Presence of predominant alkaline phosphatase elevation and positive AMA antibody establishes the diagnosis of PBC.16 Liver biopsy is indicated if the AMA is negative or is in low titers and if associated AIH or NAFLD is suspected.

The normal range for aminotransferase levels in most clinical laboratories is much lower than that for the alkaline phosphatase level. Our mission at Medchunk is to provide the highest quality medical information service to healthcare professionals and patients. Both AST and ALT are enzymes - proteins that accelerate chemical reactions.. AST is non-specific to the liver; this means it can be found in other organs of the body, and its levels can be elevated for a number of different reasons, such as a heart attack, acute pancreatitis or some infections, like mononucleosis.. ALT is also a non-specific enzyme. This is described in multiples of the ULN. Acute inflammation outside the liver may also falsely elevate the results of serum-based iron tests.

The formula to calculate the score is as follows: MDF = 4.6 (patient's prothrombin time control prothrombin time) + total bilirubin (mg/dL). Bone Disease- The bone disease is among the most common causes of elevated alkaline phosphatase. It is useful to categorize liver diseases into three broad categories: hepatocellular, cholestatic, and infiltrative. For women younger than 45 years, a GGT level greater than 27 units per litre is considered high. Anemia and an elevated reticulocyte count are usually present in such cases (Table 4).
