Coagulation Factors Information and Side Effects
The coagulation of blood is a complex process during which blood forms solid clots. It is an important part of hemostasis whereby a damaged blood vessel wall is covered by a fibrin clot to stop hemorrhage and aid repair of the damaged vessel. Disorders in coagulation can lead to increased hemorrhage and/or thrombosis and embolism.
... Why get tested?
To determine whether one or more of your coagulation factors is missing, deficient, or dysfunctional.
When to get tested?
When you have unexplained or prolonged bleeding, an abnormal Prothrombin Time (PT) or activated Partial Thromboplastin Time (aPTT) test, or have a relative with a hereditary coagulation factor deficiency. Sometimes when your doctor wants to monitor the severity of a factor deficiency and the effectiveness of treatment.
