Types of Allergy Blood Tests. Allergy blood tests detect and measure the amount of allergen-specific antibodies in your blood. When you come into contact with an allergy trigger, known as an allergen, your body makes antibodies against it.llergy blood testing is recommended if you: 1  Are using a medicine known to interfere with test results and cannot stop taking it for a few days. 2  This would include antihistamines, steroids, and certain antidepressants.
For environmental allergies such as pets, dust mites, pollen, and molds, skin prick testing is the best test to help with diagnosis of allergy. Blood work looking for the allergic antibody (IgE) is less sensitive and may miss some allergies.
