A RAST test (short for radioallergosorbent test) is a blood test used to determine to what substances a person is allergic. This is different from a skin allergy test, which determines allergy by the reaction of a person's skin to different substances.
Because there are other tests that help with confirmation, results are best interpreted by a doctor. Since at least 2010, health organizations have recommended that the RAST test be abandoned as a diagnostic test for allergy in favor of more sensitive fluorescence enzyme-labeled assays.

Famous quotes containing the word test:
“Our decision about energy will test the character of the American people and the ability of the President and the Congress to govern this nation. This difficult effort will be the “moral equivalent of war,” except that we will be uniting our efforts to build and not to destroy.”
—Jimmy Carter (James Earl Carter, Jr.)
