High glycinyl proline dipeptide aminopeptidase is considered to be a result of hepatobiliary disease, because glycinyl proline dipeptide aminopeptidase is mainly found in bile, and the normal range for normal adults is 44-116 U/L. High glycinyl proline dipeptide aminopeptidase is mainly caused by excessive bile secretion in the body, and clinically, many types of hepatobiliary diseases can cause bile secretion Many types of liver and biliary diseases can cause abnormal bile secretion, such as viral hepatitis, liver cancer, gallstones, etc. Under normal circumstances, the higher the level of glycylopeptidyl dipeptide aminopeptide in the patient’s body, the more serious the disease is. For patients with high levels of glycylopeptidyl dipeptide aminopeptide, they need to go to a regular hospital for more detailed examination, such as liver function test, ultrasound examination, biopsy, etc., in order to identify the cause and receive standardized treatment.
