RAST Testing

RAST Testing in Hilton Head Island, New River and Beaufort, SC

Blood tests measure the presence of IgE antibodies to specific foods. (IgE, short for “immunoglobulin E,” is the antibody that triggers food allergy symptoms.) In the past, these tests were called “RASTs” (which stands for radioallergosorbent tests) because they used radioactivity, but modern tests do not. Both the blood test and the skin prick tests detect food-specific IgE.

With the skin tests, the result is immediate, but the blood test result will take at least several days to arrive. Unlike the skin prick test, the blood test is not affected by antihistamines and can be performed for people are unable to stop using antihistamines due to current symptoms.
