Introduction: Stem cells for autologous and allogenic transplantation are obtained from several sources including bone marrow, peripheral blood or cord blood. In addition, a non-flow cytometry-based method, the microvolume fluorimetry-based STELLer CD34 assay, has demonstrated excellent analytical performance [ 15 , 17 ]. However, some flow cytometers are equipped with the ability to provide the absolute volume of cell suspension analyzed 3. van Wieringen,3 Jaco Kraan,4 Wil A.
