Introduction: In order to carry out an autologous transplantation, hematopoietic stem cells should be mobilized to peripheral blood and later collected by apheresis. The CD34+ cell count is a tool to establish the optimal time to begin the apheresis procedure. Objective: To evaluate the association between peripheral blood CD34+ cell count and the successful collection of hematopoietic stem cells. Materials and methods: A predictive test evaluation study was carried out to establish the usefulness of peripheral blood CD34+ cell count as a predictor of successful stem cell collection in patients that will receive an autologous transplantation. Results: 77 patients were included (median age: 49 years; range: 5-66). The predominant baseline diagnosis was lymphoma (53.2 %). The percentage of patients with successful harvest of hematopoietic stem cells was proportional to the number of CD34+cells in peripheral blood at the end of the mobilization procedure. We propose that more than 15 CD34+cells/μL must be present in order to achieve an adequate collection of hematopoietic stem cells. Conclusion: Peripheral blood CD34+ cell count is a useful tool to predict the successful collection of hematopoietic stem cells.
