- Asthma diagnosis tests measure your ability to inhale and exhale, determine the sensitivity of your airways and ascertain whether other conditions may be causing asthma-like symptoms.
- Lung function tests, such as spirometry, are the primary asthma diagnosis tests, but allergy testing, bronchoprovocation tests and chest X-rays may also be performed.
- Spirometry tests involve blowing into a special device that measures and records the amount of air you can breathe in and out, and the force and speed with which you exhale.
- Asthma diagnosis tests enable doctors to identify asthmatic patients and begin treatment before the disease worsens.
- Asthma testing is less accurate and very difficult in children younger than 5, which leaves medical history and symptoms as the only diagnostic tools available.
