Each participant will be asked to provide appropriate (general medical history, asthma history, current medications, past asthma medications, demographic information, weight height, smoking history, allergies, and prior surgeries. Participants will be asked to complete an Asthma Control Questionnaire, which will be scored to determine how well their asthma is controlled. All consented registrants will be given the opportunity to visit The Ohio State University Asthma Clinical Research Center where an extensive lung function test (spirometry) will be provided. At the Asthma Clinical Research Center each registrant will perform at least three lung function efforts, then given two puffs of albuterol (a fast acting medication that opens airways). After a standard waiting period that meets the standards of the American Thoracic Society, a second set of lung function test will be done. The results of the second set of tests will reflect any reversibility in lung function levels, and will serve as an indicator that treatment may improve lung function. All participants will be given copies of all lung function tests, and the results of the test will be explained to them. All study procedures are provided without cost to the registrant.
