Rapid house dust mite (Acari: Pyroglyphidae) and storage mite (Acari: Glycyphagidae and Acaridae) allergen test.

Ten years ago a simple technique was described for detecting guanine from house dust mite excretions. The level of guaninine correlated well with the level of house dust mite allergens. Detection of storage mites is becoming more and more important, and these mites also produce guanine. Therefore, the above-mentioned technique provides a good indication of levels of storage mite allergens.
