Primary Outcome Measures
NameTimeMethod
ROTEM lysis, EXTEM/FIBTEM/ABTEM (i.e. LT, LOT, Li (t), ML, CLR), measured on the day of the blood draw
Secondary Outcome Measures
NameTimeMethod
ADAMTS13 plasma determinations (antigen, activity, conformation, degradation) <br>Plasma turbidity (time to onset, slope, degree) <br>Whole blood clot lysis, using HALO assay (time to onset, slope, degree), <br>Platelet activation (CD62P, PAC1), using flow cytometry <br>Platelet adhesion and aggregation, using flow model (Time to platelet adhesion, aggregation and breakdown of clots, measured using fluorescent live-cell imaging). <br><br>*There will be only one blood draw (and thus one timepoint) for the volunteer. All outcomes except the ADAMTS plasma determinations. will be measured on the day of thid blood draw. The ADAMTS13 plasma determinations will be performed on a later moment on frozen plasma obtained from the inital blood draw.
