@Adira: I know nothing about these tests, but I'm pretty sure coconut is considered a fruit.

This is on our lab results -

REFERENCE INTERVAL: Allergen Interpretation
Class 00: Less than 0.35 kU/L Absent or Undetectable
Class 01: 0.35 - 0.70 kU/L Low
Class 02: 0.71 - 3.50 kU/L Moderate
Class 03: 3.51 - 17.50 kU/L High
Class 04: 17.51 - 50.00 kU/L Very High
Class 05: 50.01 - 100.00 kU/L Very High
Class 06: greater than 100.00 kU/L Very High

Results with allergens scoring in Class 1 should be considered weakly positive or equivocal. Class 2 or higher should be considered positive. Although increasing class ranges (01-06) are reflective of increasing concentration of allergen specific IgE, this may not correlate with the degree of clinical response when challenged with this specific allergen. The correlation of allergy laboratory results with clinical history is essential.

@Adira: Yea I'm sure they will give you a detailed write up! Almost all nuts are processed in a plant where the other nuts he is allergic to would also be processed so you probably still have to avoid them all unfortunately!

ETA - posted at the exact same time as you

Based on those results our allergist would say the <.35 are negative and let us food challenge all of the others except peanut! Food challenge is the gold standard since bloodwork can give information but not an exact diagnosis. Sooo like my son has scores between 1 & 2 for almond and sunflower seed but he passed food challenges to them in the office and can eat them! And cross contamination does rule things out sometimes but occasionally there are things that he can have based on knowing each specific nut (like Barney butter almond butter which is peanut free!). Definitely speak to your allergist about the results.

And to make you feel better about the peanut value, our most recent one is > 100

Is his eczema getting any better (re: previous thread)?

@adira we're getting our blood test results tomorrow so i will try to remember to come back and post.

In regards to all the food challenge mentions, how young will your allergist allow children to do food challenges? LO (7m) has green mucusy diapers when exposed to peanuts / hazelnuts via my breastmilk, but DH's allergist seems unconcerned and won't test until 2. Both DH and BIL have peanut & tree nut allergies.

@DesertDreams88: our allergist skin and blood tested our LO2 at 6 months. Her results were that she had no allergies so we were instructed to immediately begin feeding all of the "allergy" foods and she has not reacted to peanuts or any of my son's allergy foods. She did react to egg at around 8 months old and was offered a food challenge at 9 months old. We decided that for that one we would wait because the allergist said it wouldn't hurt anything and a food challenge can take 4-5 hours. That would be a very stressful appointment for her based on her current nap needs. All of this said, if I was in your shoes I might consider seeking a pediatric allergist willing to do testing at a young age. It could give you more information and help you be prepared if an allergy does exist (or give you the go ahead to feed all of the foods!) hope that makes sense. All in all I am a huge believer in having a great allergist in your corner to give you good options and information on your specific situation.

@Adira: she failed the food challenge at age 7 and is about to turn 8. She will be embarking on OIT (oral immunotherapy) this fall for peanuts and I am cautiously optimistic. I hope for your LO that many of those numbers are just false positives. There was a study recently that said younger siblings have a very high rate of false positives (such as in the case of my DS who has the very low numbers but does not react. He is almost 5)

@T-Mom: don't mean to thread jack, but quick question about OIT that I've been wondering about. Was she offered the therapy because her numbers were low enough for the food challenge? Best of luck with the therapy!!

@T-Mom: thanks, will wall you at a later date to find out how it's all going! I know our allergist doesn't do it so we would have to go the private route, too.

@Adira: that sucks, I'm sorry

@Adira: definitely, I would too. It really depends on the allergist. My DD's very first allergist said for us to come back in a few years (she was 2 at the time, and they said maybe like at age 6). I was not ok with that. We got a new allergist who tests yearly after that and who was more forward thinking and involved in research. You have to do what makes you comfortable.
