Understanding Allergen,Individual - Food Onion Piaz (Allium Cepa)

What is Allergen,Individual - Food Onion Piaz (Allium Cepa)?

Allergen, Individual - Food Onion Piaz (Allium Cepa) is a blood test that helps detect an allergy to onions. When you consume or come in close contact, the body misinterprets onions as invaders. The immune system releases Immunoglobulin-E (IgE) antibodies to protect the body against the allergy-causing substance (called an allergen), onion. This test measures the total IgE antibodies in the blood and identifies an allergy. The allergic symptoms to onion include rashes, itching, headache, swelling of the lips, tongue, and mouth, nausea, diarrhea, gas, stomach pain, dizziness, and anaphylaxis (very rare). Watchful eating and avoiding foods containing onions, including salads, dressings, sauces, etc., is the best way to prevent such an allergy.

Interpreting Allergen,Individual - Food Onion Piaz (Allium Cepa) results


* If your total IgE level is increased, it usually indicates that you are suffering from one or more allergies. Sometimes, increased levels are also associated with parasitic infections. * An elevated IgE indicates an allergic process but does not indicate what a person is allergic to. In general, the greater the number of things a person is allergic to, the higher is the IgE level.
