Part Descriptions

LP16996-8 Humulus lupus
Native to Europe and western Asia, the Hop plant is now cultivated in North and South America, Africa, Asia and Australia. The plant is a perennial climber growing to 6m at a medium rate. "Hops" is the common term for either the dried flower heads as a whole or the extract, with a bitter taste and aromatic odour, from the dried pine cone-like fruit of the plant. Hops contribute flavour and aroma and act as a preservative in brewed alcoholic beverages, and are used medicinally. The extract may be in solid, liquid or oil form.

Hops may uncommonly induce symptoms of food allergy or skin allergy in non-occupationally sensitised individuals. Occupational allergy may also commonly be associated with exposure to Hops. 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
