Food allergy testing?  

post #1 of 11
Thread Starter 
I took my dd to the allergist Thursday about her allergies. She is allergic to milk, strawberries, kiwi, and some antibiotics.

For some background info-since she was born she had this bad rash, mostly on her behind. It was unlike daiper rash, and was more like hives and welts. She was also horribly colicky, and had nasty strange poops. I did the elimination diet and found that within a week (I bf her) she was better. The rash went away, she actually slept, had normal poops. And if I did get some dairy in me, she would generally have a minor rxn (I never got much in me) within 1-3 days.

But as she has gotten older, it has gotten more severe and more sensitive to the amounts I might get. She has never actually eaten any dairy so far as I know. But things have gotten to the point where she has this happen almost every week now. Her rash starts like where diaper rash would, spreads out to her upper thighs, lower back, lower stomach, and butt. It has always been like this, or spread farther depending on the amount. Sometimes they bleed and turn into huge welts that scare the daylights out of me-and I've seen a lot being in healthcare for 6 years. I give her Benadryl if it gets too bad and they go away much quicker than if not.

And it happens like this now if I even eat a cracker with some whey in it. I can't imagine what will happen if she ate a piece of cheese. I am very careful, but you never know with cross contamination or is she finds a crumb on the floor from dh.

Well, the doc was nice and seemed very knowledgeable, but he wasn't very helpful. Firstly, there was another 1.5 yo girl next door to our room and he kept getting us mixed up as he went back and forth. He kept talking about her eczema and asthma. I was :

They did the skin scratch test for general allergies like dust and pets, etc. and also tested for strawberries, milk, and casein the nurse said. But they made her bleed on the milk and casein one! I thought they weren't supposed to make you bleed! All of her tests showed negative results, as they were nonreactive. He said that those tests aren't very reliable with young children, and she would probably have better results if she were around 5 or so. But within the time it took to leave the office she said that her butt hurt and now today she is beyond in pain and won't even sit down. She is running around naked right now because anything on her and she screams.

Could the milk stuff they put on her to test her have gotten into her blood and caused this? I am so sick of dealing with doctors. I'm not expecting medical advice, but is anyone else going through this?

Yes, some allergists don't do SPT because they are an exposure to possible allergens. RAST testing can be done w/o exposure. Did you get a prescription for Epi Pen Jr's?

No, because she is not anaphalactic. And we went to a new doc today. We are going to try her on some clarinex, acidophilus, cut out gluten and yeast, and some topical nystatin stuff for the yeastiness that has been about lately. And if it doesn't work in a couple of weeks, we are going to do blood testing...

I honestly think that a combination of allergy testing and an elimination diet is your best bet for figuring out her allergens.
Probiotics and cutting out grains and yeast are good starts...incidently, if she's having a yeast problem, cutting out sugar is a good idea too. Yeast loves sugar!
We did blood and skin tests at around 10 months and they were accurate for us but that's not always the case. We tested for things we were suspicious of and eliminated everything she was + for and her symptoms (eczema mainly) were gone within a few weeks. She got minor hives daily for another 6 months but those have become much less frequent in the last three months (she is 21 months now)
It could be that her symptoms are not caused by an allergy but by an intolerance although hives is generally an allergic reaction.

How old is your daughter? Lots of people become more sensitive with repeated exposures to allergens. That could be happening if you inadvertantly eat things containing milk or she finds something to eat or is around other kids much. And if she bled on the skin test then the proteins could have gotton into her bloodstream and caused a reaction. We've had good luck treating reactions with Zyrtec...that might be one to ask your doctor about. It accumulates in the skin, so it works well for eczema outbreaks, it might kick youd dd'd rash in the butt (so to speak!).

I went to a new doctor on Monday. He was great. HE says that she is definitely allergic to milk, no matter what the scratch test says. He says he doesn't trust them a bit because they are so inaccurate. He was quite relieved that I was bf, and says to make sure we check labels (we already do). He thinks that she has just been exposed so many times to milk, that it is becoming worse and worse and that it has messed up her digestive system so bad that the yeast is attacking her and that it's causing the yeast rash. So she is now on acidophilus, clarinex, and nystatin combo cream. And we are avoiding yeast, gluten, and sugar as much as we can (we aren't perfect). I forgot to mention the dietary changes to him, but I am sure that it will only help with the yeast die off.

I guess I got lucky that my doc is lactose intolerant and has read enough into it himself that he doesn't think that I'm cukoo for even considering food allergies.

You may want to ask about hydroxozine too. It is suspected to be curative for some allergies. It hasn't been proven, but our allergist really thinks it helps to actually cure/reduce strenght of children's allergies.

And yes, scratch tests only catch a portion of allergies with specific reactions. The blood test will catch others, and some they have no tests for yet. Allergies are incredibly complicated and Dr's are just starting to really figure them out.

I'd be reluctant to try hydroxyzine. It is a sedating antihistamine, non-sedating benzodiazepine. It can cause sleepiness and my allergist suggested not using it because Claire was less than 1 yrs old.

She was diagnosed with ImmunoCap blood testing.

I gotta do the Rast Test...can a regular Ped draw the blood and order hte test??
post #10 of 11
Hey 'Bama: any ped can draw the blood work.

There are a number of different panels so make sure you ask what exactly is going to be tested for.

Claire got a comprehensive food panel as well as a nut panel and grass inhalent. We weren't worried about molds or pets at this point.
