Please note:

EMA Binding Assay (Eosin-5-maleimide) is for investigation of hereditary spherocytosis and selected red cell membrane disorders. This is different to Endomysial antibody (EMA) serology which is a serological test used in the investigation of coeliac disease.

Where the clinical information indicated investigation for coeliac disease and an EMA binding assay has been requested, the request cannot be processed as ordered and will be declined. A new request for the appropriate coeliac serology (endomysial antibody and/or tissue transglutaminase IgA, as appropriate) will be required.
