Abstract

A method calibrates a monitor (100) that comprises a non-invasive blood constituent monitor (102) and a traditional measurement system (116). The non-invasive blood constituent monitor includes a thermal gradient inducing element (110) an analyzer window (108). A traditional monitor output representing a property of a blood constituent is generated by the traditional measurement system (116). A non-invasive monitor output representing the property of the whole blood constituent is generated by the non-invasive constituent monitor (102). The traditional monitor output and the non-invasive monitor output is corrected by the amount of error.
