Obstetrical disseminated intravascular coagulation (DIC) is usually a very acute, serious complication of pregnancy. The DIC diagnostic criteria in obstetrics (the obstetrical DIC score) help with making a prompt diagnosis and starting treatment early. These DIC diagnostic criteria, in which higher scores are given for clinical parameters than for laboratory parameters, have three components: (1) the underlying disease, (2) clinical symptoms, and (3) laboratory findings. It is justified that it is appropriate to initiate therapy for DIC when the obstetrical DIC score reaches 8 points or more before obtaining the results of coagulation tests.
