Which laboratory finding could indicate acute pancreatitis?

Elevated lipase levels are a hallmark laboratory finding associated with acute pancreatitis. The pancreas releases lipase, an enzyme responsible for breaking down fats, into the bloodstream, particularly when it is inflamed or injured. In the context of acute pancreatitis, lipase levels can be significantly elevated, often more than three times the normal range, which serves as a key diagnostic marker for the condition.

In contrast to lipase, other laboratory findings such as increased ALT are more indicative of liver issues rather than pancreatic conditions. Decreased white blood cells are not associated with pancreatitis and don't typically indicate inflammation or an acute process. Low bilirubin levels may occur in some cases of pancreatitis, particularly if there is no obstruction of the bile ducts, but they do not serve as a specific indicator of the condition. Therefore, the elevation of lipase is the most reliable laboratory marker for diagnosing acute pancreatitis.
