blueleopard and others: Need advice on allergy testing
I have an appt. with an allergist next week. I want to go there with all the knowledge I can gather. K has had a basic blood test which showed positive for Milk and Walnuts. From what I have been reading it seems like both the blood and skin prick tests are not very accurate when it comes to food intolerances. Is there any point in doing the skin prick test? Even though the blood test showed milk allergy, K can tolerate yogurt (she just can't have milk or cheese). How does a child tolerate skin prick testing? My K is 19 months old and has extreme anxiety towards docs and strangers. How is it done. Do they put them on their tummy and start scratching/pricking on the back and then how do you keep them sitting still for 15 mins or whatever it takes to get results afterward? I am sure it is very itchy if there is any reaction. What is the patch test? Do you wear the patch and then check the reaction at home? Not sure if all allergists offer this option. Sounds like this would be a better test for food intolerance issues. With K, it is always a slow reaction. 1 tsp of new food usually is ok the first night but the next night she will start waking up every 1/2 hour to 1 hour. Thanks for any info on allergy testing!

Lorenzo b.4/25/07 1 week in NICU w/ aspirate pneumonia from a reflux episode; diagnosed GERD at 9weeks; Used Zantac for 5months. Currently using Chinese Medicine and Craniosacral Therapy. GERD, Obstructive Sleep Apnea, Sensory Processing Disorder. Ask me about breastfeeding a refluxer! Pic: day 5 in the NICU.
I'm no expert on this, but I have also been warned of limited accuracy with the allergy testing and have been told that the best way to confirm or deny the presence of allergies is to eliminate potential offenders for 4-6 weeks. It seems like the value of allergy testing may be to help guide the process of elimination...but as I said, I'm no expert, as we are just getting started on this process of exploring allergies ourselves...

Pictured: G'mom w/3 kids. I'm mom to 1 angel Melissa (dec'd 11/92 - hypoplastic left-heart syn.)
2 healthy daughters (knock wood) Cory (16), Kim (11) & Eric (4) diagnosed with e.e. (scoped 8/08), GERD & severe food/seasonal allergies, asthma. Cried non-stop first 17 mths. of life Found out he is allergic to cow's milk, soy, eggs, and peanuts. Takes Prevacid, Neocate One Plus & Flovent.
Eric's had it all. From local allergists and Children's Hospital of Philadelphia. As a matter of fact, he just had another round on Friday (at CHOP). They did scratch testing only. This will look for IgE allergies (immediate). He was tested for environmentals/pets/certain foods. The foods were negative; pollens/grass/cats/dogs were positive. He has tested positive to nuts, eggs, dairy in the past - we did not repeat. Blood work in the past confirmed these positives, although I believe scratch testing is more accurate. HOWEVER, these tests will not pick up delayed type reactions to food common with EE, nickle in jewelry or certain other chemicals. This is where patch testing can be helpful. They put the patches on Fri., come back to the office and remove on Monday. Eric tested positive for rice, potatoe (white), peaches, & corn. From what I recall, this is a helpful tool, but not nearly as accurate as scratch testing is for IgE allergies. The scratch testing is a bit uncomfortable, but not unbearable. After a little bit of the allergen is put into the skin, the child must wait about 10 mins. to see whether or not a welt forms & then it will be measured. For example, Eric scored a 4 to peanuts (0 - 4 is the scale), so he is pretty allergic. All that being said, other types of intolerances exist. For example, lactose/fructose intolerances. These are not true allergies. Also, eliminating a food to see if a problem clears, then reintroducing to see if trouble starts (1 food at a time for weeks if necessary) isn't a bad idea. That is the way we trial foods with Eric's EE. Even if he seems to pass a food, however, we still have to scope to see if the little white monster blood cells (eosinophils) have returned to attach his esophagus. But, that is the nature of EE. Hope this info. helps. El
