This becomes one way we're hoping that we can identify patients who might have severe problems and can be warned about it.

It's still a hard core piece of work for us to get the message out to people as to how to protect themselves. It obviously would be nice if we could identify which people are more at risk and this particular study is . . . an opening into that field.
