Interesting. I wonder how many how many other issues we could screen for using such simple, low cost tools. Some scales can already detect reduced blood flow in the feet (which can be a sign of all sorts of nastiness).
A shorter amount of expensive time with a consultant is more powerful if there is a solid reference to play with for longer before hand.
For instance, even WebMD might waste more time in doctor's offices than it saves, and that's a true, hallucination-free source, written specifically to provide lay-people with understandable information.
