Patent ID: 8675185

Claim:
A method for determining the haemolysis of a blood sample, the method comprising: irradiating measuring light on the blood sample after a haemolysis operation on the blood sample has been started, which measuring light is radiated from a measuring light source; detecting measuring light values from the measuring light source at several measuring points of time for measuring at least one of light transmitted through and light reflected by the blood sample with a detector device; comparing several of the measuring light values for different measuring points of time and determining a measure for the haemolysis progress by an evaluation device by receiving the measuring light values detected by the detector device, forming a time-dependent course of light values for the received measuring light values, determining for the time-dependent course at least section-wise a gradient in an assigned measuring curve as a comparative measure for the comparison of the measuring light values at the different measuring points of time, and determine when the gradient is different from zero; and determining the conclusion of the haemolysis when the gradient within a selectable measurement accuracy, after a measuring period in which the gradient is different from zero, falls to a minimum going down to zero.
