Sorry about no one answering your posting from Nov. But I was looking at some of my questions and response and I found that yours had never been answered. The answer to your inquiry is that you can type in the words down syndrome testing onto google or sbc yahoo seatch engines and you will have all of the data that you ever wanted to vuiew. There is plenty of information on that topic. All of the best in the search for your answer. I just wish that someone would have answered your inquiry long before this.
