Hi, I'm not a doctor but based on my experiences, I would not advise it in such a young dd. We had it on our DS when 14 months, it can be very misleading in such young kids, it may show up high IGE levels to allergens that your DD can tolerate - depends on how severve the overall IGE levels in the bllod are.

Sorry - not very clear, but I wish we had not had ours done on DS.

my ds had it done at 15months and was inconclusive which was disappointing

I am not sure how much help I will be. My ds had his RAST test done towards the end of January at 19 months. I had a call last week to say the results are in and there are some positives (which I was expecting), but we don't get the results until wednesday.

From what I have heard and read, it is extreamly unreliable in the under 1's and not always reliable in the under 2's.

I worked out 2 allergen's for my ds just by keeping a food diary and monitoring reactions. Having said that, his gets pretty obvious skin reactions, hives, which are hard to miss!

Ds was tested at 2 for latex and has a moderate allergy. Skin prick showed nothing.

i would try skin prick first.
