We have also introduced new tests, new types of test, so for example at least two NHS labs are now using a test that has no RNA extraction stage, which means no need for the chemical reagents which are in such high demand around the world.

In addition, we have the three new lighthouse labs which are all now on stream - these are the ones in Milton Keynes, in Manchester and in Glasgow.

Each of these labs will be able to process tens of thousands of tests per day and we’re introducing automation into those processes which really ramps up the capacity.

We are currently on track to reach 100,000 tests a day. In fact, we’re somewhat ahead of where we thought we’d be at this stage.
