Stand-alone food allergy diagnostic test based on basophil activation

Stanford researchers have developed a rapid, accurate, and accessible method to test for food allergy and other types of allergy. This standalone diagnostic test can accurately predict the severity of an allergic reaction to allergens using a novel blood-based biomarker based on the activation of basophils.

The test analyzes blood after its collection and can deliver results in less than 3 hours at the point-of-care. Current allergy tests can take up to two weeks and faster methods such as the skin prick tests (SPT) can trigger allergic reactions. In contrast, this new test is fast, safe and convenient.

Patients who experience adverse reaction can obtain results quickly to avoid repeated exposure to the offending allergen. This rapid diagnostic test can also be used for monitoring treatment progress for patients undergoing allergy immunotherapy.
