New blood test could make allergy diagnosis faster and easier
NCT ID NCT07596303
First seen Jun 27, 2026 · Last updated Jul 17, 2026 · Updated 1 time
Summary
This study is testing a new blood test (called BÜHLMANN BAT) to see if it can help diagnose allergies to peanuts, insect venom, dust mites, hazelnut, and cat dander. About 60 people aged 1.5 years and older who are already being checked for allergies will give one extra tube of blood during their regular visit. The test is not yet proven, and participants will not get direct personal benefits from joining.
