I have been hoping for several years to have the kids allergy tested but have not had the financial resources (or insurance) and access to testing at the same time until now. When I discovered that there was testing available in-country, I slowly moved it up the priority list until we were able to take all four kids and get it done.
As background, we have two children who took two years to potty train, due to food sensitivities that I suspected were allergies (their allergies present as digestive issues), and ZL, in particular, but all of our children, really, have had more severe diaper rashes, obviously related to what they'd been eating. I really wanted to know what was necessary to avoid and what we didn't have to worry about, so off to the doctor we went.
Here is the list of allergens we returned with. The asterisks indicate severe allergy.
Although we have not had an anaphylactic reaction to date, the doctor was concerned enough about MS's and ZL's egg white allergies that he asked us to have Epi Pens available for them. An severe allergen can cause a reaction the 1st, 100th or 1,000th time it is ingested, so we chose to play it safe and have my dad bring two Pens with him when he came to visit recently (brother-in-law doctors and hometown, friend-owned pharmacies are really a blessing).
At this point, we're avoiding all allergens (as much as possible, because occasionally we forget). We may do this for up to three months, so that their systems can be clear of allergens before we start re-introducing and looking for reactions.
We have purchased Rice Milk (mainly for MA to use on cereal; ZL still eats his dry when we have it) and started using flax meal and water as an egg replacement and have begun picking cheese off of pizza. Not simple, but not the end of the world, and we are hoping for fewer stomach aches and diaper rashes as a result.
