Methods and apparatuses are described for performing a patient-specific immunotherapy procedure. A computing device receives a request to create transfected T cells for a patient. The computing device generates a patient-specific identifier associated with the cell order request. The computing device initiates a process to create transfected T cells for infusion into the patient's bloodstream, comprising: performing a leukapheresis procedure on a sample of the patient's blood to collect T cells from the sample, transferring the collected T cells to a container, labeling the container with the patient-specific identifier, transmitting the collected T cells to a manufacturing facility, creating transfected T cells from the collected T cells using a cell modification technique, receiving the transfected T cells from the manufacturing facility, and infusing the transfected T cells into the patient's bloodstream. The computing device records a tracking event for each step, including the patient-specific identifier, to generate a chain of custody of the patient's T cells.
