COAG FACTOR IX ACT 0000352

Coagulation Factors are used to determine whether levels of one or more of your coagulation factors are increased, normal, or decreased. Your doctor will check these when you have unexplained or prolonged bleeding, an abnormal Prothrombin Time (PT) or Partial Thromboplastin Time (PTT) test, or have a relative with a hereditary coagulation factor deficiency. You could also be tested when your doctor wants to monitor the severity of a factor deficiency and/or the effectiveness of treatment.
