Allergy Testing Next Week

We have DD's allergy/immunology appointment next week. I'd love to hear experiences from others on what to expect, what I should ask, etc. I also don't know what all they will be testing for or what I should request. We suspect problems (though not necessarily allergy...) with corn, beef, chicken, strawberries and oranges. I just don't know how it works and if they can specifically test for things I have concerns about.

I had ELISA testing for my family. Is that what you are doing?

I'm not sure what exactly they are planning. Her doc has mentioned both skin prick and RAST, maybe they are planning both? The letter from the med center said "plan to spend several hours with us" so I'm assuming it's much more than a blood draw.

OUr allergy dr. explained that they usually do the skin test first and based on what they find, do blood tests. It would require a lot of blood draws to test for everythign that they do on a skin test, so basically they will use the blood to confirm or get better results on anything you were allergic to on the skin, but won't have to waste blood on things that came up as negative on the skin.

It's my understanding that if you have specific things that aren't "normal" allergic foods, that you should talk to them ahead of time to see how you should go about this. We are going in Monday for additional skin testing for our son. They told me that they will test for whichever things I want, but if it's something that's not a typical allergen, they would need to know ahead of time. The smaller the kid, the less blood they can draw and the fewer tests that can be done with it. They are basically using the skin test to eliminate unecessary blood draws. Hope that makes sense.

The actual prick for the skin test shouldn't be too bothersome, but if your child is allergic, the itching can be very uncomfortable. All 3 of our children have gone through this over the past several months. The one thing I would suggest is to bring something that would be a big distraction as they are not allowed to itch and it will consume them unless you can get their mind off it somehow. For our tests, they had to wait 18 minutes after getting the initial prick and then the nurse would check the results. They put anti-itch cream on immediately after that, which worked wonders. For our 2 year old, we brought his favorite toy, a miniature basketball game that he can bounce the balls in. It was a perfect distraction. For our 8 and 10 year olds, we had to try different things. We mostly played rock, paper, scissors, which surprisingly worked great. When they were through with that, I told them to count backwards from 100 to 1 without getting distracted from what they were doing. It made them focus on that and forget a little about the itching. Two of our kids didn't seem to experience any more discomfort after getting the anti-itch cream; however, our older son was seriously allergic to some things and his welts didn't go away for a week. He had to take zyrtec, singulair and benadryl, along with using icepacks to relieve the discomfort. The allergist said this was not a typical response, but not abnormal either. Hopefully, yours will have the normal response, but wanted to let you know that they all handle it differently so you're prepared either way.

Personally, if you suspect any allergies or have food allergies in the family, I would have them tested on all the biggies, (wheat, milk, eggs, soy, peanuts and tree nuts, corn.... and I'm sure there are others), plus the ones you're concerned about already. I also had my kids tested for environmental allergies as I knew this was also an issue.

Good luck and hope some of this helps.

How old is the child?

I've been through allergy testing with all three of mine, and the approach often depends on the age.

If the child is really young (and small) they will do a RAST panel for most allergens. It actually doesn't involve "alot" of blood. My 13 month old just had a "complete" RAST panel - environmental and food, and they only took one vial.

The skin prick testing isn't nearly as bad as the intradermal testing, where they inject a tiny bit of the allergen into your skin. My two older two, as well as myself, have had that done. Basically... if the doctor "suspects" an allergy but it doesn't show on the skin prick test, they'll inject the allergen into the arm. However, if there is an obvious skin reaction, they won't further test it. An example... I had a tiny wheal where they tested for cat dander... but it wasn't big enough to be a positive. So, they injected me with it. And, it was very positive at that point. However, with feathers... my response to the scratch was so severe that they would not even consider injecting it.

It'll be the longest 15 minutes of your life, while you are waiting for the reactions and recheck. But, once it's all over with, hopefully it'll provide you some necessary answers, and can help you be proactive in your child's health!

Good luck!

Thanks so much for all the info! It helps to hear from someone who's been there.

She'll be 1 in two weeks so I'm glad we are finding all this early. I think the suspense is killing me the most. We already avoid most things we suspect, but I really want to know what she actually can eat.

If your allergist is anything like mine...they'll do a RAST test first. It's actually quite a bit easier on the child to have a 20 second blood draw, instead of the pricks on the back - and the waiting.

If there are issues that aren't addressed AFTER the rast, our allergist will then investigate further. Thankfully, with our little one (who had just turned 1 a week before his testing) the items that we "assumed" he was allergic to came back positive. And, we didn't need to go any further with the testing.

Lots of luck to you. Let us know how it goes.

      In the study linked above, the little girl switched to a gluten free diet and gained enough weight that that fat pad was replenished and surgery was not needed.   Here's the full article link...

      Fruits & Veggies

      Hello, @Jordan Carlson, So glad you're feeling better.   Tecta is a proton pump inhibitor.  PPI's also interfere with the production of the intrinsic factor needed to absorb Vitamin B12.  Increasing the amount of B12 you supplement has helped overcome the lack of intrinsic factor needed to absorb B12. Proton pump inhibitors also reduce the production of digestive juices (stomach acids).  This results in foods not being digested thoroughly.  If foods are not digested sufficiently, the vitamins and other nutrients aren't released from the food, and the body cannot absorb them.  This sets up a vicious cycle. Acid reflux and Gerd are actually symptoms of producing too little stomach acid.  Insufficient stomach acid production is seen with Thiamine and Niacin deficiencies.  PPI's like Tecta also block the transporters that pull Thiamine into cells, preventing absorption of thiamine.  Other symptoms of Thiamine deficiency are difficulty swallowing, gagging, problems with food texture, dysphagia. Other symptoms of Thiamine deficiency are symptoms of ADHD and anxiety.  Vyvanse also blocks thiamine transporters contributing further to Thiamine deficiency.  Pristiq has been shown to work better if thiamine is supplemented at the same time because thiamine is needed to make serotonin.  Doctors don't recognize anxiety and depression and adult onset ADHD as early symptoms of Thiamine deficiency. Stomach acid is needed to digest Vitamin C (ascorbic acid) in fruits and vegetables.  Ascorbic acid left undigested can cause intestinal upsets, anxiety, and heart palpitations.   Yes, a child can be born with nutritional deficiencies if the parents were deficient.  Parents who are thiamine deficient have offspring with fewer thiamine transporters on cell surfaces, making thiamine deficiency easier to develop in the children.  A person can struggle along for years with subclinical vitamin deficiencies.  Been here, done this.  Please consider supplementing with Thiamine in the form TTFD (tetrahydrofurfuryl disulfide) which helps immensely with dysphagia and neurological symptoms like anxiety, depression, and ADHD symptoms.  Benfotiamine helps with improving intestinal health.  A B Complex and NeuroMag (a magnesium supplement), and Vitamin D are needed also.

      @pothosqueen, Welcome to the tribe! You'll want to get checked for nutritional deficiencies and start on supplementation of B vitamins, especially Thiamine Vitamin B 1.   There's some scientific evidence that the fat pad that buffers the aorta which disappears in SMA is caused by deficiency in Thiamine.   In Thiamine deficiency, the body burns its stored fat as a source of fuel.  That fat pad between the aorta and digestive system gets used as fuel, too. Ask for an Erythrocyte Transketolace Activity test to look for thiamine deficiency.  Correction of thiamine deficiency can help restore that fat pad.   Best wishes for your recovery!   Interesting Reading: Superior Mesenteric Artery Syndrome in a 6-Year-Old Girl with Final Diagnosis of Celiac Disease https://pubmed.ncbi.nlm.nih.gov/31089433/#:~:text=Affiliations,tissue and results in SMAS.

      Wow! You're pretty young to have a diagnosis of SMA syndrome. But youth also has its advantages when it comes to healing, without a doubt. You might be surprised to find out how your health improves and how much better you feel once you eliminate gluten from your diet. Celiac disease is an autoimmune disorder that, when gluten is consumed, triggers an attack on the villous lining of the small bowel. This is the section of the intestines where all our nutrition is absorbed. It is made up of billions of tiny finger-like projections that create a tremendous surface area for absorbing nutrients. For the person with celiac disease, unchecked gluten consumption generates inflammation that wears down these fingers and, over time, greatly reduces the nutrient absorbing efficiency of the small bowel lining. This can generate a whole host of other nutrient deficiency related medical problems. We also now know that the autoimmune reaction to gluten is not necessarily limited to the lining of the small bowel such that celiac disease can damage other body systems and organs such as the liver and the joints and cause neurological problems.  It can take around two years for the villous lining to completely heal but most people start feeling better well before then. It's also important to realize that celiac disease can cause intolerance to some other foods whose protein structures are similar to gluten. Chief among them are dairy and oats but also eggs, corn and soy. Just keep that in mind.
