Has anyone had their children tested for allergies? My son is 6.5 months old, and we already know he has a dairy allergy. We have a strong history of allergies in the family, some of which are food related, and are wondering if we should have him tested. I didn't know if there was a certain age at which this should be done. We just want to know ahead of time what he is allergic to, rather than finding out the hard way like we did with milk/dairy. Thanks!

Sorry to tell you that testing is NOT always reliable under age 3 (though my allergist said not ever reliable in anyone. 5% of people who are anaphylactic allergic to things test NEGATIVE on all tests). In our case, it is not. My dd (3 in March) and I both test negative to EVERYTHING, EVERY time, but we have very definate allergies. DD's anaphylactic to all traces of milk, seafood, shellfish, chamomile, sunflower, safflower; and severely allergic to ragweed, palm, strawberry, wool, lanolin, and grass. ALL of these we found out just by keeping track of reactions and watching for a pattern. Dairy, seafood, shellfish, grass, strawberry, wool, and lanolin were pretty easy to figure out as she had pronounced reactions from each one. Ragweed, chamomile, palm, sunflower, and safflower were more difficult. Palm was a process of elimination of ingredients (in her soy cheese); and the rest (all members of the asteracea family) we found out in Nov. when she had an ana reaction to a cup of chamomile tea. Allergist said eliminate ALL members of that family b/c ragweed was a huge player in it. Since we have her eczema is GONE for the first time in her entire life. Keep a food diary and a reaction diary. Also, check out the FAAN site, www.foodallergy.org and www.godairyfree.org for more info. Good luck to you!

My daughter is now 3. She was tested for allergies at around 15- 18mo. They came back negative except the egg. She is allergic to dairy, peanuts, some fish, eggs and most recently a caterpillar. (Weird I know) But the tests are garbage at that age. My daughter is horribly allergic to these things and I dont need a test to prove it. I can see it. A friend of mine had her baby tested under a year and she tested positive for a dairy allergy but now at 1 1/2 she will give her dairy once in awhile and she does fine. While my daughter tested negative but has very severe reactions to the tiniest bit of dairy....



You should know that there are different kind of allergies. IgE allergies are the ones that can be anaphalactic and have a quick reaction. like within minutes of exposure. IgG allergies can take a half hour to a day or so for the reaction to kick in and they are hard to test for. Most allergy tests only test for IgE allergies. To make it more complicated there are IgA allergies and other kinds too. So use the test as a tool but dont rely to heavily on it. Try an elimination diet. Can be tricky but you will find out what is causing symptoms with no lingering mysteries.

Just had allergy testing done by an allergist for our 13 month old. I was very happy to find out that they were not using needles, they put drops on his back and we had to keep him still so the drops would not run. Found out that he is definately allergic to milk and components in it.






are you sure they didn't use a needle? that sounds like a skin prick... they put a tiny needle to put the liquid






Nope - definitely not a needle.  There was a dropper for each of the items they tested.  The hardest part was keeping him from running around and having the drops run.

I would say to force the issue with your ped. My son's doc told me that allergy testing isn't usually done until after 1 year because babies are so sensitive to everything and often grow out of allergies by age 1. But if you are concerned about further allergies, or if you think they may be life-threatening, definitely insist on it. To put your mind at rest if nothing else.
To do your own improvised version of allergy testing you can rub your fingers across a small patch of his skin then dab milk or peanut butter or another allergen on the area and watch for hives to flare up, then wash it off quickly. My son does his own allergy testing, he rubs his food around his face when he feeds himself and when hives pop up I know the food he just ate was an allergen and avoid giving it to him again. The hives fade within a minute or two of wiping off the offending food, and really it's no different than a skin-prick test but without the pricking, and not as sterile since a peach could cause a reaction from being cut on the same cutting board as a peanut. So long as you are careful of cross-contamination it could be an effective way to eliminate certain foods before he ingests them.

My daughter is 11m old and was told that she was too young to get a allergy test done. Also that the blood test is not accurate. I went to my daughters pediatrician and he just said its an allergy just give her Benadryl and out the door. We took her to a dermatologist and some cream and something close to Benadryl but better so she said. My baby has been suffering with this for 3 weeks now and we don't know where to turn now.

My son is now 3 years old. three days after his birth the doctors said he had a milk allergy and started him on soy formula. he was on soy for three years of his life but a few days ago. we got results from a blood allergy test saying he was allergic to soy. i say yes get tested as soon as possible. you don't want to give your baby something for years only to find out later on that you could have killed your child by just feeding it.

Hi, yes, my daughter had a food allergy test at 9 months old (we are waiting for the results). I insisted on it in the end because the whole trial-and-error was killing me: I would literally stand by her with my heart thumping like crazy every time she tried something, and I was starting to feel very stressed about it. I decided I was no longer happy to try things and wait to see if my child would puff up like a balloon or stop breathing so we did the test. Like yourself, we already know milk affects her and we were also told that if she has this, then it is "likely" she will be allergic to "some foods".

Its about as upsetting as a vaccine: strap on arm, needle, needle stays in for a bit as they draw blood - some screaming from baby but she forgot very quickly (within a minute) and became engaged with a musical book.

My son is 19 months old & we just got the blood test yesterday. We are waiting on results. Our last doc brushed me off about absolutely everything, including food allergies. We now have a new doc & I LOVE her so much. She is doing a lead test, an anemia panel, & the food allergy testing. She also actually did a complete head to toe assessment on my son, which our old doc NEVER did. She said developmentally he is right on track.

As for my son's food allergies, he has a mild reaction to oats, barley, coconut, & rooibos tea. But he has a severe reaction to pumpkin. I am anxious to see what the testing shows. I really don't understand how it works.

My youngest just turned 9 months and I'm getting his blood test done as soon as the failed atempted blood draw heals. the skin test can give you false positives the blood test also gives more info on the severity of the allergy so if you are given a choice when you do get the test done I recommend the blood test. We had both done on my oldest and got fewer positives with the blood test. Also depending on how much they test for the skin test can be very traumatic its a single needle prick for each allergen. My son was stuck with at least 70 needles when he had the skin test done at the age of 4 my husband had to hold him down while this was done to his back.

I knew we had a dairy issue with my daughter as well, when she was only 2 weeks old, luckily I was breastfeeding and could eliminate dairy from my diet and she did wonderfully, but when we tried to introduce it again at one year she reacted again, My Dr. just fluffed us off and said they do not do testing before 2 years, but I kept pushing, and she refered us to a great ped. Allergy specialist. Our very first appointment he did testing, she was 15months old.. ( small skin pricks on her arm) .. then we went back for additional "patch" testing that was not invasive at all. just a reservoire patch on her back with milk in it and she wore that for 2 days ... She was not bothered by any of the testing, and It was finally good to know excatly and have a diagnosis that she was allergic...I'm glad that I was firm in my standing my ground and wanting a referal to a specialist... My fam.dr. was quite surprised at my next followup when I informed her she had testing done and she was allergic....

Our allergist tested my daughter at 4 months. Her brother has many severe allergies and we wanted to know right away which major allergens to avoid. The dr. said normally they wait until they are 1 but w/ a family history of severe allergies they test earlier. They only did the skin prick test on her.

I had to go to a chiropractor that does natural medicine. he has tested my seven month old daughter. we have caught all the allergies before we gave it to her. he was also able to tell us if it was an allergy or intolerance.... i personally am allergic to just about everything so it was important for us to find out.

When my son was a baby, a regular doctor did the basic RAST test, which tested 8 (I think) of the most common allergens. It is done by drawing blood. When it came back, he referred us to an allergist. Later, the allergist waited until our son was four to do skin testing on his back. Then we switched allergists, and he prefers the RAST testing, but a more comprehensive testing of suspected food and environmental allergies. From what we heard from our doctors, it sounds like there are varying medical opinions on what testing to do at what age. In the end, for us, all the tests pointed to the same allergies.

My son is 2 1/2 yrs old. His doctor did a blood test for allergies just after he turned 1 because he had obvious allergic reactions to milk. She rolled it in with some other blood test that they do (I believe it was an iron test), although she said that they normally don't do it that young.



Before the test, she asked me if there were any specific things that I wanted to test for (she had a list of common allergens). In addition to what I requested, they also tested for nuts, eggs and some other very common allergens.



I was completely shocked when I went back for the follow-up appointment and found out that he was not only allergic to milk but also peanuts. Actually, she said that just because he tested positive with the blood test does not mean that is allergic (but later we found out that he is). She recommended that we avoid milk and peanuts until after we saw an allergist. She also recommended that we wait until he was 2 to see the allergist (since you should avoid peanuts until 2 yrs old anyway). The not knowing was torture, so we ended up taking him at about 1 1/2 yrs.



The test itself wasn't too bad. With young children they do the skin prick on the back. The hardest part of it was getting him to hold still for the 15 minutes or so. The allergist said that most children that have one food allergy have more than one food allergy.

I had my daughter tested before she was 1. Was breaking out in hives with certain foods. Come to find out she was allergic to dairy, eggs and peanuts. I would request to see an allergist. With a family history of allergies I'd rather be safe than sorry!

Yes, the age is 6 months. We just went through this with my granddaughter. We have an extremely allergenic family. My daughter talked with our allergist while she was still pregnant to give the baby the best chance to not have allergies. She took her to see the allergist at just a couple months, but she needed to grow bigger to have enough skin area to do the tests. Take him to a doctor who is just an allergist not a doctor who does something like ear/nose/throat and says he does allergies too. Good luck. With the allergist guidance we got our grandaughter through some foods sensitivity problems. She is now 2 and has no allergies or sensitivity problems either.

Yeah it's an allergy. The doctor said he knows it's an allergy as opposed to an intolerance because any time it comes in contact with his skin, he breaks out into huge red welts which wouldn't happen with an intolerance since that's more of an internal digestive type thing.
