Suspected substances are tested to your skin all at once and if redness and swelling at the test areas it appears you are allergic and need to proceed to medication in order to contain those reactions. The second type of test is through blood work, this often called RAST, CAP-RAST or specific lgE, in this type of test a doctor or a nurse will be requesting for the total amount of lgE in your blood to identify the allergen that is triggering the symptoms. With all the results gathered the doctor then can proceed to medications and could give you advice on how to avoid yourself from those substances and keep you from experiencing the adverse reactions of the allergy.
