| Zusammenfassung: | A method for determining a prothrombin time comprises following steps: A blood sample and a light of the light source are provided, and an optical characteristic function indicating relation between the light source and the blood sample is then obtained. Subsequently, a maximum value, a minimum value and an extreme value of derivatives of the optical characteristic function are determined, wherein the maximum value occurs after the minimum value and the extreme value occurs after the maximum value; and the prothrombin time is determined according to the extreme value. |
