A visit to your doctor or allergist is the most accurate way to test for allergies. That's because your healthcare practitioner will offer a more thorough approach to testing, including asking about your symptoms and performing a physical exam. Based on these assessments, your doctor can decide which test is appropriate. That could be a skin prick test or blood test.
Like the at-home allergy test, a doctor's blood test will look for the presence of IgE antibodies.
A skin test can be performed with a referral to an allergist. This test is performed by pricking or scratching the skin with small needles to document your skin's reaction to potential allergens.
