Intended Use
Celikey IgG is intended for the semiquantitative and qualitative measurement of anti-tissue transglutaminase (tTG) IgG antibodies in human serum and plasma. Celikey IgG is based on recombinant human tissue transglutaminase as antigen and is useful as an aid in the clinical diagnosis of patients with celiac disease.
Device Description
Celikey IgG is an indirect noncompetitive enzyme immunoassay for the semiquantitative and qualitative determination of tTG (IgG) antibodies in human serum or plasma. Antibodies specific for tTG present in the patient sample bind to the antigen. The test kit contains microplate strips coated with purified recombinant human tTG antigen, calibrators, positive and negative controls, enzyme-labeled conjugate, substrate and substrate stop solution, sample diluent and wash buffer.
More Information

No
The description details a standard enzyme immunoassay (ELISA) kit for antibody detection, which does not inherently involve AI or ML. The "Mentions AI, DNN, or ML" section is explicitly marked as "Not Found".

No
The device is used for diagnostic purposes, specifically for measuring antibodies to aid in the clinical diagnosis of celiac disease, rather than providing therapy.

Yes
The product information explicitly states, "Celikey IgG...is useful as an aid in the clinical diagnosis of patients with celiac disease." This indicates its role in identifying or confirming the presence of a disease, which is the definition of a diagnostic device.

No

The device description clearly states that the device is an enzyme immunoassay test kit containing physical components such as microplate strips, calibrators, controls, and reagents. This indicates it is a hardware-based diagnostic test, not a software-only device.

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

Here's why:

  • Intended Use: The intended use explicitly states it's for the "measurement of anti-tissue transglutaminase (tTG) IgG antibodies in human serum and plasma." This involves testing a sample taken from the human body in vitro (outside the body).
  • Aid in Clinical Diagnosis: The intended use also states it's "useful as an aid in the clinical diagnosis of patients with celiac disease." This is a key characteristic of IVD devices, which are used to provide information for diagnostic purposes.
  • Device Description: The description details a laboratory test kit that uses an "indirect noncompetitive enzyme immunoassay" to detect antibodies in "human serum or plasma." This is a typical format for an IVD test.
  • Components: The list of components (microplate strips, calibrators, controls, reagents) are all standard elements of an IVD test kit.

The information provided clearly indicates that this device is designed to be used in vitro to analyze human samples for diagnostic purposes, which aligns with the definition of an In Vitro Diagnostic device.

Device Description

Celikey IgG is an indirect noncompetitive enzyme immunoassay for the semiquantitative and qualitative determination of tTG (IgG) antibodies in human serum or plasma. The wells of a microplate are coated with recombinant human tTG antigen. Antibodies specific for tTG present in the patient sample bind to the antigen.

In a second step the enzyme labeled second antibody (conjugate) binds to the antigen-antibody complex which leads to the formation of an enzyme labeled conjugate-antibody-antigen complex. The enzyme labeled antigen-antibody complex converts the added substrate to form a colored solution.

The rate of color formation from the chromogen is a function of the amount of conjugate complexed with the bound antibody and thus is proportional to the initial concentration of the respective antibodies in the patient sample.

The test kit contains microplate strips coated with purified recombinant human tTG antigen, calibrators, positive and negative controls, enzyme-labeled conjugate, substrate and substrate stop solution, sample diluent and wash buffer.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

The comparability of INOVA QUANTA Lite™ h-tTG IgG and Celikey® IgG tTG IgG Antibody assay is supported by a data set including

  • results obtained within a comparison study analyzing positive, equivocal and negative sera.
  • results obtained for clinically defined sera. .
  • results obtained for samples from apparently healthy subjects (normal population).

The data show that the assay performs as expected from the medical literature. In summary, all available data support that the new device is substantially equivalent to the predicate device and that the new device performs according to state-of-the-art expectations.

Intended Use Statement

Celikey IgG is intended for the semiquantitative and qualitative measurement of anti-tissue transglutaminase (tTG) IgG antibodies in human serum and plasma. Celikey IgG is based on recombinant human tissue transglutaminase as antigen and is useful as an aid in the clinical diagnosis of patients with celiac disease.

General Description of the Device

Celikey IgG is an indirect noncompetitive enzyme immunoassay for the semiquantitative and qualitative determination of tTG (IgG) antibodies in human serum or plasma. Antibodies specific for tTG present in the patient sample bind to the antigen.

The test kit contains microplate strips coated with purified recombinant human tTG antigen, calibrators, positive and negative controls, enzyme-labeled conjugate, substrate and substrate stop solution, sample diluent and wash buffer.

Celikey® IgG tTG IgG Antibody Assay Test Principle

Celikey IgG is an indirect noncompetitive enzyme immunoassay for the semiquantitative and qualitative determination of tTG (IgG) antibodies in human serum or plasma. The wells of a microplate are coated with recombinant human tTG antigen. Antibodies specific for tTG present in the patient sample bind to the antigen.

In a second step the enzyme labeled second antibody (conjugate) binds to the antigen-antibody complex which leads to the formation of an enzyme labeled conjugate-antibody-antigen complex. The enzyme labeled antigen-antibody complex converts the added substrate to form a colored solution.

The rate of color formation from the chromogen is a function of the amount of conjugate complexed with the bound antibody and thus is proportional to the initial concentration of the respective antibodies in the patient sample.

Device Comparison

Both assays (the predicate and the new device) are indirect noncompetitive enzyme immunoassays for the semi-quantitative and qualitative determination of IgG antibodies to tissue transglutaminase (endomysium) in human serum. Both assays recommend the same sample dilutions and use comparable antigens and detection systems.

In accordance to the relevant scientific literature both assays state in the Intended Use, that the measuring of the IgG antibodies against tissue transglutaminase provides aid in the diagnosis of patients with celiac disease.

A difference between both assays is that the predicate device is only recommended for use in serum specimen while the new device is, intended for use with serum and plasma.

The cut-off in the predicate device assay is evaluated by using a low and a high positive Standard and a grading of the results in negative, weak, moderate and strong positive. The new device uses a set of six Calibrators and classifies the results as negative, equivocal and positive.

Laboratory equivalence

The comparability of INOVA QUANTA Lite™ h-tTG IgG and Celikey® IgG tTG IgG Antibody assay is supported by a data set including

  • · results obtained within a comparison study analyzing positive, equivocal and negative sera.
  • results obtained for clinically defined sera. .
  • · results obtained for samples from apparently healthy subjects (normal population).

The data show that the assay performs as expected from the medical literature.

In summary, all available data support that the new device is substantially equivalent to the predicate device and that the new device performs according to state-of-the-art expectations.
