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.
Nothing bad: Iga is the amount of immunoglobulin a and it can be measured in the blood serum and less commonly in the saliva. While a low amount of serum IgA may predispose some people to recurrent infections, an elevated serum IgA is nothing to worry about. It means the person is making good amounts of antibody.
