How old does a child have to be for an allergy evaluation?
Most allergic disease in children under age two years is caused by foods and the common household allergens of dust, mold and animal dander. If your family doctor or pediatrician suspects allergy and is unable to control the problem through environmental means, dietary manipulation or medication then he/she may make a referral to the allergy clinic. Skin testing is rarely positive prior to age six months, but an allergist may be able to assist in treatment of allergic or respiratory problems in young infants less than six months of age.
