So, by that theory is his thought not to introduce nuts into the diet till the age of 4 as opposed to the recommended age of 3 now?
Since introducing is a form of testing....

We got the CAPRAST results back on our 11 1/2 month old DS - no known allergies, just some eczema (we have an almost 3 yr. old PA DS). Our 11 1/2 month old tested negative for milk, soy, egg and peanut...thank God. According to our allergist (at A.I. DuPont Hosp. for Children), if he was exposed in utero or while breastfeeding, he would show the antibodies in his blood. I'm going to start dairy for him, then egg, but hold off on any peanuts until he's 4. From research that I've done, the CAPRAST is supposed to be very accurate for these 4 allergens. As of now, my 3 yr. old PA DS has tested negative for almonds, pecans, sesame and coconut. Our allergist does not want to do any food challenges until he is 4. He said we'll do another CAPRAST (one when he turns 3, and another at 4), and if it turns up negative for the tree nuts again, we'll do a skin test to see if it's negative. If both the CAPRAST & skin test are neg., then we'll do the food challenge. I like this allergist b/c he's not crazy with the skin testing - I don't want to expose him to any type of nut! He also told me not to give him coconut or sesame until he turns 4 b/c the proteins are so similar to the peanut protein. I thought that was pretty intriguing & something you might find of interest.

We had our now 17 mo old tested at 9 months. Her older sibling was positive at the same age tested positive for egg, dairy and peanut. All of which were at anaphylatic levels.

Can I ask what that means? Is there such a level, or did you just mean her older sib was rast at >100? Because Caitlin's rast for egg/milk are >100, but when BF, the only reaction thru BM was eczema flares, no anaph. We've been egg/milk free now for 2 yrs, and never had anaph. I dont consider her anaph to either, just highly allergic. I dont know WHAT her reactions would be if she had a glass of milk (or a cookie with milk)

Sounds like most are doing RAST on young siblings. Anyone done a scratch on a young child? (About 1 yr old) and why or why not?

My 1 yr old had his 1st allergist appt today and I asked about the accuracy of allergy tests when theoretically there's been no exposure. He said you CANNOT test positive for a substance you have never been exposed to. He said very frequently though he has people test positive who's parents swear there's been ABSOLUTELY NO exposure, even prenatally or through breastfeeding. However, they must at some point have been unknowingly exposed. When you consider all the cross-contamination issues, I suppose this is the most likely scenario. My 3yr old had a reaction to residue on the counter at McDonalds...even if you are not eating peanuts, it's impossible to avoid so I suppose if you are pre-disposed to be very allergic to peanuts, it might take very little to sensitize you???

We got the results back on my almonst 1 yr old son. We did a CAP RAST for peanut, egg, milk, and soy. All came back negative, so the allergist said we could introduce dairy & egg (which he's had none of, except in exposure through BM). My almost 3 yr old is PA, and we are avoiding all TN. I was really glad everything for my youngest came back negative, and so happy I would finally be able to feed him something besides plain, unsalted rice cakes :-) BUT, We tried a few tablespoons of yogurt, and he got 2 little hives around his mouth; same thing the next day. I didn't give him any benadryl b/c the hives didn't change, and they went away in about 30 min. I thought maybe there was an additive in the yogurt that was bothering him, so I tried a slice of American cheese on the 3rd day. 2 days in a row, same thing, a few hives around his mouth. The 2nd time we tried the cheese though, I let him feed himself, and this time he got 8-10 hives. So we stopped there. The hives were NOTHING in comparison to what I went through with my oldest the first time he had a tiny taste of PB, and he had an anal. reaction.
I called the allergist, and they said not to give him any dairy, and to bring him in for a skin test...which I can't get an appointment for him until 10/23. They told me the CAPRAST was 85% accurate, and should be followed by a skin test if negative. If I had been told that the first time we were there, I would've had a skin test done to double check the egg & dairy before giving him dairy. So now I'm trying to take the crash course on dairy allergies, and make a dairy-free, P/TN-free and safe birthday cake for his 1st b/day tomorrow. UGH. If we end up with one PA son and one Dairy allergic son, I guess we'll all be eating a lot of salad.
Any experience you've had with possible dairy allergies, I'd appreciate any kind of feedback. This site had been an invaluable source to our family. I admire all of you for being so strong.

Deanne...you didn't say what the test results for your 17 mo were. We, too had our younger son tested at 9 mo (he is now 15 mo). At that time, he was being tested for milk so I thought, if they're going to puncure his vein anyway, why not just test for peanuts and tree nuts. Everything was negative. The allergist has told us to be aware that he could test positive any time in the future, though. I guess we'll re-test him around 3 or 4 yo. His older brother, age 4 1/2 is the one with the PA/TNA.
