A 45-year-old woman presents to the emergency department with a 1-week history of jaundice, anorexia, and right upper quadrant discomfort. On examination she is icteric, with a tender right upper quadrant and liver span of 14 cm. There is no shifting dullness or pedal edema and the heart and lungs are normal. On further inquiry, she reports consuming 1 bottle of wine a day for the past 6 months. Which of the following laboratory tests is most characteristic of a patient with jaundice secondary to alcoholic hepatitis?

**Core Concept**
Alcoholic hepatitis is a type of liver inflammation caused by excessive alcohol consumption, leading to jaundice, anorexia, and right upper quadrant discomfort. The condition is characterized by liver cell injury, inflammation, and fibrosis.

**Why the Correct Answer is Right**
In alcoholic hepatitis, the liver's ability to metabolize alcohol is impaired, leading to the accumulation of toxic substances that cause liver cell injury. The condition is often associated with elevated levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) enzymes, which are released into the bloodstream due to liver cell damage. However, the most characteristic laboratory finding in alcoholic hepatitis is an elevated aspartate aminotransferase (AST) to platelet count ratio index (APRI), but more commonly an elevated gamma-glutamyl transferase (GGT) to alanine aminotransferase (ALT) ratio, and an elevated alkaline phosphatase (ALP) level.

**Why Each Wrong Option is Incorrect**
**Option A:** Elevated bilirubin levels are a common finding in jaundice, but they are not specific to alcoholic hepatitis and can be seen in other liver conditions.

**Option B:** Elevated creatinine levels may indicate kidney dysfunction, which can be a complication of liver disease, but they are not a characteristic finding in alcoholic hepatitis.

**Option C:** Elevated white blood cell count may indicate an inflammatory response, but it is not a specific marker for alcoholic hepatitis.

**Clinical Pearl / High-Yield Fact**
In alcoholic hepatitis, the AST to platelet count ratio index (APRI) may be elevated, but more commonly an elevated GGT to ALT ratio and an elevated ALP level are seen. These findings can help differentiate alcoholic hepatitis from other causes of jaundice.

**Correct Answer:** Elevated GGT to ALT ratio.

✓ Correct Answer: B. ratio of AST : ALT is 2 :1 and the AST is 250 U/L
