Food allergy blood test
If a child has a food allergy, blood tests are often recommended by doctors. Such allergies are usually treated by the child’s pediatrician or might be referred to an allergy specialist. If the symptoms recur continuously, the doctor asks for a skin-prick test, particularly for small babies. This test recognizes the allergens on the top layer of the skin, which swells up in a short period of time. Radioallergosorbent (RAST) blood test is also preferred to measure levels of specific IgE, directed towards food in the blood.

Baby food allergy treatment
The only sure treatment for food allergy is to avoid the particular food for some time and introduce it once or twice later to see whether the child develops a food allergy again. Sometimes doctors recommend epinephrine auto-injector to provide an emergency shot. If your baby becomes allergic to breast milk, the mother is advised not to consume certain items and see if the baby then becomes immune or continues to have problems.
