Abstract
A method is provided for calibrating sensors used to analyze characteristics of physiologic fluids such as blood. The method involves the use of a sensor assembly having an analyte-responsive sensor in communication with a passageway which is in divertable fluid communication with a physiologic line and a conduit by which a reference sample may be introduced into the passageway. The method involves exposing the sensor to the reference sample, thereby producing a sensor response. The method also allows performing quality control on the sensors. Also provided is an apparatus with which the claimed method may be practiced.
