A device for conducting a blood sedimentation rate test in the primary blood collecting vessel. The invention provides a plunger (14) for the primary blood collecting vessel (10), a calibrated measuring tube (12) connected to the plunger, and a pressure actuated, normally closed valve (24, 26) in the plunger operative between the blood collecting vessel and the calibrated measuring tube. In the operation of this device, blood is transferred directly from the primary blood collecting vessel to the calibrated measuring tube without intermediate handling. |
