Cobas Factor II and Factor V Test

  

Thrombophilia is a condition with a predisposition to develop thrombosis (e.g., blood clots) due to either an inherited or acquired defect in the coagulation system. Blood clots may form in either the venous or arterial vascular system and can lead to Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE), which are the third most common cause of cardiovascular death after acute coronary syndrome and stroke.

Inherited thrombophilia is most frequently caused by a Factor V or Factor II (Prothrombin) gene mutation. The Factor V Leiden mutation is a single point mutation (G to A at position 1691, or G1691A) of the human Factor V gene that results in substitution of arginine to glutamine at position 506 (R506Q) in the Factor V protein. Factor V Leiden mutation renders the protein partially resistant to inactivation by activated protein C (APC). Factor V Leiden mutation has a relatively high prevalence in the general population (e.g. about 5% in Caucasians). In addition to the Factor V G1691A mutation, molecular genetic testing for Factor II G20210A (G to A at position 20210) is recommended as this mutation is present in 1-3% of the general population. Evaluation of a patient’s risk for hereditary thrombophilia through a Factor II and Factor V genotyping test is critical for diagnosis and clinical management of patients with thrombophilia.
