Obviously, with something so incredibly useful, we want it to be used in a manner that both is efficient and makes the most sense. Attempting to ensure newborns don't die early or suffer from one of these diseases is important. This is why it is crucial for this screening to be used (which may take about ten years to be implemented fully in the U.S.) once an effective approach is figured out by researchers. Another factor of importance is making people aware of this which may make it easier for them that just because it's new, doesn't mean they have to fear it. It may take time to perfect the use of this manner of screening, but it will eventually help millions of people.
