Zusammenfassung:	Apparatus for detecting contaminants, including emboli, in a blood sample prior to blood cell analysis, wherein fluid density sensors are arranged on opposite sides of a fluid segmenting valve to provide electrical signals indicative of the degree of optical opacity of the fluid flowing through the sensors. The derived signals are compared against a diluent reference level signal to provide resultant signal outputs indicating the presence or absence of emboili or other contaminants within the segmented portion of fluid.
