Is a class 3 peanut allergy something to worry over? My son is 3 and he has been having some tummy problems. His GI ordered some blood work for food allergies. It came back as a class 3 peanut allergy. A week before he had a skin test for allergies and al

In brief: Workup/mgt

I would suggest avoiding all peanut products including peanut oil and observing whether the symptoms resolve.
The test called a CAP test can then be repeated at that time. Children who are allergic to one food may be allergic to other allergens as well. There was a study that indicated faucets in public and at schools are one source of peanut contamination, so the surfaces should be cleaned.

In brief: Peanut Allergy

It is only as significant as his reactions.
If he gets tummy probs every time he has a peanut product, then i would avoid. If he has never had anaphylaxis or any serious reaction, then your concern should not be on the class 3.....

In brief: A

A blood test showing class 3 sensitivity to peanut needs to be interpreted with caution.
If your son's total ige is elevated the significance of the blood test is weakened, especially in view of the negative skin test. Having the positive blood test and his ongoing abdominal upset, you may wish to avoid peanut in his diet for 3 or 4 weeks to see if there is improvement. If there is no benefit from this then you would want to re-introduce the food as avoiding it long-term may lead to allergy. There are some shared protein allergens between grass pollen and peanut which could be a another explanation for the blood test. The "gold standard" for food allergy relevance is what happens with avoidance and then with re-introduction. If your son has asthma or any history of life-threatening allergic reactions you may want to have an emergency plan i.e. Epi-pen (adrenaline) and consider having him eat peanut for the first time after the avoidance period at your allergists office (of course you should discuss the proposed plan with them).
