Managed to get through the videos, very slowly. Thank you so much @Andy and Dr Morten. Some further questions/ideas which would be good to know at some point please? - when Dr M referred to “the Biobank”, was he referring to the U.K. Biobank or the U.K. ME/CFS Biobank? - when wanting to duplicate blood retrieval procedure (between Oxford, Newcastle, Spain & Poland - fingers crossed for some funding), I suggest they have conversations with the U.K. ME/CFS Biobank whose nurses already have a strict order/collection procedure when dealing with each patient’s appointment. - has Dr M spoken with U.K. ME/CFS Biobank to see whether they have any Severe ME patients on a participant waiting list (Newcastle/Oxford directions)? Obviously the patient themselves would have to be approached to see whether they were prepared to go onto the Oxford study instead of (/as well as ? a future) ME Biobank study.
