What is liver function classification?

There are many criteria for liver function classification, among which Child-Pugh classification is the most common and can be divided into three grades. Child-Pugh

scoring system evaluates liver function by evaluating the presence or absence of serum bilirubin, albumin, prothrombin time, ascites and encephalopathy. It can be divided into three grades, namely A, B and C. Grade A indicates good liver function, usually no or only mild clinical symptoms, and the prognosis is the best. Grade B indicates moderate impaired liver function, mild clinical symptoms and laboratory abnormalities. The 1-2 year survival rate of patients is between 60% and 80%. Grade C indicates severe impairment of liver function, marked clinical symptoms and severe laboratory abnormalities, and generally poor prognosis, with a 1-2 year survival rate of 35%-45%.
