Mr. Tony O'Brien:

They referenced about a 1.8 return rate of high grade, which they normally experienced, versus a 1.2 return rate from the 1,000 slides. That is their data and I have no reason to question it. Currently, the return rate of high grade is at 1.66. A number of things were different. We have discussed the double reading and the fact that the laboratories in question know they are dealing with a population in Ireland that is screened on a three-year cycle. They have dedicated cohorts of readers who are screening Irish-originated slides. None of that was the case with those 1,000 slides.
