[Basophil activation test using flow cytometry in Hymenoptera venom allergy]

The basophil activation test (TAB) clearly shows evidence to Hymenoptera venoms. Comparison of the TAB value with the clinical history allows fixation of a threshold that will anticipate the type of clinical reaction by the TAB value. For the technique of TAB 3 dilutions are used. The basophil activation values produce a threshold for each dilution. For the first dilution the threshold is 50% activation: below this threshold, 70% of patients would have a local or systemic reaction and above this threshold, 70% of patients would have a systemic allergic reaction.
