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.
Tests for asthma. There's no single test for asthma, but it can usually be diagnosed from your symptoms and some simple breathing tests. Your GP will often be able to diagnose asthma. But they may refer you to a specialist if they're not sure what's causing your symptoms.
