Just to mention really quickly about testing--because you've heard me before talk about it, and then it was a little bit misquoted and misaligned--but there are multiple Abbott machines, so I'm going to be very clear, having spent years in the laboratory. The high-throughput machines, which are the Roche 6800 and the 88--I think it's the 8800 on Roche--and the Abbott M2000--these are the machines that run between 500 and 1,000 assays at a time.
