RAST Test Results
A friend of mine just had her son RAST tested for PA after he had a mild reaction to a peanut butter and jelly sandwich(hives around mouth). He is three had had small amounts of peanut before with no reaction. She wanted the CAP-RAST, but unfortunately got a regular RAST. The level was 1.78ku/l.
I am personally leary of any test but perhaps the CAP-RAST because my daughter had so many false positives. Does this level suggest a positive result, or is it more of a "maybe/maybe not result"? Does anyone here have levels this low with a child who reacts? Any links you can give me that would tell what this level actually means (ie, % of kids who will react at this level).
