How do I know if I have allergies or asthma?

How might I get diagnosed with asthma or allergies? How can I avoid symptoms?

A board-certified allergist can help perform asthma and allergy testing. Lung function testing, like spirometry, is used to diagnose asthma.

Allergy testing can include a skin prick test, patch test, or blood test.
For both conditions, your doctor will conduct a physical exam. They will also ask questions about your medical history and symptoms.

Taking asthma and/or allergy medicines as prescribed will help avoid symptoms. Identifying your triggers and developing strategies to reduce them will also help. Both should be part of your management plan. Work with your doctor to find a treatment plan that works best for you.
