The basophil activation test BAT is a functional assay that measures the degree of degranulation following stimulation with allergen or controls by flow cytometry. A method for determining degranulation of basophilic granulocytes in a whole blood sample comprising contacting said sample with an antibody that binds to CD63 molecules and. The basophil activation test BAT using flow cytometry has supplanted traditional methods of measuring basophil degranulation using histamine and other mediator release.

The development of basophil degranulation is assessed by flow cytometry methods that can quantify the presence of cell surface-bound allergen-specific IgE. Basophil Degranulation Test is a descriptor in the National Library of Medicines controlled vocabulary thesaurus MeSH Medical Subject Headings. The development of basophil degranulation is assessed by flow cytometry methods that can quantify the presence of cell surface-bound allergen-specific IgE antibodies as well as the degranulation induced after incubation with the allergenic product via a marker of.
