I have discovered, much to my dismay, that allergy testing does not always provide clear-cut answers. I'm sure those of you who have dealt with allergies, whether seasonal, food related, drug related, latex, insect, r other have found the same frustrations in the process of trying to diagnose and cure (I use this word rather than treat because I feel that many allergies
are curable). Add that to the fact that not everyone agrees about the approach to take in dealing with allergies, and a parent can become pretty confused. In our case, I am thankful to be able to ask and trust God for His wisdom and His direction in the way that we should choose to deal with allergies and food sensitivities that we've seen in Reagan, Adam, and sometimes even Lincoln.
Our family physician was the first (2 1/2 years ago) to suggest that we try to find the source of Adam & Reagan's eczema rather than continue to use topical steroids to treat.
"Accepted" Allergy diagnostic tools (medically "accepted" - we've 'used' the ones in orange):
- medical history (family, observed responses, general state of health)
- blood tests (RAST is medically mainstream, identifies IgE response)
- prick skin test (identifies IgE)
- food challenges (physician observed response to eaten foods)
- elimination diets (take out foods groups for weeks & reintroduce in order to observe a reaction)
"Other" Allergy diagnostic tools (not "accepted" by mainstream medicine - we've 'used' the ones in orange):
- Applied Kinesiology Testing (usually done by naturopaths)
- Body Chemical Analysis (aka - saliva testing also done by naturopaths)
- Pulse Testing (increased heartrate after exposure to allergenic foods)
- ELISA Blood test (measures IgG - our allergist ignored this info as useless although our family dr is who prescribed it)
Whoa! The amount of options just leaves one's head spinning! We have used many naturopathic tests, which told us that they were 'sick' as well as the ELISA blood test for Adam and Reagan and got some
results which seemed normal (having observed the kids react to certain foods) and some which seemed odd (or just plain wrong - like the fact that an observed allergy to peanut did not show up or the positive response to mung bean, which none of us had ever eaten...do you even know what they look like?). We've since learned just how complicated the immune system is and how much test results can vary! Although I read much about IgE, IgA, IgG antibodies produced by the body for whatever reason (external contaminants such as pollen or bee stings, or particles of food that are to large to be used in the blood and have 'leaked' through the gut wall), I still struggle to keep it straight.
About 50-60% of all skin and blood tests are false positives. These results occur for two reasons:
•When you eat a food, your digestive system gradually breaks down the food proteins, chopping them into small pieces. But diagnostic tests can’t mimic this allergen-reducing process. Since food proteins are bigger when they interact directly with your skin or blood, it is easier for the IgE antibodies to “see” and attack them. As a result, your tests may show that you are more sensitive to a suspect food than you really are. Thanks to the digestive process, the allergenic proteins are small enough to fly under the IgE radar—and the food is safe for you to eat.
•Members of a food “family” often share similar proteins. For example, if you are allergic to peanuts, your tests may show a positive response to other members of the legume family, such as green beans, even if eating green beans has never been a problem for you. This is known as cross-reactivity. The test is positive because it recognizes a similar protein in peanuts and green beans. But the test is not detecting the real culprit—an entirely different protein found only in peanuts." [emphasis mine]
Well at least that let's us know some reasons
why we get such inaccurate results from allergy testing. It's really quite dissapointing for us because it means that we have to be even more diligent in observing our kids and their responses to the foods they eat. And it doesn't help us to understand what is and what isn't a false positive. So even with a blood test, we are stuck with our best 'guess' based on observation and medical history.
And an excerp from a different perspective (yes - we are
those kinds of nutty people) on diagnosing and treating allergies than the mainstream medical community generally accepts - working to heal the gut to get rid of food allergies...
From Dr. Natasha Campbell-McBride at the GAPS diet website (not mainstream):
"Many people try to identify which foods they react to. However, with damaged gut wall they are likely to absorb most of their foods partially digested, which may cause an immediate reaction or a delayed reaction (a day, a few days or even a couple of weeks later). As these reactions overlap with each other, you can never be sure what exactly you are reacting to on any given day. Testing for food allergies in notoriously unreliable: if one had enough resources to test twice a day for two weeks, they would find that they are "allergic" to everything they eat. As long as the gut wall is damaged and stays damaged, you can be juggling your diet forever removing different foods and never get anywhere. From my clinical experience it is best to concentrate on healing the gut wall with the Introduction Diet [this is the first stage of her recommended dietary approach to healing allergies through the gut]. Once the gut wall is healed, the foods will be digested properly before being absorbed, which will remove most food intolerances and allergies." [emphasis mine]
So we have a history, a blood test (albeit not current - at this point I don't want to spend the money for something so unpredictable anyway), a skin prick test (just last week - I'll post the results later), and now a plan of attack (Gut And Psychology Syndrome Diet). I know that some find it strange that we aren't just dosing the kids on Zyrtec and cortisone and leaving it at that, but I don't really care what others think. We are
more than willing to use these remedies if we are led that direction. But until then, we will attempt to make them healthier from the inside out and hope and pray that their symptoms decrease or dissappear altogether.
The Gut and Psychology Syndrom diet is usually used for cases far more serious than ours - autism, depression, ADD, dyslexia, dyspraxia, and schizophrenia - but is recommends for people with continual eczema, asthma, and known food allergies. It is very, very strict and depending on the individual, may take many months to help the gut get back into a better state of bacterial
balance health which is what we feel will actually help our children. We are thankful that we are already in a place that makes it easier for us to implement it than we ever were before we started eating and cooking whole, healthy foods. I know I could never have gone from using Campb.ells and CoolW.hip right into this diet (goodness knows it's taken me all 12 years of my marriage and I'm still figuring out this cooking thing)! Still, it will be
nearly impossible and full of stress quite difficult for us to eat out of the home in situations with family or at 'away' school or any other fieldtrip that takes us from our kitchen (can you tell I'm nervous about this part?).
However, I am
so optimistic about this new diet! I hope that our efforts will be God led and blessed with fewer allergies in the future so that years from now the kids won't have to worry about their hurting tummies and itchy skin, nor be diagnosed with worse conditions, like asthma. For
now, I can handle the complaining children, the extra time in the kitchen, and the eyerolling friends. Even if it doesn't do what we expect it too, is it wrong to be eating more healthily...learning to be better stewards of our bodies?
After all, my children are a heritage from the Lord - they are worth it!
