Clinical and Procedure

Clinical Utility

The BasoFunction test may be useful with patients who have a suggestive history of adverse reactions to the indicated allergen and for whom skin testing is not appropriate or available.

Procedure

Cell Setup: Peripheral blood leukocytes are enriched from heparinized whole blood and stimulated with fMLP Basophil Activation Test, allergen (BasoFunction Test) or buffer alone. Following a brief culture the supernatant containing secreted histamine is separated from the cells. Histamine Test: A validated histamine ELISA quantifies histamine that was secreted by any stimulated control. Viracor Eurofins determined the performance characteristics of this test. This test has not been cleared or approved for diagnostic use by the U.S. Food and Drug Administration.
