What allergy tests are used to find the cause of breathing problems?

ANSWER

One commonly used allergy test is the prick technique. In this test, the doctor first puts a tiny drop of allergen on your skin. Then the doctor makes a puncture with a needle directly in the drop of allergen extract. If you are allergic to the specific allergen, your body will react to it by turning red at the site. You may also experience itching and swelling at the site of the allergen placement. Another type of skin test involves your doctor injecting the allergen extract directly under the skin using a syringe. Other allergy tests include:

These tests are used less frequently than the skin testing.

  • Allergy blood tests (called a RAST or radioallergosorbent test)
  • A challenge test, in which the doctor introduces tiny amounts of the suspected allergen by inhaled, oral, or other routes
