The present invention involves, in some embodiments, fluid handling systems and methods for pumping fluid to and from a patient. The system and methods in certain embodiments involve a pumping cartridge and a reusable component configured to mate with the pumping cartridge comprising. The reusable component may comprise a control chamber and a pressure transducer configured to measure a gas pressure associated with the control chamber, and may further include a processor configured to supply the control chamber with a gas at a predetermined pressure, open the pump chamber to the surroundings, monitor the gas pressure associated with the control chamber using the pressure transducer over a predetermined period of time, and determine if the change in gas pressure exceeds a predetermined limit.
