Update December 2020: Thank you very much to all contributing RCGP RSC practices for your support in the Convalescent Serology study so far. We kindly ask participating practices to stop recruiting any new patients for Convalescent Serology at this stage. If you have any existing Convalescent Serology patients, please do continue with the follow up blood sampling.
Update February 2021: For patients participating in Convalescent Serology we are now additionally looking for follow up samples at 9 and 12 months after symptom onset. Additionally, the time-frame for samples at 3-6 weeks, 12 weeks, and 20 weeks has been extended. See below for further details.
