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.
To determine if IgM antibody is true antibody, the serum is absorbed with anti-human IgG antibody (Gullsorb test) to remove IgG prior to testing for IgM. A concurrent test with PBS in place of Gullsorb is the control. Table 2 shows examples of tests with MIF IgM-positive patient sera.
