Abstract
An embodiment of a system for analyzing a body fluid of a patient comprises a fluid transport network having a patient end configured to provide fluid communication with the body fluid in the patient and a fluid delivery point spaced from the patient end. A pump system is coupled to the fluid transport network. The pump system has an infusion mode in which the pump system is operable to pump an infusion fluid toward the patient end of the fluid transport network and a draw mode in which the pump system is operable to draw the body fluid from the patient into the fluid transport network through the patient end. At least one electrochemical test element is located near the fluid delivery point of the fluid transport network. The electrochemical test element is positioned to receive a portion of the body fluid delivered to the delivery point by the fluid transport network. An analyte detection system is configured to receive the test element and to measure at least one analyte in the portion of the body fluid.
