radioallergosorbent test

 (RAST) [ra″de-o-al″er-go-sor´bent]
a radioimmunoassay for the measurement of extremely small amounts of specific IgE antibody to a variety of allergens in the serum of a patient, using an allergen complex fixed in a solid-phase matrix, passing the serum over the matrix so the allergen can catch and bind specific IgE antibodies, and detecting the antibody using radiolabeled anti–human IgE antibody. Uptake of the labeled antibody is proportional to the level of specific serum IgE antibodies to the allergen. RAST is used as an alternative to skin tests to determine sensitivity to suspected allergens.
