What Is Antithrombin?
Antithrombin is a naturally occurring mild blood thinner in our blood and protects our blood from clotting too much or abnormally. If antithrombin levels are low a child's blood will have a tendency to clot too much.
What Is Antithrombin deficiency?
Antithrombin deficiency is an inherited disorder and significantly increases the chance of the development of abnormal blood clots. Approximately half of those with this blood clotting disorder will develop at least one abnormal blood clot, usually after adolescence. These blood clots may cause deep vein thrombosis or pulmonary embolism.
