This invention relates in general to the field of cell-therapy treatments and more particularly, but not by way of limitation, to systems and methods for administering personalized cell-therapy treatments intravenously. In various embodiments, the system may calculate an aspiration volume needed for centrifugation to achieve a concentrated target threshold dose of 2×106 platelets/μL for a particular cell therapy using various factors such as, for example, information about a patient and the efficiency of the concentration process.
