Fundamentals of laboratory diagnostics in allergology
The diversity of allergic disorders and their associated underlying mechanisms render allergy diagnosis particularly challenging. There is a palette of available in vivo and in vitro tests, while result interpretation must always be made in conjunction with clinical history. The focus of the present article is on laboratory diagnostics, where several diagnostic tests have been developed targeting different parts of the allergic cascade. The results of these tests may indicate the presence of clinical allergy but also provide information on disease severity, treatment options, and therapy responsiveness. First-line testing involves allergen specific IgE (sIgE) antibody measurements, and several considerations are required when choosing the exact test. Among others, the allergens to be tested, the use of allergen extracts versus molecular components, cross-reactivity aspects, cost, and geographical sensitization patterns need to be considered. There are technical distinctions between main commercially available automated platforms, which is often reflected by differences in their test results. Diagnostically challenging cases can be supplemented by tests assessing the key effector cells, i.e., basophils, mast cells, and eosinophils, as well as by tests targeting several of the released mediators, including tryptase, lipids, and histamine. Overall, non-IgE-based laboratory tests need additional standardization and research to support their clinical utility.
期刊介绍:
Allergo Journal International is the official Journal of the German Society for Applied Allergology (AeDA) and the Austrian Society for Allergology and Immunology (ÖGAI). The journal is a forum for the communication and exchange of ideas concerning the various aspects of allergy (including related fields such as clinical immunology and environmental medicine) and promotes German allergy research in an international context. The aim of Allergo Journal International is to provide state of the art information for all medical and scientific disciplines that deal with allergic, immunological and environmental diseases. Allergo Journal International publishes original articles, reviews, short communications, case reports, and letters to the editor. The articles cover topics such as allergic, immunological and environmental diseases, the latest developments in diagnosis and therapy as well as current research work concerning antigens and allergens and aspects related to occupational and environmental medicine. In addition, it publishes clinical guidelines and position papers approved by expert panels of the German, Austrian and Swiss Allergy Societies.
All submissions are reviewed in single-blind fashion by at least two reviewers.
Originally, the journal started as a German journal called Allergo Journal back in 1992. Throughout the years, English articles amounted to a considerable portion in Allergo Journal. This was one of the reasons to extract the scientific content and publish it in a separate journal. Hence, Allergo Journal International was born and now is the international continuation of the original German journal. Nowadays, all original content is published in Allergo Journal International first. Later, selected manuscripts will be translated and published in German and included in Allergo Journal.
