Strategies to Improve Diagnosis and Treatment of Asthma in Canadians
Our study will enroll 644 randomly-selected Canadians who have been diagnosed with asthma by a physician within the previous five years.
It will be determined what diagnostic tests were initially performed to make this diagnosis.
Participants will undergo lung function testing over 6-8 weeks to determine their respiratory status and to confirm they have asthma.
Participants may be followed up to one year depending on their test results.
