A 55-year-old woman presents with a proximal vein DVT without an obvious underlying etiology. She has been treated for 3 months with warfarin and now comes to you for further evaluation. On her initial workup, she had a positive lupus anticoagulant antibody test which was drawn because of a family history of DVT. She was told that she had the antiphospholipid syndrome and would need life-long anticoagulation.

What is the next step in management?

  1. Stop warfarin at 6 months
  2. Repeat the lupus anticoagulant antibody test
  3. Switch warfarin to ASA 324 mg per day
  4. Life-long warfarin therapy
