My ds’s GI said that the Endoscopy Biopsy showed now sign of allergy…

How accurate is this test for allergies?

It’s been a year since ds’s last RAST and skin prick. I was thinking of doing it again. Should I trust what the GI says or will the RAST and skin prick show more???

TIA!!

it would show if he had any eosinophils, which are “allergic” cells. i would say that it means that he does not have any allergies that are causing any kind of esophagitis. i’m guessing it wouldn’t tell you anything about hayfever-type allergies since they usually do not affect the esophagitis—as far as i know. sounds like food allergies don’t have anything to do with his reflux.

Interesting…Thanks so much!!

Do you think that means I can give him milk and soy now?

Just out of curiousity myself…

When taking biopsies & looking for eosinophils…isn’t it similar to looking for celiac. Hit or Miss? KWIM? Don’t they have to get the “right” spot?

Also, like Laura mentioned…There’s always intolerances too.

Depending on the above(whether or not the “right” spot is needed for accurate diagnosis)…I would do another SKIN PRICK allergy test. RAST isn’t very reliable & your LO was only about a year(?) when he was skin pricked for allergies? The most accurate time frame for allergy testing(skin) is b/t 18mths-3yo. Something to consider?!

Okay, I like what you are saying. I don’t know about it being the right spot. But, I like the idea of doing a skin prick rather than a RAST. He was a year before and now he’s two.

I’m going to make an appointment tomorrow for the skin prick. I hope they can get him in ASAP. Last time it was a 3 month wait.

Thanks for the info. You all are soooo wonderful

amber, i don’t think looking for eosinophils is the same as looking for celiac as far as hit or miss. i could be wrong, but the reason i say this is because when kassie had her scope and biopsies, (and we didn’t suspect celica at the time) our ped gi came out and showed me the pictures from the scope. you could see white spots all the way down her esophagus—even without having to look at it microscopically. the doctor told me that it was either food allergies or thrush. so, i am assuming that food allergies are more visible to the naked eye, but also resemble the spots that a fungus infection makes. he said they would not be able to tell without looking at it microscopically, but the lesions were defininitely obvious to the naked eye. they turned out to be thrush—–and they didn’t pick up that she had celiac disease. of course, they biopsy in a different place for that and they weren’t looking for it.

i think i’d have the skin prick done again, too. we have had sammie skin prick tested and it showed nothing—but looking in her nose and throat, the allergist says that he sees allergies. the plan was to wait a little longer and then do the sub-cutaneous needle tests. i think i should have gone back in by now, but i know she will just die when she finds out what they will be doing to her. when they had her breath into the tube—-she showed almost borderline asthma, though she has never had any asthma problems. i did just read in my journal, though, that as a baby she had raspy lungs once. she often wakes with puffy and red eyelids.

can allergies affect their behavior, she is hell on wheels, adorable, but she gives me a run for my money.
