Quick Facts
- Sample: Blood
- Fasting: Fasting for 8-10 hours is required.
- Turnaround: 1-2 business days. May take longer based on weather, holiday, or lab delays.
What's Included
Cholesterol, Total
Hepatic Function Panel
- Protein, Total: Assesses overall protein levels related to liver and kidney function.
- Albumin: A major protein tied to healthy liver and kidney function.
- Globulin (Not Included with LabCorp): A major protein group involved in clotting and infection-fighting antibodies.
- Albumin/Globulin Ratio (Not Included with LabCorp): Calculated by dividing albumin by globulin.
- Bilirubin, Total: Measures the total amount of bilirubin in your blood.
- Bilirubin, Direct: The direct portion of bilirubin.
- Bilirubin, Indirect (Not Included with LabCorp): The indirect portion of bilirubin.
- Alkaline Phosphatase: A protein associated with liver and bone health.
- AST (SGOT): An enzyme used to evaluate liver function.
- ALT (SGPT): An enzyme used to help identify liver damage.
LD (Lactic Acid Dehydrogenase)
GGT
Benefits
- Measures liver enzymes, proteins, and bilirubin in one blood draw.
- Includes GGT and LD for additional liver-related enzyme information.
- Adds a total cholesterol measurement alongside your liver markers.
- Includes a calculated albumin/globulin ratio for added context.
- Gives you results online to review and share with your provider.
Who Is This Test For?
- You want a baseline look at your overall liver health.
- You have risk factors for liver disease, such as past hepatitis.
- You have a history of alcohol use and want to check liver markers.
- You take medications that can affect the liver and want to review your levels.

FAQ
1. Do I need to fast or prepare for this test?
Fasting for 8-10 hours is required.
2. How quickly will I get results?
Expect results in 1-2 business days. May take longer based on weather, holiday, or lab delays.
3. What can my results tell me?
Think of this panel as a snapshot built from several angles. Liver enzymes, proteins, and bilirubin show how the liver is working and what it releases into your blood, while total cholesterol adds a separate lipid measurement. Together they give you and your provider a broader picture of liver health, though each group contributes a different kind of information.
4. How do the tests in this panel differ from one another?
The enzymes (ALT, AST, alkaline phosphatase, GGT, and LD) are released from tissues, and several are found in the liver. Total protein, albumin, and globulin are proteins, and the albumin/globulin ratio is calculated by dividing albumin by globulin rather than measured on its own. Bilirubin is a substance the liver processes. Total cholesterol is a separate measurement. Some components differ by lab, with LabCorp excluding indirect bilirubin and globulin.
5. How do I interpret the results?
Single numbers rarely tell the whole story. What matters is the pattern across your enzymes, proteins, bilirubin, and cholesterol, viewed alongside your symptoms, medical history, medications, and other lab findings. Directly measured values, the calculated albumin/globulin ratio, and lab specific components each carry different information, and not every value will move in the same direction. A qualified healthcare provider can help put your results in context.
Disclaimer: Reference ranges may vary by laboratory. Listed ranges are general guidelines and may differ from those used by the performing lab. Always consult your healthcare provider for interpretation.
6. What should I do if my results are abnormal?
Start by sharing your report with a qualified healthcare provider. An out-of-range value does not automatically point to a condition or call for treatment. Your provider can look at how several results fit together and decide whether any further evaluation makes sense for you. Avoid changing any medication or routine on your own based on a result.
