Abstract:
1. An analyzing method of a blood coagulation reaction by detecting an optical change of a blood sample with an elapse of time, the method comprising the steps of: setting a checkpoint or check region between the start of the reaction and the end of reaction, and monitoring a reaction state of the reaction by: computing a check item at the checkpoint or check region; comparing the check item with a predetermined threshold value; and judging the presence or absence of abnormality of the blood coagulation reaction based on the compared result; wherein the check item is selected from the group consisting of a first item, a second item, a third item and a fourth item, the first item being a first time required for changing from a first optical detecting value to a second optical detecting value, the second item being an amount of optical change in a predetermined time range, the third item being a ratio between a second time required for changing from a third optical detecting value to a fourth optical detecting value and a third time required for changing from a fifth optical detecting value to a sixth optical detecting value, and the fourth item being a fourth time required for reaching a predetermined optical detecting value.
