Are certain tree nuts more likely to be related to peanuts than others?

My DD's allergist is doing a repeat RAST test and will be checking for tree nut allergies (previously only tested for eggs/peanuts) When I got home I noticed he only checked off walnut and almonds. I can't find any info on why he would have chosen these two specifically. She's never had any tree nuts, so there is no history of reaction.

Are those two nuts related more than the other nuts??

Tree nuts are not related to peanuts in anyway.
Peanuts are a legume - part of the bean family.
According to my trusty little worn out Webster's Dictionary "any of a large family of plants having fruits that are dry pods and split when ripe and including important food and forage plants as beans and clover".
Why your child's doctor chose to only test two tree nuts I don't know. Perhaps a conservative approach??? Perhaps one as a tree nut and one as a "fruit clasified as a treenut".
Some will tell you an almond is actually a drupe which means (OK here goes my little Webster again!) "a partly fleshy one seeded fruit as a plum or cherry that remains closed at maturity".
My DD tested positive to all of the tree nuts and almonds and coconut(also now considered a treenut).
I would ask the doctor why.
Good luck!

coconut is now considered a tree nut?? I know shea nut is, but I thought Coconut is okay .... We avoid tree nuts due to PA, but have been eating coconut all along...

Yes coconut is now classified as a tree nut and if you have any time to search, there are two or three threads in this forum about it. (if I remember correctly the first thread about this was back in the late fall of 06)
Some people are very unhappy about this classification - we are grateful. When I used to call manufacturers they would question why I was asking about coconut as it is not one of the top 8! OK Duh@!
It is not unusual that your child is not allergic to all tree nuts.

Our doctor checked PA dd for almonds, pecans, walnuts, and cashews. He said those are the most common nuts used in cooking, etc. I would have liked to know ALL the nuts, but insurance wouldn't cover it, and it would have meant that much more blood from dd.
The doctor we use is a peds allergist, who was working on the ?Tanox vaccine (the one that got put out of business), so I'm trusting him to have some idea about the utility of the test.

An excerpt from this article is:
"This new edition is extremely helpful for members because it eliminates all uncertainty about which tree nuts should be identified as allergens on product labels," said Michelle Matto, IDFA assistant director of regulatory affairs. "We appreciate the FDA's efforts to clarify labeling issues as questions arise and new information becomes available."
The latest edition of "Questions and Answers Regarding Food Allergens" specifically identifies these tree nuts: almond, beech nut, brazil nut, butternut, cashew, chestnut, chinquapin, coconut, filbert/hazelnut, ginko nut, hickory nut, lichee nut, macadamia nut, pecan, pine nut, pili nut, pistachio, shea nut and walnut.

we were just at our annual allergist appt today. yes, coconut is a tree nut, and has been considered that for some time.. walnuts are the tree nut that "most" with tree nut tend to be allergic to. However, not in my son's case. He isn't allergic to walnuts, but off the charts for cashew. hope this helps

Interesting. My DDs are allergic to peanuts and the skin test showed them to be allergic to many tree nuts (esp. walnuts), but they eat coconut all the time and are fine with it. I hadn't kept them away from coconut because I didn't think it was botanically an actual nut.
I've heard conflicting information about shea nuts and shea butter. I need to know for sure about shea butter because it's in a lot of lotions nowadays and my girls are older and buy/use lotions by themselves. I'm not sure whether to tell them that shea butter is off limits.

linking...see my post at the end
Also - "shea" is a drupe, and depending on the product we either use the seed part (nut) or the endocarp (flesh)

Now I'm more confused! LOL Even after looking at which ones are seeds versus true nuts, etc, it makes less sense to me! I guess I'll have to call him and hope they let me ask. It's really more about curiousity than anything, just thought it was odd that he only checked one and had to specifically write in another, so it's not like he just accidentally missed checking one off.
I suppose it truly doesn't matter, as we'll avoid all 'tree nuts' but it would have given me more peace of mind knowing the results on all of them. (I did resist temptation and didn't check them off myself!! haha)
Thanks for the feedback!
