Could you please tell me what the Cycle Threshold value used was for PCR rests for COVID 19 in the period March to Dec 2020 and for the period Jan 21 to end Feb 21?

Thank you for your request.
Public Health England (PHE) are responsible for PCR testing so would be better placed to assist with your query. They can be contacted via email at wn_coronavirus@phe.gov.uk
