Thrombophilia

Hereditary defects in one or more of the clotting factors can cause the formation of potentially dangerous blood clots (thrombosis). Approximately 5-8% of the U.S. population has one of these clotting disorders collectively called thrombophilia, a propensity for blood clotting in which a genetic defect can be identified that often results in thrombosis.

More than 60,000 Americans die each year from venous thromboembolism; in addition, nearly half of patients with deep vein clots experience long-term health consequences that adversely affect their quality of life.
