I'm trying to think of what bad news there might be. Does anyone seriously doubt their ability to develop these tests successfully? Would they be setting up a worldwide sales infrastructure if there were any doubts? We already know that their developmental Down syndrome test compares favorably with what is currently used. And Stylli pointed out in the conference call that the increased r&d involved not only pre-natal, but other diagnostics as well. This is a growth story in a very hot field.
