Part Descriptions
LP13932-6 Oryza sativa
Test to detect allergy to rice, the allergen code is f9. All rice grown in the United States and most of that grown in other countries belongs to the species Oryza sativa in the family Poaceae. Rice is a staple food for almost half the world's population. Rice may be cultivated in flooded fields(paddy-grown) or hill-grown(lower quality) on tropical or subtropical terrain. White rice has the husk, bran and germ removed. Brown rice has only the inedible husk removed. Proteins with molecular masses of 14-16, 26, 33, and 56 kDa are potentially allergeneic in patients with rice allergy. Extensive cross-reactivity occurs among pollen of the different species within the Poaceae occurs frequently. Rice allergy may induce symptoms of food allergy, asthma, rhinitis, eczema, and urticaria in areas where rice is a staple food, like the Far East.

LP32397-9 Ab.IgG4
IgG4 is the least common subtype of IgG, and it has a variety of functions. In the context of allergic disease it is thought to have an immune-inhibitory role in preventing anaphylaxis and is commonly known as a "blocking" antibody. IgG4 binding to an allergen can compete with IgE-mediated binding, thereby inhibiting the activation of mast cells and basophils and IgE-mediated presentation to T-cells. Measuring IgG4 and its ratio to IgE has a role in monitoring allergen specific immunotherapy PMID: 26023323. IgG4 is also thought to have a role in autoimmunity and be involved in a less defined entity known as IgG4-Related Disease, a chronic immune-mediated fibroinflammatory disorder that often manifests with tumor-like masses .[https://www.merckmanuals.com/professional/musculoskeletal-and-connective-tissue-disorders/igg4-related-disease/igg4-related-disease]
