Can you test for nocturnal asthma by measuring the airflow out of the lungs?

ANSWER

You can test for nocturnal, or night time, asthma by measuring airflow from your lungs. You exhale into a device called a peak flow meter in the evening and again when you wake up. If your peak flow drops by more than 20% between night and morning, you may have nocturnal asthma.
