Abstract

A test value corresponding to blood subsidence from a syllectogram is determined as a result of the effect of shearing forces on a blood sample, by ascertaining the slope of the test curve representing the syllectogram at a predetermined time beginning with or after the onset of the blood aggregation phase as the test value after: PA1 (a) sudden stoppage of the shearing; or PA1 (b) a transition to a continuous minor residual shearing.
