New in vitro diagnostic reagents and analyzer for various allergens Launch announcement for Allerport® HRT and its dedicated analyzer, the Allerport HRT System
May 10, 2011
Tokyo, Japan, May 10 2011 --- Kyowa Medex Co., Ltd. ("Kyowa Medex") announced today the release of two products on May 16 2011. The first, developed by Shionogi & Co., Ltd. (Head office: Osaka) is Allerport® HRT, in vitro diagnostic reagent for measuring the histamine released due to allergens (histamine release test, or HRT); the test kit assists in the diagnosis of the antigens that cause type I allergies. The second product, an analyzer developed by Kyowa Medex specifically for Allerport® HRT, is an enzyme immunoassay system called the Allerport HRT System.
Allerport® HRT is a histamine release test kit that uses a cell response assay to measure the amount of histamine released from blood cells (basophils) triggered by allergens.
The Allerport HRT System is a fully automated device for measuring histamine release. Previously, the cell separation, histamine release reaction, immune competitive reaction, and color absorbance measurement process have been performed manually, but Allerport HRT System can now fully automate the entire assay process.
A histamine release test (HRT) helps to diagnose the allergens that cause diseases characterized by allergic reactions such as food allergies, allergic rhinitis, atopic asthma, some atopic dermatitis, and hives. This test is highly specific and therefore will contribute to accurate diagnosis.
The test results from Allerport® HRT are measured using the dedicated the enzyme immunoassay device, Allerport HRT System, which simplifies daily test procedures and enables quick measurements of the necessary allergens among 32 choices.
Kyowa Medex has been focusing on developing, manufacturing and marketing of in vitro diagnostic reagents and analyzers, and we endeavor to help to improve people's quality of life by responding to their medical needs.
