| challenge test |
A test done to determine whether or not a person's bronchi are hyperresponsive. The subject breathes in air containing carefully controlled amounts of a substance known to cause bronchoconstriction. (Common substances used include methacholine, histamine, and vaporized salt water.) The bronchi of people with asthma respond to much smaller amounts of the substance than the bronchi of people who do not have asthma. This test is often used to confirm a diagnosis of asthma if there is uncertainty.
