RAST is an in vitro test for hypersensitivity to specific allergens that is used when patients are likely to have anaphylactic reactions to other forms of skin testing. Cutaneous scratch testing or intracutaneous testing is more likely to cause anaphylaxis. Serum IgE level is elevated in atopic reactions but is not diagnostic for specific allergens.
