Allergen-Onion, is a blood test that helps detect an allergy to onions. It measures the level of antibodies called Immunoglobulin E or IgE. An increase in IgE is an indication of an allergy. Onion allergies vary in intensity from mild to severe. Symptoms include rashes, itching, headache, swelling of the lips, tongue, and mouth, nausea, diarrhea, gas, stomach pain, dizziness, and anaphylaxis (very rare). Mild symptoms resolve once the onion gets discarded through the digestive system. Avoiding onions is the best way to prevent an allergic reaction. 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.Read more
