<qa>  What is the name of the new clinical protocol that will include blood samples taken from the patient duringIn light of the recent guidelines, the proposed new clinical protocol will include blood samples taken from the patient during the in-patient stay. On the day of treatment, blood samples will be taken at 2h and 6h after radioiodine administration, at the same time as the clearance measurements. Thereafter, a blood sample will be taken from the patient once per day, at the same time as one of the clearance measurements. In addition, a further blood sample will be taken when the patient attends for whole-body and SPECTCT scans. These blood samples will then be analysed in the laboratory using standard radiation measurement procedures to determine the blood dose according to the European guidelines.
