Evaluating the effect of sampling site and cryopreservation on blood cell counts for various subpopulations University of Antwerp
This study aims to measure the impact of the sampling site on blood cell counts. For this purpose, blood samples will be drawn via an antecubital vein, a dorsal hand vein and the radial artery. Paired comparisons of red blood cell, platelet and white blood cell counts (including lymphocyte subpopulations using flow cytometry) will be made. Furthermore, we will assess the effect of cryopreservation on lymphocyte subpopulation counts.
