A lot of this research is very involved and esoteric, requiring specialized equipment found only in one place, so some would be very hard to replicate. If what Theranos was doing (or claiming to do) was easy to replicate, it would've imploded years prior to when it did. So not all fraud could be detected, but a lot of the low-hanging fraud, especially in the psychological and pharmacological fields, could be quickly identified. Such a system would be a substantial upgrade and I applaud your suggestion. A smaller country could blaze the trail, because "big boys", like the U.S., are too set in their ways.
