Possible to have an Allergy without Symptoms?

04/10/2009

Question:

Is it possible to have a positive blood test for a food allergen but not experience any allergic symptoms when the substance is ingested?

Thank you.

Answer:

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.
