I know only minimal information on the UKnow test. I think it can cost up to $300, out of pocket, no insurance covers it. I learned at the FAAN conference this year, for peanuts, scientists have identified 3 epitopes: Ara h1, Ara h2, Ara h3. Ara h2 is the one that people are more likely to have long lasting peanut allergy. I THINK according to the UKnow test, they will look at all the epitopes (not sure if I'm using this term correctly) and determine if your child is on the lower or higher spectrum of being allergic.
OK according to the Uknow chart, they will tell you if your child is at risk for a severe reaction by isolating the antibodies (epitopes??) in your child and see if your child carries the one that is known to cause severe reactions.

I'm concerned about it in the sense that how do we know if our child will go from not having the marker for severe reaction to actually getting it. There is no way of preventing it so what good is a test to know whether your child has the marker or not if there's a possibility of having the severe one?
