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:
“We do not quite say that the new is more valuable because it fits in; but its fitting in is a test of its value—a test, it is true, which can only be slowly and cautiously applied, for we are none of us infallible judges of conformity.”
—T.S. (Thomas Stearns)
