Which of the following markers is used to evaluate liver excretory function and is typically elevated in liver disorders involving bile flow obstruction?
Understand the Problem
The question is asking which laboratory marker is specifically used to assess liver excretory function and is known to be increased in liver conditions that block bile flow.
Answer
Serum bilirubin is used to evaluate liver excretory function in bile flow obstruction.
The marker used to evaluate liver excretory function and is typically elevated in liver disorders involving bile flow obstruction is serum bilirubin.
Answer for screen readers
The marker used to evaluate liver excretory function and is typically elevated in liver disorders involving bile flow obstruction is serum bilirubin.
More Information
Bilirubin is produced by the breakdown of red blood cells in the liver and is excreted in bile. Elevated levels suggest issues with bile flow, commonly seen in conditions such as gallstones or tumors.
Tips
A common error is confusing bilirubin with other liver enzymes like ALT or AST, which indicate liver cell damage rather than bile flow obstruction.
