Blood Allergy Testing
Learn more about Blood Allergy Testing
Blood allergy testing is used to identify allergens, which may cause brain inflammation and brain disorders.
Millions of Americans are allergic to something: whether its seasonal allergies, pets, food or possibly dust in the house. Blood allergy testing can assist in discovering what triggers your allergy symptoms and us choose the best treatment for you.
Blood tests measure the presence of IgE antibodies to specific foods. (IgE, short for immunoglobulin E, is the antibody that triggers food allergy symptoms.) In the past, these tests were called RASTs (which stands for radioallergosorbent tests) because they used radioactivity, but modern tests do not.
Blood Tests vs. Skin Tests
Both the blood test and the skin prick tests detect food-specific IgE. Unlike the skin prick test, the blood test is not affected by antihistamines and can be performed for people with extensive rashes that prevent using skin tests.
