Abstract

An apparatus and method for measuring conductance are provided. The method and apparatus are particularly well adapted for use with a removable or replaceable cartridge in a blood analysis system. The apparatus generally involves providing a system having a first, unfiltered, conductance measurement cell and a second, filtered, conductance measurement cell. The preferred method involves relating values measured in the two cells for a whole blood sample and for a known calibrant together, to obtain a value, for example hematocrit, for the unknown whole blood sample.
