Part Descriptions

LP14055-5 Holcus lanatus
Velvet grass is native and common to most of Europe, though it is absent in the northernmost regions. It now has a worldwide distribution including temperate regions in western Eurasia, the USSR, and Australia. It was introduced in North America, where it is occasionally cultivated as meadow. The name Velvet grass perhaps comes from the appearance its pale purple flower heads make when growing amassed in an open field. In many countries H. lanatus is considered a weed and only of minor importance for grazing.

Velvet grass pollen can induce asthma, allergic rhinitis and allergic conjunctivitis. 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
