What does allergy testing involve?
The test involves placing a small amount of the suspected allergy-causing substance (allergen) on the skin (usually the forearm, upper arm, or the back), and then scratching or pricking the skin so that the allergen is introduced under the skin surface.
How long does it take to heal from an allergy test?
The test sites disappear in as little as a few minutes or as long as 12 hours after the test is complete. You can take an allergy medication (like Benadryl® or Zyrtec® ) to help with any discomfort. For severe allergic responses it may take 2 to 3 days for the bumps to disappear, but they should not hurt.
