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.
There are some key asthma tests your doctor will use in diagnosing asthma. Some asthma tests, such as lung (or pulmonary) function tests, measure lung function. Other asthma tests can help determine if you are allergic to specific foods, pollen, or other particles.
