Mr. Damien McCallion:

The historical context is one of the things at which Dr. Scally is looking. His report will identify where that happened. On quality assurance, a range of measures make up the quality assurance in respect of laboratories. It included site visits. The frequency of these was once every three to four years. With the appointment of a new pathology quality assurance lead, we will move to annual reviews. He has been asked to make ensuring annual reviews one of his priorities. That will be one part of overall quality assurance. Part of it is the monitoring of figures, including positive predictive values, PPVs; negative predictive values, NPVs; and various other indicators relating to laboratories.
