LEGIONELLA PNEUMOPHILA IGG/IGM
The Trinity Biotech Captia™ Legionella pneumophila IgG/IgM ELISA kit is an Enzyme-Linked Immunosorbent Assay (ELISA) for the qualitative detection of total antibodies (IgG and IgM) to serogroups 1-6 in serum from patients with clinical suspicion of Legionella Disease. The assay is not intended to differentiate between the serotypes of Legionella pneumophila.
The Legionella pneumophila IgG/IgM ELISA kit is an Enzyme-Linked Immunosorbent Assay (ELISA) for the qualitative detection of total antibodies (IgG and IgM) to Legionella pneumophila serogroups 1-6 in serum from patients with clinical suspicion of Legionella Disease.
The Legionella pneumophila IgG/IgM ELISA test is an enzyme linked immunosorbent assay to detect IgG/IgM antibodies to legionella. Purified Legionella pneumophila antigen (serogroups 1, 2, 3, 4, 5, 6) 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 an indirect measurement of specific antibody in the patient specimen.
Here's a breakdown of the acceptance criteria and study details for the Trinity Biotech Legionella pneumophila IgG/IgM ELISA Test Kit, based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
The document doesn't explicitly state pre-defined acceptance criteria in terms of numerical thresholds for sensitivity, specificity, or agreement. Instead, it presents the results of a comparative study against a predicate device (Legionella IFA) and implicitly suggests that these results demonstrate substantial equivalence. The precision study evaluates consistency rather than diagnostic accuracy.
Performance Metric | Acceptance Criteria (Implicit) | Reported Device Performance (Site 1) | Reported Device Performance (Site 2) |
---|---|---|---|
% Agreement Positive (compared to IFA positive) | Demonstrate substantial agreement with predicate device (IFA) | 90.00% (95% CI: 79.0% - 100%) | 98.53% (95% CI: 95.6% - 100%) |
% Agreement Negative (compared to IFA negative) | Demonstrate substantial agreement with predicate device (IFA) | NA (no IFA negative samples) | 98.57% (95% CI: 95.7% - 100%) |
Precision (Intra-assay CV) | Not explicitly stated, but common industry practice aims for low CVs (e.g., |
