    Inherited protein C deficiency is considered a stronger thrombophilia. It increases the risk for venous and arterial thromboembolism, and possibly for early and late pregnancy loss and other adverse pregnancy outcomes (preeclampsia, IUGR, placental abruption).  There are 2 major causes for low protein C values:

  • How common is pregnancy loss? What are the causes? Pregnancy loss  in the general population is common. Most losses occur in the first trimester. As many as 5 % of women have 2 or more early losses; 1-2 % have 3 or more early losses [ref 1]. Well established risk factors for pregnancy loss are:

While smaller-volume physician practices may well have appropriate criteria in place, structured anticoagulation clinics often have the expertise and resources for optimal anticoagulation management. The location of a number of anticoagulation clinics in the U.S.
