Abstract: An optical detection assembly for monitoring a biological fluid in a vessel includes two fluid-adjustment structures, which are spaced apart and configured to receive at least a portion of a biological fluid-containing vessel therebetween. A light source (which may be associated with one of the fluid-adjustment structures) is configured to emit light through a thickness of the biological fluid in the vessel, while a light detector (which may be associated with the other one of the fluid-adjustment structures) is configured to receive at least a portion of the light from the light source after it has passed through the biological fluid in the vessel. At least a portion of at least one of the fluid-adjustment structures is configured to move with respect to at least a portion of the other one so as to change the thickness of the biological fluid in the monitored portion of the vessel.
