Yes it can be. Research the T-21 test, its a simple blood
draw vs. a panel of blood tests they did to determined a risk of down syndrome. I know a preggo mom, they told her the same thing, and when I told her about the new T-21 test, she had her doctor order that day. She went in, had her blood drawn, and got her negative results the next day. She was Thankful because she didn't want to risk going through the amnio if she didn't have to.
