Doctors will often be able to diagnose asthma by listening to your symptoms and listening to your chest. No fur ther tests may be required. If there is doubt about the diagnosis, the doctor may give you a small plastic device to use at home called a peak flow meter. This is a device that you blow in to, and it measures flow of air thr ough the bronchial tubes. If there is a decrease in the measurement expected for your age, or if there is a large variability in the measur ements between different times of the day, this suggests that you have asthma. Other special breathing tests may be required, and are performed in a special lung function laboratory in the hospital. When doing these tests, you will be asked to breathe in and out, through a mouth-piece, into a device that measures how narrow your bronchial tubes are. In the same laboratory, skin allergy tests can be performed to assess if you are allergic to cer tain things, suc h as house dust mite and pollens. Blood test and x-rays are sometimes required
