Arguing about capacity Vs performed is missing the point. If there's unused capacity, why is it unused?
Are they maintaining a level of testing in case there's a surge in front line staff who need time day? Or to prevent a backlog of tests building up? Or because all those tests can only be accessed in one area which doesn't need them all.
Northern Ireland has three test centres for about a million people. Wales has one for about 3 million people.
Or are there other reasons that mean that the tests can't all be taken up? Should they be taken up? Should we have capacity for more than 100,000 to allow 100,000 to be performed each day?
