Coagulation factor V activity

Coagulation factors are proteins in your blood. They help form blood clots to stop bleeding when you have an injury. These proteins are also called clotting factors. You have several different types of clotting factors that are all important for making blood clots.

A coagulation factor test is used to find out if you have a problem with any of your clotting factors that may cause too little or too much blood clotting.
