Abstract
A device for rapidly performing a sedimentation-rate test is described. A tube (17) containing a given amount of blood specimen is placed in a holder (13, 21, 22) which rotates (23) the tube (17) a predetermined number of revolutions at a given speed about an axis perpendicular to the longitudinal axis of the tube while rotating (24) the tube about its longitudinal axis, to then stop the tube for a given period of time about 60.degree. from the vertical, and to finally turn the tube (17) to the vertical position at a speed which is but a fraction of the first-mentioned speed also while turning the tube about the longitudinal axis. Means (26) are arranged to monitor the rotational movements of the tube, preferably by means of markings on a plug (18) closing the tube end.
