Definition / general
  • Very rare hypercoagulable condition, either hereditary (autosomal dominant, 15 families documented through 2002) or acquired (liver disease)
  • Associated with thrombosis, but not a strong risk factor by itself
  • Testing patients with thromboembolic disease for heparin cofactor II deficiency is not recommended as a first or second line test (Arch Pathol Lab Med 2002;126:1394)
