What does a negative bronchodilation test mean?

A negative bronchodilation test generally indicates that the patient's respiratory function is normal. A negative

bronchodilation test indicates that the patient's respiratory function is basically normal, and there is no obvious airway obstruction or airflow restriction. It can initially rule out the possibility of asthma and other diseases. However, it should be noted that a negative result does not completely rule out the possibility of all respiratory diseases. It is also necessary to make a comprehensive judgment in combination with other test results and clinical manifestations.

It is recommended that patients with positive bronchodilation test and uncomfortable symptoms should see a doctor as soon as possible for examination and treatment.
