Part Descriptions

LP101174-3   Fraxinus excelsior
Fraxinus is a genus of about 65 species, which are distributed in northern temperate regions. The hardy White ash (Fraxinus Americana), for example, is native and common in eastern North America and also thrives in Europe. The European ash (Fraxinus excelsior) is native to most of Europe, with the exception of northern Scandinavia and the southern Mediterranean. White ash tree (t15) needs to be differentiated from European ash tree (t25).

European ash is a common cause of asthma, allergic rhinitis and allergic conjunctivitis, in particular in Central and Northern Europe. Copyright Copyright © 2006 Phadia AB. Source: ImmunoCap, ImmunoCap

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] Source: Regenstrief LOINC
