The CTP uses 5 clinical and laboratory parameters—ascites, hepatic encephalopathy, international normalized ratio [INR], serum albumin, serum total bilirubin—to score the severity of liver disease on a scale from 5 to 15 and categorize patients into CTP class A, B, or C. Historically, the CTP score was developed to guide selection of candidates for surgery for portal hypertension (portocaval shunting and transection of the esophagus) and subsequently was utilized in liver transplant allocation [27, 33, 34]. Here, ALB is linked to liver disorder.
