BÜHLMANN BAT (Basophil Activation Test) in Allergy Diagnosis (Exploratory Pilot Study)
Exploratory Pilot Study of BÜHLMANN Automated Basophil Activation Test as an Aid to Diagnosis of Immediate Type Allergic Disorders
The goal of this exploratory pilot study is to generate early data needed for future validation studies of the automated BÜHLMANN BAT (Basophil activation test) assay. The main questions it aims to answer are:
Does the BAT assay use the optimal allergen concentrations for stimulation, and how do its preliminary cut-offs perform in a real-world clinical scenario?
Participants older than 1.5 years who are being evaluated for possible allergy sensitization will provide one additional blood tube during their routine blood draw as part of the regular medical care. The study involves only one visit and does not provide direct personal benefit.

Allergy / hypersensitivity to the 6 allergens
10 patients, each with an allergy / hypersensitivity to the following allergens: (i) Peanut, (ii) Hazelnut, (iii) Honey Bee, (iv) Yellow Jacket Venom, (v) House Dust Mite (HDM) (vi) Cat Epithelium.
No additional non-allergic control subjects will be recruited specifically for this study.
Participants with a clinically confirmed hypersensitivity to one of the six investigated allergens will serve as allergen-specific controls for the remaining allergens for which they have no known hypersensitivity.
