These are diagnostic tools designed for the detection of gluten, a protein found in wheat, barley, and rye, within food products. The devices typically function through an immunoassay, where specific antibodies bind to gluten proteins, producing a visible reaction that indicates the presence or absence of gluten above a certain threshold. As an example, an individual adhering to a gluten-free diet might use such a tool to verify that a commercially prepared sauce does not contain gluten before consumption.
The importance of these diagnostic aids lies primarily in their ability to support individuals managing celiac disease or non-celiac gluten sensitivity in maintaining their dietary restrictions. The benefit extends to offering a level of reassurance when dining out or consuming pre-packaged foods where ingredient lists may be incomplete or misleading. Historically, individuals relied solely on manufacturer labeling and personal judgment; these tools provide an objective, albeit limited, assessment.
