The Optimal Time of Peripheral Blood Hematopoietic Stem Cell Collection for Autologous Transplantation May Be Predicted By Immature Granulocytes and Nucleated Red Blood Cells

The time of initiating stem cell collection is very important for successful transplantation and determined according to peripheral blood CD34+ count analysed by flow cytometry. In this study, we aimed find the role new complete parameters determine optimal collection. Eighty-six patients who underwent mobilization were included in study. Peripheral cells on same day. Patients with CD 34+ counts ≤ 20/μL > as Group 1 2, respectively. difference CBC between 2 groups relationship these evaluated. It was found that immature granulocytes ratio, nucleated red ratio positively correlated significantly different two (P< 0.001, P= 0.011 0.012, respectively). index formulated using ratios (P<0.001), had highest diagnostic accuracy (AUC= 0.766). Immature can be used faster cheaper compared
