Thanks for the answer. I would like to specify still - whether that all the last 3 assays could affect or influence result of assay, similar put to the child in one handle (at least last 2 times precisely), did not alternate or interleave a forearm. And disappearance or eradication of red maculae completely for a week is not the proof of what reaction allergic? Thanks.
