Max was diagnosed as a result of newborn screening, but we didn't get the official diagnosis until about 2 months later when the ambry results came back. When we were first contacted, I was a little hopeful that the high numbers just meant that he was a carrier since my husband had been told that he wasn't a carrier (we knew that I was). Well ... little did I know that he had only been tested for the 4 most common mutations (not that I knew that there was even more than 1). I can't tell you how many times I licked him (and then my 3 year old to compare) during the agonizing wait - each time realizing that he tasted quite salty!
