Abstract

An embodiment of an analyte detection system includes a fluid transport network having a patient end configured to provide fluid communication with a body fluid in a patient and a body fluid analyzer accessible via the fluid transport network. The body fluid analyzer is configured to measure a level of an analyte of interest in the body fluid. A pump unit is coupled to the fluid transport network. The pump unit has a sample input mode and an infusion mode. In the sample input mode, the pump unit is operable to transport a sample of the body fluid from the patient end and toward the body fluid analyzer. In the infusion mode, the pump unit is operable to transport an infusion fluid toward and out the patient end. The analyte detection system also includes a user interface for communication with the body fluid analyzer. The user interface includes an input element configured to accept user input corresponding to a patient health event. In some embodiments, the patient health event includes a patient health action or information relevant to clinical interpretation of data pertaining to measured analyte levels.
