Possible to have an Allergy without Symptoms?
Is it possible to have a positive blood test for a food allergen but not experience any allergic symptoms when the substance is ingested?
Absolutely. The blood test means only that you have allergic antibody to the food. This finding does not necessarily also mean clinical reactions to the food.
