RAST stands for RadioAllergoSorbent Test; RAST is done on a sample of blood. RAST (radioallergosorbent test) is used to check allergy sensitivity to specific substance. These tests measure the level of allergic antibodies in the body or a specific type of antibodies known as IgE, IgE that are only present when an allergic reaction occurs. These blood tests may not be as effective as skin testing and tend to be more expensive, but can be useful sometimes.
