Anybody Have a False Allergy Test?

Actually, I just took my son to the allergist yesterday to get a prick test (he's two). Last year he was given a blood test for allergies and found out he was allergic to eggs. I found this odd because he had eaten eggs and egg noodles in the past and never had a problem. Plus my mother-in-law accidentally fed him french toast after the test was taken and still no reaction. So for the past year, we have been avoiding eggs and anything with eggs in it (such as cookies, pancakes, etc). Then my son had a liking to blueberry pancakes and we tried it and watched him-- again, no reaction. Since the season of the flu shot is here, his doctor decided to have him go to an allergist to test the egg allergy again. After painful poking, we found out that not only is he not allergic to egg, but probably never was. The allergist let me know that it is common for blood allergy tests to come back with a false positive (meaning that it says they are allergic, when indeed they are not). -- I was quite frustrated to hear about this because my son is a very picky eater and to take away the few things that he did like to eat is ridiculous!!
-So that is my story. Good luck on your son!!! -- By the way, how can I find out more about this National Milk Bank? I am due to give birth in a few weeks and am curious about donating my milk!

Hi,

Do you know if blood allergy tests can be false negative? Anyway I just wanted to say I cant help much with your questions, but with the asthma, often times is really just an allergic reaction. He may be reacting to those things after all and that is how it is coming out.

my son is 3 year old I had him tested my both skin and blood I wanted to make sure. He is allergic to Peanuts and shellfish. his numbers came back very high. He onece had a chex mix it did not have peanuts in it but it was made with peanut flour, and never had a reaction.Once I found out about the testing I will not give him that anymore. The Dr. said it could of been the amount of protein from the peanut flour that is why he did not have any reaction.

The thing that upset me the most when I took him to the allergist was he asked if my son ever ate peanuts or shellfish I replied NO, then he asked if I breastfeed and said that is probably how he got this allergy through my milk. ( I did have peanut butter and shellfish is one of my favorite foods)

I called the ped. crying that I did this to my son and he told me not to listen, but could it be true could he have gotten this through my breast milk. If I knew I would of never ate any of that,

i AM GOING THROUGH THE SAME SITUATION. MY SON WHO IS A LITTLE OVER 3 YRS. OLD WAS TESTED FOR ALLERGIES TO FOOD. IT CAME BACK THAT HE WAS ALLERGIC TO MILK AND EGG WHITES. IT TURNED MY WORLD UPSIDE DOWN BECAUSE ALL HE EATS ARE MILK AND AGG BASED PRODUCTS. I AM TAKING HIM TO AN ALLERGIST BUT HE DOESN'T SEEM TO BE SECOND GUESSINGIT. ANYWAY NOW MY SON DOESN'T EAT ANYTHING SO I AM TAKING HIM TO A NUTRITIONIST TO GET HER OPINION THEN I WILL TAKE HIM TO ANOTHER DOCTOR FOR A SECOND OPINION. I DON'T KNOW WHAT ELSE TO DO BECAUSE HE IS LOOSING WEIGHT ALSO.

A few of my friends have kids with allergies to all the things you mentioned. I think your son would have some sort of a reaction to the allergens if he is in fact allergic to them. I'd say get him tested again, now. It doesn't seem right that he is supposedly allergic to all those things but has no problem with them. Why wait until the summer to find out? He's old enough now to be tested. If one allergist says no to testing him now, try another. Kids often outgrow allergies, I'll keep my fingers crossed that that's the case for your son!
