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 determine a level of an analyte of interest. A pump unit is coupled to the fluid transport network and 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 a trend display portion that includes a trend indicator, which depicts a trend in determined levels of the analyte of interest. The trend display portion also includes at least one of a high-level indicator corresponding to a relatively high level of the analyte and a low-level indicator corresponding to a relatively low level of the analyte.
