Validation techniques for fluid delivery systems

A method comprising:

• providing a fluid delivery system that includes a medical fluid container, a fluid pressurizing unit, and a fluid transfer set, wherein the fluid transfer set is connected to transfer a fluid from the medical fluid container to the fluid pressurizing unit;
• drawing the fluid from the medical fluid container, through the fluid transfer set, and into the fluid pressurizing unit so that the fluid transfer set and fluid pressurizing unit are filled with the fluid;
• placing a discharge outlet of the fluid pressurizing unit in fluid communication with a fluid reservoir containing a tracking fluid, wherein the tracking fluid contains a tracking agent, and wherein the fluid reservoir is closed so that the fluid pressurizing unit cannot draw the fluid from the medical fluid container and discharge the fluid into the fluid reservoir;
• operating the fluid pressurizing unit so as to pressurize a portion of the fluid in the fluid pressurizing unit;
• extracting one or more samples of the fluid from at least one of the medical fluid container, the fluid transfer set, and the fluid pressurizing unit;
• and
• analyzing the one or more samples to determine a concentration of the tracking agent in the at least one of the medical fluid container, the fluid transfer set, and the fluid pressurizing unit.
