The Glasgow Alcoholic Hepatitis Score (GAHS) is a prognostic score. That means it helps doctors estimate how an illness may go in the near term. It is used in alcohol-associated hepatitis (AH), also called alcoholic hepatitis. In AH, the liver becomes inflamed and injured after heavy drinking.
The American Association for the Study of Liver Diseases (AASLD) says doctors rate how severe AH is with validated prognostic scores. These tools help find people at high risk of short-term death and help guide treatment choices. The guidance names the Maddrey discriminant function and the MELD score as examples, and notes there are others. GAHS belongs to this group of scores.
GAHS does not diagnose AH. Doctors usually make that diagnosis from your alcohol history, symptoms, and lab results, and a liver biopsy is not routinely needed. GAHS is also not a scan or a procedure.
The name can cause mix-ups. GAHS is not the Glasgow Coma Scale, which rates brain function, and it is not the Glasgow-Blatchford Score, which sorts bleeding risk in the digestive tract.
