Alexandra Sifferlin has recently reported about a new blood test that can diagnose the severity of a person’s allergy without being invasive. The test is called basophil activation test (BAT).

A blood test can reveal just how severe a person’s food allergy is and could possibly replace more invasive testing, a new study published Wednesday morning suggests.
Around 4 to 6% of American children have food allergies, a risk the U.S. Centers for Disease Control and Prevention (CDC) calls “a growing food safety and public health concern.” However, determining whether someone has a food allergy and then determining just how severe that food allergy is can be tricky.
To assess whether someone has a specific allergy, doctors will perform skin pricks or blood tests to look for skin reactions or high levels of allergy-specific antibodies. But doctors still don’t have a simple tool to test just how allergic a person is to a specific food. In some cases, the individual will need to eat whatever food they are allergic to in the presence of a physician so the doctor can determine the severity of their allergy in a safe space.
