Abstract

A method for continual monitoring of a physiologic analyte in a subject includes steps of contacting the subject with a collection reservoir such that the analyte can move from the subject into the collection reservoir, the contents of the collection reservoir being in operative communication with a detector, collecting the analyte in the collection reservoir, using the detector to detect the analyte in the collection reservoir, and, once the analyte has been detected, rendering the analyte undetectable by the detector.
Also, apparatus for continual monitoring of a physiologic analyte in a subject includes a collection reservoir for receiving the analyte from the subject, the contents of the collection reservoir being in operative relationship with a detector that detects the analyte in the reservoir, and means for rendering the analyte, once detected, undetectable by the reservoir.
