Allergic diseases such allergic such as allergic rhinitis, allergic conjunctivitis and asthma are chronic diseases caused by immune system reacting inappropriately to normally harmless substances such as house dust mites, animal dander, etc…

The most common types of allergic reactions are medicated by IgE antibodies. Most allergy blood tests are designed to measure allergen specific IgE; however, older generation blood tests have their limitations. While requiring a large amount of blood for testing, a total IgE of more than 2000 IU/ml would result in very frequent false positive reactions. This is often the reason why some patients test positive to “everything”, which is especially common in patients with atopic dermatitis. The latest generation of multiplex assay employs nanotechnology. The size of these nanobeads is 1000-fold smaller than the chip microarray, allowing more than 200 allergens, half of which are molecular allergens, to be tested with less than 200uL of serum. With the reaction surface drastically reduced, it can accurately test serum with a total IgE of up to 45,000 IU/ml.
