There is no laboratory test for<unk> . Typically testing is done by an "elimination challenge," to see if symptoms improve, or "provocative challenge," which intends to induce a controlled reaction as a means of confirming diagnosis. During provocative challenge, the person is given incrementally higher doses of<unk> s, usually aspirin, under medical supervision, until either symptoms appear or the likelihood of symptoms appearing is ruled out. This only pertains to short-term symptoms such as digestive, respiratory, and skin itching, rather than slower-developing symptoms such as nasal polyps.
