. A red "classification" laser, excites fluorescent molecules intrinsic embedded to the microspheres and a green "reporter" laser, excites the extrinsic fluochrome (Phycoerythrin or Alexa-532nm) bound to the microsphere surface. During the sample reading, the flow cytometer analyzes individual microsphere, first, by size, and, second, by fluorescence emissions. Digital signal processors and computers algorithms provide simultaneous real-time acquisition of classification and reporter fluorescence signals output from the microspheres. Upon excitation, the emitted fluorescent signal from the microspheres travels through the optics paths to the individual detectors. According to the fluorescence ratio detected by the red laser, each microsphere is classified into on the basis of its unique fluorescence intensity which allows identifying which analyte is being tested. At the same time, the green "reporter" laser beam excites the external second molecule fluorescence to quantify the specific reaction related to each analyte. Each antigen required for the assay is covalently coupled to an individual set of microspheres through its surface functional groups. The different antigen coupled microspheres are mixed together to constitute the final microspheres reagent. Celiac IgA allows the detection of antigliadin and anti-tissue transglutaminase IgA isotype antibodies. Celiac IgG allows the detection of anti-gliadin IgG isotype antibodies. The test is performed in a 96 wells blank microplate including a filtering membrane at the bottom of the wells. In the first step, the sample is distributed in duplicate for the 2 isotypes (IgA and IgG) selected in each well containing respectively the Celiac A microspheres mixture, for the IgA isotype and the Celiac G microspheres mixture for the IgG isotype. After incubation, a wash step through a filtration process will eliminate the unbound antibodies. A specific conjugate consisting of either anti-human IgA or IgG antibodies coupled to phycoerythrin, is added to the mixture. It will bind to the previously captured antibodies. The reaction is then directly measured by the flow cytometer, which categorizes each microspheres set according to its fluorescence colour the microspheres while simultaneously measuring the average fluorescence emitted by the conjugate. A calibration system allows expressing by interpolation the titer of the sample for each antibody specificity using a specific software developed by bmd. The mixed and antigen-coated microspheres are first incubated with the sample to be analyzed. After the washing step, a phycoerythrin (PE)-labelled secondary anti-human IgA conjugate is added for antibodies quantifications at the surface of each microsphere set. The microspheres are classified on the basis of their unique fluorescence intensity ratio that allows the identity of analyte being tested. Each dot in a white plot corresponds to an individual microsphere.

The description details standard flow cytometry and digital signal processing for data acquisition and analysis, but does not mention AI or ML algorithms for interpretation or decision making.

No.
The device is an in vitro diagnostic (IVD) test designed to detect antibodies associated with Celiac disease for diagnostic purposes, not for treating or preventing a disease.

Yes

Explanation: The "Intended Use / Indications for Use" section explicitly states, "The presence of these antibodies can be used in conjunction with clinical findings to aid in the diagnosis of Celiac disease." Additionally, the final line of this section states, "For in vitro diagnostic use." These statements clearly indicate the device's diagnostic purpose.

No

The device is an in vitro diagnostic (IVD) kit that includes reagents (microspheres, conjugates) and is used on a specific hardware analyzer (FIDIS™ Analyser) which incorporates flow cytometry and digital signal processing. While software is mentioned as part of the system, the core of the device is a physical immunoassay kit and associated hardware.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Explicit Statement: The "Intended Use / Indications for Use" section clearly states: "For in vitro diagnostic use."
  • Intended Use: The device is designed to detect specific antibodies in human serum to aid in the diagnosis of Celiac disease. This is a classic example of an in vitro diagnostic test, as it analyzes a biological sample (serum) outside of the body to provide information for diagnosis.
  • Device Description: The description details a laboratory-based assay using flow cytometry to analyze components of a biological sample (serum incubated with microspheres). This process is characteristic of in vitro diagnostic procedures.
  • Performance Studies: The inclusion of performance studies comparing the device to predicate devices and reporting metrics like sensitivity, specificity, and agreement further supports its classification as an IVD, as these studies are required for regulatory approval of IVDs.

GENERAL DESCRIPTION OF THE DEVICE: H.

FIDISTM Celiac is based on Luminex 100TM Technology.

The Luminex technology (LabMAP™, Laboratory Multi-Analyte Profiling) is a unique system I ho handler tooning of microspheres, flow cytometer, high speed digital signal processor and an X-Y platform for reading 96-well microtiter plates facilitating automated sample acquisition. This combination allows the diagnostic of multiple biological analytes simultaneously.

This multiplexed microsphere-based flow cytometric assay involves fluorescent polystyrene microspheres. The antigen-coated microspheres are mixed and incubated with sample containing the analytes to be detected. A fluorochrome-conjugated detection molecule is subsequently incubated for analyte quantification.

The flow cytometer is equipped with a powerful digital signal processor and two lasers. A red "classification" laser, excites fluorescent molecules intrinsic embedded to the microspheres and a green "reporter" laser, excites the extrinsic fluochrome (Phycoerythrin or Alexa-532nm) bound to the microsphere surface.

During the sample reading, the flow cytometer analyzes individual microsphere, first, by size, and, second, by fluorescence emissions. Digital signal processors and computers algorithms provide simultaneous real-time acquisition of classification and reporter fluorescence signals output from the microspheres. Upon excitation, the emitted fluorescent signal from the microspheres travels through the optics paths to the individual detectors. According to the fluorescence ratio detected by the red laser, each microsphere is classified into on the basis of its unique fluorescence intensity which allows identifying which analyte is being tested. At the same time, the green "reporter" laser beam excites the external second molecule fluorescence to quantify the specific reaction related to each analyte.

Each antigen required for the assay is covalently coupled to an individual set of microspheres through its surface functional groups. The different antigen coupled microspheres are mixed together to constitute the final microspheres reagent. Celiac IgA allows the detection of antigliadin and anti-tissue transglutaminase IgA isotype antibodies. Celiac IgG allows the detection of anti-gliadin IgG isotype antibodies.

The test is performed in a 96 wells blank microplate including a filtering membrane at the bottom of the wells. In the first step, the sample is distributed in duplicate for the 2 isotypes (IgA and IgG) selected in each well containing respectively the Celiac A microspheres mixture, for the IgA isotype and the Celiac G microspheres mixture for the IgG isotype. After incubation, a wash step through a filtration process will eliminate the unbound antibodies. A specific conjugate consisting of either anti-human IgA or IgG antibodies coupled to phycoerythrin, is added to the mixture. It will bind to the previously captured antibodies.

The reaction is then directly measured by the flow cytometer, which categorizes each microspheres set according to its fluorescence colour the microspheres while simultaneously measuring the average fluorescence emitted by the conjugate. A calibration system allows expressing by interpolation the titer of the sample for each antibody specificity using a specific software developed by bmd.

The mixed and antigen-coated microspheres are first incubated with the sample to be analyzed. After the washing step, a phycoerythrin (PE)-labelled secondary anti-human IgA conjugate is added for antibodies quantifications at the surface of each microsphere set.

The microspheres are classified on the basis of their unique fluorescence intensity ratio that allows the identity of analyte being tested. Each dot in a white plot corresponds to an individual microsphere.

TEST PRINCIPLE: J.

FIDIS™ Celiac is based on the use of distinct uniform size code-colored microspheres and a benchtopflow cytometer interfaced to a digital signal processing hardware and software. A red diode laser beam of the flow cytometer classifies each set of microspheres on the basis of its unique fluorescence intensity (red to orange), which allows identifying which analyte is being tested.

At the same time, a green laser beam illuminates the external second molecule fluorescence to quantify the specific reaction related to each analyte.

Each antigen required for the assay is covalently coupled to an individual set of microspheres through its surface functional groups. The different antigen coupled microspheres are mixed together to constitute the final microspheres reagent. Celiac IgA allows the detection of antigliadin and anti-tissue transglutaminase IgA isotype autoantibodies. Celiac IgG allows the detection of anti-gliadin IgG isotype autoantibodies.

The test is performed in a 96 wells blank microplate including a filtering membrane at the bottom of the wells. In the first step, the sample is distributed in duplicate for the 2 isotypes (IgA and

3

IgG) selected in each well containing respectively the Celiac A microspheres mixture, for the IgA is of serent the Celiac G microspheres mixture for the IgG isotype. If the sample tested contains one or more of the suspected antibodies, this (ese) antibody (ies) will bind to the corresponding one of more of the various categories of microspheres. After incubation, a wash step through a filtration process will eliminate the unbound antibodies.

A specific conjugate consisting of either anti-human IgA or IgG antibodies coupled to phycoerythrin, is added to the mixture. It will bind to the previously captured antibodies.

The reaction is then directly measured by the flow cytometer, which categorizes each microspheres set according to its fluorescence color the microspheres while simultaneously measuring the average fluorescence emitted by the conjugate. A calibration system allows expressing by interpolation the titer of the sample for each antigenic specificity.

1.2 Linearity:

Autoantibodies should not be measured in terms of their concentration in serum but as an estimation of the binding capacity between antibody and antigen. This capacity varies between samples and even within the same sample. The main variables characterising these are the nature of the target epitopes and the quantity of antibodies recognising each of these epitopes. For these reasons, the average binding capacity is the best compromise to represent the mean affinity and avidity of the antibody being studied. The result of this measurement is strongly influenced by the reaction conditions.

FIDIS™ Celiac assay has been optimised to express the average binding capacity at the current dilution (1/200) by a flow cytometric reading resulting of the median fluorescence value obtained from 400 microspheres per parameter.

4

Further dilutions potentially give rise to inaccurate results because the reaction conditions and the equilibrium of the immunological reaction will be modified

For this reason linearity is sera dependent in all FIDIS tests and there is no dilution effect.

Traceability (controls, calibrators, or method): 1.3
