Asthma: Steps in testing and diagnosis

Physical exam

Your doctor may:

  • Examine your nose, throat and upper airways.
  • Use a stethoscope to listen to your breathing. Wheezing — high-pitched whistling sounds when you breathe out — is one of the main signs of asthma.
  • Examine your skin for signs of allergic conditions such as eczema and hives.

Your doctor will want to know whether you have common signs and symptoms of asthma, such as:

  • Recurrent wheezing
  • Coughing
  • Trouble breathing
  • Chest tightness
  • Symptoms that occur or worsen at night
  • Symptoms that are triggered by cold air, exercise or exposure to allergens

Asthma signs and symptoms in children

In children, additional signs and symptoms may signal asthma. These may include:

  • Louder or faster than normal breathing
  • Frequent coughing or coughing that worsens after active play
  • Coughing, clear mucus and a runny nose caused by hay fever
  • Frequent missed school days
  • Limited participation in physical activities
