This test is crucial for assessing liver injury, diagnosing liver diseases, and monitoring the treatment of liver diseases as well as the adverse effects of drugs that may harm the liver. It checks for levels of total protein, albumin, globulin, albumin/globulin ratio, total bilirubin, direct bilirubin, indirect bilirubin, alkaline phosphatase (ALP), aspartate aminotransferase (AST), and alanine aminotransferase (ALT).
ALT, AST, ALP, and bilirubin levels can indicate liver injury. ALT is more specific to the liver compared to AST. High levels of ALT and AST suggest liver cell injury, while high ALP and bilirubin levels suggest bile duct issues. High direct bilirubin levels can point to liver or bile duct problems. Albumin levels can show how well the liver is making proteins, which is a sign of its overall health.
This test is especially useful for people taking medications that might harm the liver, those with viral hepatitis, signs of chronic liver disease, risk factors for liver disease, or a family history of liver issues.
Understanding the results of each component can help in diagnosing specific liver conditions. Sometimes, further tests may be needed to clarify the results.
It's important to remember that liver enzymes show liver injury, not how well the liver is functioning. Tests like bilirubin, albumin, and prothrombin time can give a better picture of the liver's health.
Results should be viewed in the context of your overall health and history.
