Oh this is awesome. I always wished there would be something like this along the lines of blood tests. Keep an anonymous public database of blood tests results with known diagnosis of the patient, age, ethnicity, global region, etc and publish it out. Can be completely anonymous and people would basically just get an immutable entry every time they have a blood test over their lifetime with whatever the dataset happened to be that day.<p>Would be an excellent way to mine for commonalities among different conditions. I just assumed there was already something like that, but private. Seems like it would enable fairly significant study.
