The ELISA blood test is used to test immune responses in the body. It is widely used to detect antigens that cause allergic reactions. ELISA is a very specific test that can determine the amount of a substance (antigens) in the blood. Levels of the antigen are made to decide whether the amount differs from a normal amount, and this shows a positive or negative result. This test can help doctors identify infections, allergies, or confirm a pregnancy.Consider meeting with one of our dieticians if you have a food allergy.
