The Vibrant Clinical Team does not recommend a “gluten challenge” to an individual who is already aware they have adverse symptoms driven by gluten. However, with any antibody testing, if the antigen (in this case gluten or other peptides in wheat) has been removed for a significant amount of time (variable amongst individuals), the body will no longer mount an IgA/IgG antibody response and will render an antibody test as a “false negative”. Such is the case with our Wheat ZoomerTM test.
However, the Wheat ZoomerTM looks at more than gluten and wheat antigens, and if a patient is still experiencing symptoms, it would be helpful to look at the intestinal permeability (“leaky gut”) panel from the Wheat ZoomerTM. Also, many of our practitioners find that running a Wheat ZoomerTM can demonstrate a person’s true compliance in following a gluten or wheat free diet. As we know, it’s extremely difficult to eliminate gluten 100%, and often patients will be obtaining gluten from a hidden source unknown to them and will produce an antibody response. Research suggests that a single exposure from gluten can elevate antibodies anywhere from 2-6 months in a person (and this varies individually). Therefore, while the Wheat ZoomerTM does hold a little more clinical utility and direction if a person is actively consuming gluten, there is still useful insight in an already gluten-free patient
