How accurate is igG and igE testing?
My son has had eczema since he was one. He is now almost two and a half. After going the natural route for more than a year, I had to finally succumb to steroids for 15 days, and now that my son is off them, his eczema is flaring again. My son has a diagnosed dust mite allergy, but according to the skin prick test at Kaiser, he does not have allergy to mold, wheat, dairy, egg, tomato. He has not yet had any other allergy testing yet. We have gotten an IQAir filter to clean the air in his room, along with a dust mite cover for his organic mattress. We have gotten rid of the stuffed animals because they harbor dust mites, cleared out his room so that there is no clutter or upholstered furniture in it. We still live in a carpeted rental house and are looking for a house with hardwood floors, but it may be more than a year before we can move. Our son has obvious gut and detox issues that we are working on.
In our course of natural treatment, we have used organic butters/oils (shea, castor, jojoba, hemp, rose hip, argan, tanamu, tallow balm, coconut, olive oil) and later had to use more conventional creams like Aveeno baby eczema, Cerave and Vanicream. We have used probiotic spray, soap nuts for laundry, goat milk soap, bentonite clay, cilantro baths, epsom salt baths, probiotics like Prescript-Assist and Jarrodophilus), fermented foods (and then later, a low-histamine diet), turmeric/garlic/ginger/, vitamin D (from sun and supplement), keeping house clean, washing sheets in frequently in hot water, drinking filtered water, filtering chlorine from the shower water, omega 3's, gelatin, organic chicken livers, bone broth, ACV, lemon water, green smoothies/juices, fermented cod liver oil, organic cotton and cotton clothing, clean/organic/grassfed/pastured/wild diet of veg/fruit/egg yolks/meat/chicken/fish. Our son is also gluten-free and dairy-free to help with his inflammation. There are several other things we have tried, but it's hard remembering them all.
Recently we went to a naturopath for the first time. Paid $600 out of pocket (Kaiser does not reimburse) for a 1.5 hour appt. only to hear maybe 10-15% new info that I had not yet come across while researching myself. The new things we are trying at her recommendation are borage oil and zinc supplements. The ND also recommends igG and igE testing. Was confused about the igE testing because the ND says that a person does not have to try one of the foods on the igE test before testing positive for an allergic reaction. (My child has not yet tried oats orally-- only oatmeal baths). However, it was always my understanding that in order for an allergic reaction to show up, you need to have had the food at least once. Would appreciate any feedback on how helpful those tests were in your experience before we invest in them, or would appreciate more eczema or dust mite allergy tips. Thank you so much in advance.
