About the test
This test is crucial for assessing liver injury, diagnosing liver diseases, and monitoring the treatment of liver conditions or the adverse effects of drugs that may harm the liver. It measures various components such as total protein, albumin, globulin, albumin/globulin ratio, total bilirubin, direct bilirubin, indirect bilirubin, alkaline phosphatase (ALP), aspartate aminotransferase (AST), and alanine aminotransferase (ALT).
Why is this test important?
This panel helps in evaluating liver health by checking for liver injury and function. It distinguishes between different types of liver injuries and can be particularly useful for people taking medications that might affect the liver, those with viral hepatitis, chronic liver disease symptoms, high risk of liver disease, lifestyle factors for nonalcoholic fatty liver disease, or a family history of liver disease.
What does it measure?
- ALT and AST levels to assess liver cell injury.
- ALP and bilirubin levels to check for bile duct problems.
- Albumin and total protein levels to evaluate the liver's ability to make proteins.
Who might need this test?
Providers might recommend this test for individuals showing signs of liver issues, those with a family history of liver disease, or individuals at risk due to lifestyle or medication use.
Included biomarkers & Reference ranges
| Biomarker | Reference range |
|---|---|
| Alkaline Phosphatase (ALP) An enzyme found mainly in the liver and bones. High levels can signal liver disease, bile duct blockage, or bone conditions. | 35–150 IU/L |
| Alanine Aminotransferase (ALT) A liver enzyme released into the blood when liver cells are damaged. One of the main markers used to screen for liver inflammation or injury. | 6–29 IU/L |
| Aspartate Aminotransferase (AST) An enzyme found in the liver, heart, and muscles. Elevated levels can point to liver damage, though it's less liver-specific than ALT. | 10–35 IU/L |
| Albumin The main protein made by your liver, which helps balance fluids and carries hormones, vitamins, and medications through your blood. Low levels can point to liver, kidney, or nutrition issues. | 3.6–5.1 g/dL |
| Albumin/Globulin Ratio Compares your two main blood protein types, albumin and globulin. An abnormal ratio can point toward liver disease, kidney problems, or immune system conditions. | 1–2.5 Ratio |
| Direct Bilirubin The form of bilirubin already processed by your liver. Elevated levels point toward a liver or bile-duct problem rather than red blood cell breakdown. | 0–0.2 mg/L |
| Globulin A group of blood proteins that includes antibodies and various transport proteins. Assessed together with albumin to evaluate liver, kidney, and immune function. | 1.9–3.7 g/dL |
| Indirect Bilirubin The form of bilirubin not yet processed by your liver, produced from the normal breakdown of red blood cells. Elevated levels can point to increased red blood cell breakdown or a liver processing problem. | 0.2–1.2 mg/dL |
| Total Bilirubin The combined level of both processed and unprocessed bilirubin in your blood, a byproduct of red blood cell breakdown. Used to evaluate liver function and jaundice. | 0.2–1.2 mg/dL |
| Total Protein The combined amount of all proteins in your blood, mainly albumin and globulins, used to help evaluate liver, kidney, and nutritional status. | 6.1–8.1 g/dL |
