Test Overview
Multiplex Flow Immunoassay
Marker of celiac disease associated with gluten-sensitive enteropathy or dermatitis herpetiformis. A positive result indicates the presence of human-tTG IgG antibodies and suggests the possibility of certain gluten sensitive enteropathies such as celiac disease and dermatitis herpetiformis.
Negative (0-14 U/mL)
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
The presence of immune complexes or other immunoglobulin aggregates in the patient sample may cause an increased level of non-specific binding and produce false positives in this assay. IgG antibody is more sensitive but less specific than IgA antibody. Since IgA deficiency is relatively common among celiac patients, the combined use of IgA and IgG antibodies is recommended for diagnosis. Hemolytic samples may cause results to be inaccurate due to hemolysis interferent.
