This is a pretty cool idea, with a technique that is both simple and proven. It's a mechanical test so they're basically coming up with an efficient way to do ancient medicine. Warfarin is almost free, but your diet and health changes can impact it's clotting impact, and changing your dose is like steering a cruise ship: long lags between inputs and final results. I've had to use a fast-acting injectable while getting into my clotting range which can take almost a week at $100 per daily shot. This also involved going to a clinic daily, then waiting for my doctor to get the results and phone me up, just to change my warfarin dose. You then go happily on your way but need to test regularly to stay in the desired range.
The quality of life impact for millions of people could be enormous. Kudos!
