Plans for the collection, laboratory evaluation and storage of biological specimens for genetic or molecular analysis in this trial/for future use {33}
An additional informed consent will be obtained for the sub-study ‘biobank’. Participation in the sub-study is not a prerequisite for participation in the TTVguideIT study. Within this sub-study, biological material (serum, plasma, whole blood and urine) will be sampled and stored centrally at the Medical University of Vienna for further immunological monitoring, including but not restricted to further DSA assessment, donor-derived cell-free DNA, gene expression, and urinary TTV and chemokines.
