Laboratory evaluations of the suspected hypercoagulability state were found normal, including activated partial thromboplastin time (aPTT), prothrombin time (PT), international normalized ratio (INR), lupus anticoagulant dilute Russell’s viper venom test (LAC dRVVT screen), LAC-sensitive PTT, antithrombin-III, lupus anticoagulant silica clotting time ratio (LAC SCT ratio), protein S antigen, anticardiolipin IgM and IgG, factor V Leiden PCR, and prothrombin (G20210A). Here, F2 is linked to thrombophilia.
