ABSTRACT:
The disclosure relates to a method of introducing a liquid into a measuring tube and to a device for use in the method. In the specific embodiment the method is used in determining the erythrocyte sedimentation rate of a blood sample. This involves the steps of providing a device comprising a transparent tube and a cap fitted in airtight fashion to a first end portion of the tube and having a skirt which makes airtight sealing engagement with the tube. The cap is slidable along the tube from a first position to a second position closer to the first end of the tube, while still maintaining airtight sealing engagement. A second end portion of the tube is immersed in a blood sample and the cap is slid along the tube towards its said second position to draw a column of blood into the tube. The tube is then removed from the sample and the device is maintained in an upright position for a predetermined length of time. At the end of that time, the extent to which erythrocytes in the blood have settled is determined and provides an indication of the erythrocyte sedimentation rate of the blood sample.
