Silk Allergy IgE Blood Test

What is the purpose of this test?

Order this Silk Allergy IgE Blood Test measures the IgE antibody levels in the blood to detect an allergy to silk. The silk that is cultured from the Bombyx mori is highly sought after for its exclusive use in textiles. However, workers in the silk industry are subjected to significant levels of exposure. While handling pure silk, they are exposed to silk waste containing highly potent allergens, such as insect material. 

As a result, allergic respiratory symptoms are commonly observed among silk industry workers, which have been attributed to proteins from the silkworm. While the substance sericin, which glues together the thread filaments, was previously thought to be the culprit, this hypothesis has yet to be confirmed. It should be noted that dust containing pure silk is not considered a potent allergen.
