BACKGROUND Successful hematopoietic engraftment depends on the number of viable CD34+ stem cells. Therefore, accurate quantification of viable CD34+ stem cells is required. STUDY DESIGN AND METHODS To evaluate clinical laboratory performance, the New York State Department of Health initiated proficiency testing (PT) for viable CD34+ stem cells. Preserved adult peripheral blood was spiked with preserved cord blood CD34+ stem cells and was shipped to the participating laboratories. Three… CONTINUE READING
