|Test Code||EMAA / 3083000MC|
|Test||ENDOMYSIAL ANTIBODIES, IgA|
|Methodology||Indirect Immunofluorescence Assay|
|Description||Useful for the diagnosis of dermatitis herpetiformis and celiac disease and for monitoring adherence to gluten-free diet in patients with dermatitis herpetiformis and celiac disease. Because of the high specificity of endomysial antibodies for celiac disease, the test may obviate the need for multiple small bowel biopsies to verify the diagnosis. This may be particularly advantageous in the pediatric population, including the evaluation of children with failure to thrive.|
|Specimen||Draw blood in either a plain, red-top tube or serum gel tube. Spin down and send 1.0 mL (minimum: 0.5 mL) of serum refrigerated in a screw-capped, plastic vial.|
|Reference Values||Report includes presence and titer of circulating IgA endomysial antibodies.
Negative in normal individuals; also negative in dermatitis herpetiformis or celiac disease patients adhering to gluten-free diet.
|Analytic Time||2 Days|
|Day(s) Test Set Up||Monday through Friday|
