General Information

The presence of IgA endomysial autoantibodies by indirect immunofluorescence is suggestive of active gluten sensitive enteropathies such as celiac disease. Results are primarily useful for diagnosis; they may also be used for monitoring response to treatment with a gluten-free diet, but results are semi-quantitative.
