title: [Application of basophil activation test in diagnosing aspirin hypersensitivity].
abstract: In the face of increasing prevalence of hypersensitivity reactions, introduction of effective, reliable and safe methods plays a crucial role in their diagnosing. Among the currently available laboratory (in vitro) methods is basophil activation test (BAT). It is a flow- cytometry based assay that allows to identificate in the blood sample basophils and additionally to asses the degree of cell activation after exposure to an antigen. The most common superficial identification markers are CD63 and CD203c, which increase in number after activation. Basophil actvation test can be applied to confirm diagnosis of allergy to Hymenoptera venoms, food, pollens and hypersensitivity to drugs. The aim of present paper is to present theoretical methods of this test as well as its pros and cons. We focus also on presentation of clinical case where BAT seemed to be a necessary addition to a routine diagnostic pathway. We present a case of identification of the culprit drug which caused an anaphylactic reaction.
