Factor II (Prothrombin), DNA Analysis
Also known as: Prothrombin DNA, Prothrombin Gene Analysis, Prothrombin Gene Mutation
Use
Contributes to the risk assessment for venous thromboembolis thromboembolism (VTE) to better inform decisions regarding treatment and clinical management decisions of patients with relevant personal history of VTE and potential preventative care for patients with significant family history of VTE.
Special Instructions
Genetic coordinators are available for health care providers to discuss results and for information on how to order additional testing. Results cannot predict the occurrence or recurrence of a thrombotic event.
Limitations
The variant analyzed is c.*97G>A, previously referred to as G20210A. Results must be combined with clinical information for accurate interpretation. Molecular-based testing is highly accurate, but diagnostic errors may occur due to factors such as genetic variants, blood transfusions, bone marrow transplantation, somatic or tissue-specific mosaicism, mislabeled samples, or erroneous representation of family relationships. This test has not been cleared or approved by the FDA.
