Explanation:
Detailed explanation-1: -The RAST (Radioallergosorbent test) is a laboratory test performed on blood. It tests for the amount of specific IgE antibodies in the blood which are present if there is a true allergic reaction. One of the most common methods of allergy testing is the scratch test or skin prick test.
Detailed explanation-2: -An allergen-specific immunoglobulin E (IgE) test is a blood test that measures the levels of different IgE antibodies in a person’s blood. Allergen-specific IgE tests are sometimes used to diagnose and better manage food allergies. They can also be helpful for environmental allergy diagnosis in some cases.
