Tests and exams
The most common way to diagnose asthma is to have a lung function test. The doctor will also want a personal and medical history. An allergy test may be needed. This is because many asthma symptoms are triggered by allergens.
There are many ways for doctors to find out what triggers your allergies. A skin test is the most common. A small amount of allergens are placed on the surface of the skin to monitor the skin’s reaction. An allergy will show by a swelling that looks and feels like a mosquito bite. Because asthma is often triggered by allergies, it’s important to know what those allergies are. This can help the doctor make an asthma prevention plan.
During a peak airflow test, you hold a device called a peak flow meter to your mouth and breathe into it as hard and fast as possible. Peak flow meters can be used at home to help monitor your asthma.
