Intended Use
The Trinity Biotech Captia™ Borrelia burgdorferi IgG/IgM ELISA kit is an Enzyme-Linked Immunosorbent Assay (ELISA) for the qualitative presumptive detection of total (IgG/IgM) antibodies to Borrelia burgdorferi in human serum. This ELISA should only be used for patients with signs and symptoms that are consistent with Lyme disease. Equivocal or positive results must be supplemented by testing with a standardized Western blot procedure. Positive supplemental results are supportive evidence of exposure to B. burgdorferi and can be used to support a clinical diagnosis of Lyme disease.
Device Description
The Borrelia burgdorferi IgG/IgM ELISA kit is an Enzyme-Linked Immunosorbent Assay (ELISA) for the qualitative presumptive detection of total (IgG/IgM) antibodies to Borrelia burgdorferi in human serum. This ELISA should only be used for patients with signs and patients with symptoms that are consistent with Lyme disease. Equivocal or positive results should be supplemented by testing with a standardized Western blot procedure. Positive supplemental results are supportive evidence of exposure to B. burgdorferi and can be used to support a clinical diagnosis of Lyme disease. The Borrelia burgdorferi IgG/IgM ELISA test is an enzyme linked immunosorbent assav to detect IgG/IgM antibodies to Borrelia burgdorferi. Purified Borrelia burgdorferi antigen is attached to a solid phase microtiter well. Diluted test sera is added to each well. If the antibodies are present that recognize the antigen, they will bind to the antigen in the well. After incubation, the wells are washed to remove unbound antibody. An enzyme labeled anti-human IgG/IgM is added to each well. If antibody is present, it will bind to the antibody attached to the antigen on the well. After incubation the wells are washed to remove unbound conjugate. A substrate solution is added to each well. If enzyme is present. the substrate will undergo a color change. After an incubation period the reaction is stopped and the color intensity is measured photometrically, producing and indirect measurement of specific antibody in the patient specimen.

No
The device description and performance studies detail a standard ELISA assay, which is a biochemical test, not a software-based or image processing technology that would typically incorporate AI/ML. There is no mention of AI, ML, or related terms in the document.

No
This device is an in vitro diagnostic (IVD) test used to detect antibodies for diagnostic purposes, not to treat or provide therapy for a disease.

Yes.
The device is used for the qualitative presumptive detection of antibodies to Borrelia burgdorferi in human serum to support a clinical diagnosis of Lyme disease, which directly indicates its diagnostic purpose.

No

The device is an ELISA kit, which is a laboratory assay involving physical reagents and a photometric measurement, not solely software.

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

Here's why:

  • Intended Use: The intended use explicitly states it's for the "qualitative presumptive detection of total (IgG/IgM) antibodies to Borrelia burgdorferi in human serum." This involves testing a biological sample (human serum) in vitro (outside the body) to gain information about a patient's health status (exposure to Borrelia burgdorferi).
  • Device Description: The description details a laboratory test procedure (ELISA) performed on human serum to detect antibodies. This is a classic example of an in vitro diagnostic test.
  • Performance Studies: The document describes performance studies conducted on human serum samples (CDC Lyme Disease Serum Panel, fresh sera from patients). This further confirms its use in a diagnostic context.

The core function of the device is to analyze a biological sample in vitro to provide information for a clinical diagnosis, which is the definition of an In Vitro Diagnostic device.

The results are presented as a means to convey further information on the performance of this assay with a masked, characterized serum panel. This does not imply an endorsement of the assay by the CDC.
Table 1 Trinity Biotech B. burgdorferi IgG/IgM ELISA Results
Because the equivocals would have been tested by immunoblotting in a 2-step test system, they were considered 1-step positive for purposes of calculating % agreement. The Trinity Bitoech Borrelia burgdorferi IgG/IgM ELISA demonstrated 71% (30/42) agreement with clinical diagnosis of Lyme disease.

Study 2

One hundred seventy-six fresh sera from patients of various ages and genders that were submitted to a large clinical lab for B. burgdorferi antibody testing were tested on the Trinity Biotech B. burgdorferi IgG/IgM ELISA and BioWhittaker Lyme Stat. Any serum found positive or equivocal was tested by Mardx Diagnostics Western Blot on both IgG and IgM. The results are illustrated in Table 2.

Precision

Seven sera were assayed ten times each on three different plates at three different sites. An additional three sera were assayed ten times each on three different plates at two different sites. The intersite precision is shown in Table 3. With appropriate technique the user should obtain precision of 1yr | 8 | 0 | 0 | 8 | 100.0%
