Abstract
Method for the study of the sedimentation characteristics of whole blood comprising the steps of cyclically applying greater than gravity force laterally to a thin, substantially vertically oriented column of whole blood, and rotating the column about 180 degrees about its own axis between each cycle. The sample columns are placed in tubes arranged with their long axes oriented substantially parallel to the axis of rotation of a centrifuge and the tubes are rotated about their own long axes between each cycle and only when at or substantially at rest. A preferred test operation using four cycles of 45 second duration is described with the rotation of the columns being effected by reversal of the direction of rotation of the centrifuge head at the end of each cycle. Other cycle durations are described for providing results correlatable with standarized sedimentation test procedures.
