The Basophil Activation Test (BAT) is a blood test that measures the activation of basophils, a type of white blood cell, in response to specific allergens. This test is particularly useful in diagnosing food allergies.

Process: In BAT, basophils are isolated from a blood sample and exposed to potential allergens. If the patient is allergic to a specific substance, the basophils will activate, which is detected using flow cytometry.

Advantages: This test is highly sensitive and can help in cases where traditional skin or blood tests are inconclusive. It also poses minimal risk to the patient, as it is performed in vitro (outside the body).
