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.
Asthma in children can often be diagnosed based on medical history, symptoms, and a physical exam. Keep in mind that oftentimes when you take your infant or older child to the doctor with asthma symptoms, the symptoms may be gone by the time the doctor evaluates the child.
