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.
The IgG class of antibodies is composed of four different subtypes of IgG molecules called the IgG subclasses. These are designated IgG1, IgG2, IgG3 and IgG4. Patients with persistently low levels of one or two IgG subclasses and a normal total IgG level have a selective IgG subclass deficiency.
