An automated peritoneal dialysis system and machine configured to perform dextrose mixing are disclosed. An example dialysis machine includes a pump, a first solution having a first formulation stored in a first container that is placed in fluid communication with the pump, and a second solution having a second formulation stored in a second container that is also placed in fluid communication with the pump. The first container has a first unique identifier indicative of the first formulation and the second container has a second unique identifier indicative of the second formulation. The dialysis machine also includes a logic implementer programmed to receive a therapy prescription and operate the pump if the first formulation indicated by the first unique identifier is specified by the therapy prescription, or the second formulation indicated by the second unique identifier is specified by the therapy prescription.
