You asked

​Can you please confirm that after the World Health Organisations recent announcement advising against the use of testing for Covid-19 at too high cycles, the UK will now be lowering it to the recommended cycle.

Please confirm this and the number of cycles used previously and the number now being used after the change of advice from WHO.
