Interesting observations:
US approval five to seven years of foreign testing.
Longest European delay: Germany six months. Germany re-ran all our test themselves.
Shortest approval: UK. One month, accepted our test reports as gospel. Delay for paper processing.
IIRC France re-ran some tests but not all. Even Italy did some tests.

The blood testing machine sold for about one million dollars but the real money was in the reagent, $10K per liter. Management continually urged us to speed up the tests so the machine would use reagent faster.
Only USA & Europe paid full price for the machine. Maybe Japan. I don't recall us marketing there. Third world got it either greatly reduced or free. Still had to buy the reagent.
