The following indications of blood typing and crossmatching are based on risk factors for postpartum hemorrhage according to integrated recommendations from the American College of Obstetrics and Gynecology,1 California Maternal Quality Care Collaborative,2 and the guidelines of Beth Israel Deaconess Medical Center (BIDMC) at Boston. Individualized recommendations for type and screen or crossmatch are based on these relative risks (Chapter 34, “Evaluation of Hemorrhage Risks”).
