Allergen‐induced basophil activation: CD63 cell expression detected by flow cytometry in patients allergic to <i>Dermatophagoides pteronyssinus</i> and <i>Lolium perenne</i>

Abstract

The basophil activation test is a highly reliable technique in the diagnosis of allergy to inhalant allergens. The sensitivity of the basophil activation test was 93.3%, and its specificity 98.4%, when using a cut-off point of 15% activated basophils as positive result.
