Bryson (3/06), former Neocate, Nexium, and Reglan baby. Diagnosed with peanut allergy and asthma. Weaned from meds in Spring 0f 08. Brother, Parker (6/04), was also on Prevacid and Pregestimil (formula) as an infant.
RAST test results (peanut)
I have been gone for awhile since I am now back to teaching and get very little time to search the internet. My son was diagnosed over a year ago with a peanut allergy after having a scratch test completed. He tested 4++ on the scratch however the follow up RAST test came back as .70. Completely different ends of the charts so I have no idea how severe or not severe the peanut allergy could be. My question is that we just had the test completed last week and it has gone up to 6.8. Our pedi said that was a significant jump. I have not spoken to the allergist yet. I know that the test is scored out of 100 so I am not sure if a score of 6.8 is bad or not. Does anyone else know? He has never ingested peanuts as he still eats Stage 3 baby food at 2.5 years of age. Not by our doing, but by his choice. So, I was surprised that it went up this year. Can anyone explain why a score would go up? Like I said we have not spoken to the allergist,but our pedi said it was a big jump and we needed our Epi-pen refilled. Thanks for reading. amanda

Bryson (3/06), former Neocate, Nexium, and Reglan baby. Diagnosed with peanut allergy and asthma. Weaned from meds in Spring 0f 08. Brother, Parker (6/04), was also on Prevacid and Pregestimil (formula) as an infant.
It just dawned on me and I can't remember if he had any antihistamines within 3 days of the RAST test. He went to see the pedi for his ear because it had been draining for 2 days. I can't remember if I had given him any Benadryl withing days of that visit. They drew his blood on this visit. I do not think I did because his eczema has not been bad. He is on Allegra and I am not sure if that is considered an antihistamine that would effect the results of the RAST. Now, I am wondering if he is not sensitive to Amoxicillin because as of today he started breaking out on his belly and tugging at his groin area. Just went to check on him at naptime because he was crying and his belly is broken out in little hives. I gave him some Benadryl. He is on the 9th day of meds, so it is hard to believe it would be the amoxicillin. That is all he has had different. Oh, and a little tiny bite of ham from brother's lunchable yesterday. He didn't like it and I'm not surprised! I am thinking his lunchbox in Kindergarten will consist of one Gerber fruit, meat , and vegetable. Ha!

Donnessa, mom to Halley born 3/10/07
Reflux (mostly) resolved at 14 months
and Addison born 8/17/09. Currently exclusively bf and on 7.5mg Prevacid
Well, at least my child won't be the only one with pureed foods in their lunch box - it's the only way I can get mine to eat vegetables. That's weird about the rash - I'd give the pedi a call. I agree that I would have expected it to show up earlier if it was a penicillin allergy.

Maggie is now 3 years old and reflux free (knock on wood). I still check in some to see how everybody is doing :) Hugs to all!
I'm trying to remember how long it took for Maggie's penicillan hives to show up. If I'm not mistaken, she had been on it for a few days before she broke out. Let me ask dh.

I'm sorry I know nothing about pnut allergies.

Pictured: G'mom w/3 kids. I'm mom to 1 angel Melissa (dec'd 11/92 - hypoplastic left-heart syn.)
2 healthy daughters (knock wood) Cory (16), Kim (11) & Eric (4) diagnosed with e.e. (scoped 8/08), GERD & severe food/seasonal allergies, asthma. Cried non-stop first 17 mths. of life Found out he is allergic to cow's milk, soy, eggs, and peanuts. Takes Prevacid, Neocate One Plus & Flovent.
Hi again! It's been awhile. My son is also 2.5 & eating baby food. It's because he's allergic to nearly everything and he is used to it. We just found out he has e.e., as well, so everything is about to change (we will be dealing with allergist at Children's Hosp. in Phila.) Anyway, Eric has only had scratch testing & was found to be allergic to peanuts, soy, egg, & dairy. But, he is about to get the RAST & patch-testing (to check for delayed food reactions). I am not sure about the numbers yet, but I am pretty sure you need to avoid all Zyrtec, Benedryl, etc. 3 days prior. No matter what, I would get the Epi refilled and just be prepared. Does he have asthma? My son developed seasonal allergies & asthma also. It's horrible. I would watch that antibiotic. Sounds like it could be an allergy & yes, he could be reacting on day 9. Have you called the Dr.? Let us know how he's doing. Ellen

Melissa - Mommy to Sebastian, born 9/28/07 @ 7 lbs 7 oz and 20.75 in. At docs at 12 months: 27 pounds and 32 in! Good grief! GERD - currently on Prevacid suspension (liquid equivalent of 45 mg a day). Allergic to dairy, soy, eggs, wheat, all treenuts, peanuts, fish, shellfish, peas, sesame, bananas, barley, coconut, dust, dust mite, dog, cat, latex. Seasonal allergies. Oral Allergy Syndrome (OAS). Neocate only - no solids - until further notice (drinks and loves water, too). Loves his doggie, our rescued Treeing Walker Coonhound, Louise, even though he is allergic to her. Louise will make your doctor a homemade pie if you would like her to. PHOTO: We couldn't do a cake on Sebastian's birthday, but that didn't stop him from tossing around the contents of a big bowl of popcorn! He now tries to eat it when we play with popcorn, so no more of that game.... :(
Hi there. I think I can help. Any antihistimines (Benadryl, Zyrtec, etc) have to be avoided at least 3 days (preferably longer) before any type of allergy testing because they skew results. But I don't know what Allergra is considered. I think it is an antihistimine because my son cannot have it except in absolutely emergency situations because he reacts adversely to antihistimines. I believe it falls in that category, but I could very well be sorry.

The problem with a peanut allergy is that the numbers really don't matter. You can have a very high number (my six-year-old niece is 66) and react with hives, and you can have a low number and go into shock. You just don't know, so my advice is to absolutely avoid peanuts at all, all, ALL COSTS. We get our informatiom from our allergist (Dr. Wood at Hopkins, the leading pediatric allergist in the country) who actually also has a peanut allergy.

My son has never been exposed to peanuts to my knowledge (I didn't even eat peanuts when I was pregnant, but I did eat food processed on shared equipment), but he tested at 5.7 for peanuts ta five months of age. That is a pretty significant number for a young child. Your son's is high, too.

Hives usually show up on the belly first when an allergenic food is eaten. How is he now?

Thanks for the info. I gave him Benadryl yesterday and when he woke up from his nap the rash and small hives were gone. Just a few little spots in his groin area. I gave him another dose last night and he never broke out again. We are now finished with the meds so who knows if it was the medication or something else. To answer blueleopards question, my son does have asthma but mostly only has problems when he becomes sick. He does take Pulmicort daily. We have avoided peanuts since we got the first test in July of 07. I need to find out about peanut oil and if it needs to be avoided. I have heard conflicting information about peanut oil. I have heard that most individuals with a peanut allergy can tolerate peanut oil. I am not ready to take that chance! We did get his Epi-pen filled and we are ready. I pray we never have to use the thing. Thanks again.
Check with your
doctor first!
