The information you give should be as accurate as possible. This will allow the doctor to get an overall picture about the issues affecting you. Prepare the information beforehand so you don't have to think of it off the top of your head at the doctor's office:  Any signs and symptoms of asthma (coughing, shortness of breath, noises during breathing, etc.) Past medical history (previous allergies, etc.) Family history (history of lung diseases or allergies with your parents, siblings, etc.) Your social history (tobacco use, diet and exercise, environment) Any medications you may be on (such as aspirin) and any supplements or vitamins you're taking The doctor might examine some or all of the following during your exam: your ears, eyes, nose, throat, skin, chest and lungs during the exam.

During this test, you will breathe into a mouthpiece connected to a spirometer that measures your air flow rate and how much air you can breathe in and out. Take a deep breath and exhale forcefully for as long as possible while the device takes the measurement. While a positive result confirms asthma, a negative result doesn't rule it out. This is similar to spirometry, and measures how much air you can exhale. Your doctor or a lung specialist may recommend this test to help confirm the diagnosis. To take the test, place your lips over the opening of the device and set the device to zero. Stand up straight and take a deep breath, then blow as hard and fast as you can in one breath.
