“At hospital, you’ll probably be given an injection of anticoagulant medicine before you get any test results.”
Some risk factors put certain people at higher risk for developing a blood clot. Sometimes, a blood clot in a vein can occur with no apparent underlying risk factor.
Blood clots become more common as people get older, especially when they are over age 65. Moreover, you can be at higher risk if you have a family history of blood clots.
