Allergy Test 

Allergies are caused when your immune system overreacts to a foreign substance, such as pollen or pet dander. This overreaction can cause various symptoms, including sneezing, itching, and watery eyes. In some cases, allergies can lead to more severe conditions, such as asthma. If you think you may be allergic to something, you must talk to your doctor and get an allergy blood test. An allergy blood test is a screening tool used to determine whether a person is allergic to a particular substance. The allergy blood test is usually ordered when a person has symptoms suggestive of an allergy, but the cause is unknown. There are three main allergy blood tests: CBC, AEC, and IgE. 
  • CBC is the most common type of allergy blood test and is often used to screen for allergies to food or airborne particles. 
  • AEC is a more sensitive test and is often used to confirm an allergy diagnosis. 
  • IgE is the most sensitive of the three tests and is used to diagnose allergies to substances that are not airborne, such as venom from a bee sting.
Allergy blood tests are generally safe and have few side effects. The most common side effect is mild discomfort at the injection site. Avoid consuming anti-allergy pills before your blood test. Note: You should avoid anti-allergic pills for 24 hours before taking the blood sample.
