Clinical Info |
This assay enumerates the absolute count of CD34+ hematopoietic progenitor stem cells. Their viability is also assessed. Flow cytometric evaluation of CD34+ cell level is necessary for measuring quantitatively the hematopoietic progenitor cells in dose requirement protocols of stem cell transplantation. Quantification of CD34+ cells is also used during mobilization of hematopoietic cells and leukophoresis procedures. |
