An equation says that two things are equal. It will have an equals sign = like this: 7 + 2 = 10 â 1. That equation says: what is on the left (7 + 2) is equal to what is on the right (10 â 1) So an equation is like a statement this equals that. Here is another equation:
Detection of antibodies to gliadin, one of the major protein components of gluten, is a sensitive assay useful in diagnosing celiac disease. However, gliadin antibodies may be found in individuals without celiac disease; thus gliadin antibody assays are less specific than assays measuring antibodies to endomysium and transglutaminase.
Presence of the tissue transglutaminase (tTG) IgA antibody is associated with glutensensitive enteropathies such as celiac disease and dermatitis herpetiformis. tTG IgA antibody concentrations greater than 40 U/mL usually correlate with results of duodenal biopsies consistent with a diagnosis of celiac disease.
