Assessment of haemostasis in pregnant women: A retrospective evaluation of the diagnostic performance of the HEMSTOP standardised questionnaire
Authors' conclusion
In the conditions of our study, the HEMSTOP questionnaire enables the prediction of a primary haemostatic anomaly with a specificity and sensitivity comparable to routine haemostatic assessments.
