It depends: Some food allergies can be obvious in the first few months, if a baby reacts to a certain type of formula or new baby food. If this occurs (with vomiting, rash, or diarrhea), notify your doctor. Others may take longer to develop and may require blood tests or skin tests at a later age to identify them specifically.

By 6 months of age!: Ige allergy antibodies do not cross the placenta so when present are the infant's not the mother's. But the presence of allergy antibodies on skin or in blood is not the same thing as a clinical allergic reaction. False positives are common - especially true when eczema is present. This is one area where an experienced board-certified allergist can be uniquely helpful. Be wary of igg allergy tests.

Agree, but eczema and anaphylaxis usually occur independently of each other.

Discover, avoid : Food allergies vary in their intensity. If you are allergic, your body reacts to it in various ways.Skin tests can be positive and the blood can show elevated antibody levels. Elevated ige is important and means a major reaction is possible.Those foods must be avoided.If skin tests show some reaction but ige levels are low, the food may be tolerated. Discuss which foods to avoid with your allerg.
