What does ASTD stand for? Definition of ASTD in the Abbreviations.com acronyms and abbreviations directory.
The most certain way to diagnose asthma is with a lung function test, a medical history, and a physical exam. However, it's hard to do lung function tests in children younger than 5 years. Thus, doctors must rely on children's medical histories, signs and symptoms, and physical exams to make a diagnosis. Doctors also may use a 4â6 week trial of asthma medicines to see how well a child responds.
Diagnosing asthma generally includes a medical history, physical exam and lung tests. Asthma diagnosis is based on several factors, including a detailed medical history, a physical exam, your symptoms, and overall health and test results.
