Background: The study of coagulation can be traced back to about 400 BC and to the father of Medicine, Hippocrates. Liver is an important organ of the body having functions of synthesis of plasma proteins and a range of blood clotting factors being produced, some of them exclusively in the organ. All of them are deranged in various liver disorders .Liver plays a predominant role in the regulation of haemostasis. Both cellular and plasmatic coagulation are defective, representing a hallmark of advanced liver disease. Laboratory tests, coagulation tests and liver function tests are useful in the evaluation, management and assessment of prognosis. They provide a sensitive, noninvasive method of screening for the presence of liver dysfunction
