Given the size of hospitals around the world, I'd assume its not unlikely that they'll buy 100+ of these devices. I agee that this is somewhat confusing, but it doesn't seem too unrealistic. Also, it seems like the actual test is the cartridge which is inserted into an existing device. So the device is probably already in use in some places and can get this extra test capability by just inserting the cartridge.
