Zusammenfassung:	Method and apparatus for detecting contaminants, including emboli, in a fluid sample prior to sample testing, 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 to an operator or a monitoring device the presence or absence of emboli or other contaminants within the segmented portion of the fluid.
