Definition / General
  • Liver is site of production of most coagulation factors, but response of each factor to liver disease is variable due to differences in biologic half lives and acute phase reactions
  • PT usually prolonged first, then PTT
  • Factor VII: shortest biologic half life, often affected earliest with largest decrease in serum level
    • Factor VII also decreases earliest with warfarin treatment
  • Factor VIII: may be normal or elevated due to acute phase reaction
  • Factors XI and XII: long biologic half lives, may be normal until liver disease is advanced
