For confirmed infections: i. laboratory-confirmed BSI based on the isolation of an organism from blood cultures; or ii. If a laboratory-confirmed BSI due to a commensal organism, the presence of at least one of the following signs or symptoms will be required: fever (\>38.0˚C), chills, or hypotension. 4\. Subject agrees to comply with all follow-up evaluations 5\. Subject has provided written informed consent; or if unable to perform informed consent, written informed consent on behalf of the subject has been provided by a legally-authorized representative.

History of or known hypercoagulable state (e.g. Systemic Lupus Erythematosus (SLE), antiphospholipid syndrome/lupus anticoagulant, protein C or S deficiency, antithrombin deficiency, factor V Leiden deficiency, active cancer, sickle cell disease, and history of deep vein thrombosis (DVT)) 14. History of a condition documented in the medical record within 6 months prior to enrollment that may result in an increased risk for thrombosis, including any of the following: 1.
