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 presence of IgM herpes simplex virus (HSV) antibodies indicates acute infection with either HSV type 1 or 2. The IgG antibody assay detects IgG-class antibodies to type-specific HSV glycoprotein G (gG), and may allow for the differentiation of infection caused by HSV types 1 and 2. The presence of IgG-class antibodies to HSV types 1 or 2 indicates previous exposure, and does not necessarily indicate that HSV is the causative agent of an acute illness.
