Abstract
An automated method for determining a coagulation result of a biological sample is presented. The method includes obtaining a time series representing measurement data of a sample. The time series spans a period in which a clotting reaction is supposed to take place. The method includes obtaining a global model function configured to model measurement data of a sample in which a clotting reaction takes place. The global model function is configured to model the measurement data as a sigmoidal shape with at least one inflection point. The absolute value of the maximum curvature of the sigmoidal shape is larger on one side of the at least one inflection point than on the other side. The method includes fitting the model function to the time series representing measurement data to obtain a fitted model function and determining a coagulation result of the sample based on the fitted model function.
