RIDA®CHIP FoodGuide – miniaturized, fast, cost efficient

IgG food allergies, often called food intolerances, are believed to affect between 20 % and 40 % of the overall population.

Due to perturbations in the human gut, food antigens can get in contact with the immune system. This leads to the production of food specific IgG antibodies, circulating in the blood stream. Repetitive exposure to these food allergens can lead to the formation of immune complexes, which in turn can lead to local inflammations and cause complaints.

The symptoms caused by these local inflammations vary and  occur only up to 12 h – 48 h after allergen exposure. Thus, it is nearly impossible to relate a symptom to a previously eaten food.

Symptoms that are often observed together with food specific IgG antibodies:

RIDA®CHIP FoodGuide offers a reliable state-of-the-art microarray technology to detect food specific IgG antibodies for up to 100 allergens.

RIDA®CHIP FoodGuide comes in a standard ELISA format. This enables you to use your conventional equipment and also conventional ELISA automats such as the DS2 or the DSX (Dynex).

Food antigens are coupled to the surface of the microarray slide. Primary food specific IgG antibodies bind to these food antigens and can be detected by the conjugate antibody. Catalized by an enzymatic process, the substrate precipitates on the slide and can be detected by our state-of-the-art micro array reader.

RIDA®CHIP FoodGuide comes as a automatable solution. It is completed by the micro array reader and software to create reports.

Importantly, the Software also runs on the reader, such that all information are always automatically updated with the software database.

The Software does not only guide you trough the whole process, it will also generate a comprehensive report that enables the patients to understand their lab results within one glimpse.
