HEllo Everyone. Well, Zakary had his sweat test done this morning. They said that by evening we would possible know the results. But when the test was over and they were removing the patch of sweat she stated that she felt we were going to have to go to advanced testing because there wasn't enough there. She stated that some children just dont respond well to the test. I was just wondering if this happen to any one else? What is the "Advanced testing"? and does this mean something that he was unable to complete the test the way the hoped? Any thoughts are much appriciated. I just and going crazy now knowing all these anwsers.
