Comprehensive blood test to assess liver function, jaundice, and monitor liver diseases.
A liver function panel measures enzymes and proteins produced by or processed through the liver — the body's largest internal organ and a critical hub for detoxification, protein synthesis, and bile production. The panel typically includes ALT and AST (enzymes released when liver cells are damaged), ALP and GGT (markers of bile duct function), bilirubin (a waste product processed by the liver), and albumin (a protein the liver produces). Elevated levels can indicate liver inflammation, fatty liver disease, hepatitis, alcohol-related damage, or bile duct obstruction. With non-alcoholic fatty liver disease affecting roughly 25% of adults globally, regular liver screening has become increasingly important.
Key Details
Who Is This For?
Anyone who consumes alcohol regularly and wants to monitor liver health. People taking medications that can affect the liver (statins, acetaminophen, certain antibiotics). Those with risk factors for fatty liver disease including obesity, type 2 diabetes, or metabolic syndrome. Individuals with a family history of liver disease or hepatitis.
What's Included
Preparation Required
Fasting for 10–12 hours before your appointment is recommended for accurate results (water is fine). Avoid alcohol for 24 hours and intense exercise for 12 hours before the blood draw. Morning appointments are ideal for consistent hormone and glucose readings. The blood draw typically takes 5–10 minutes.
Biomarkers Tested
5Bilirubin is a substance produced during the normal breakdown of red blood cells. High levels can lead to jaundice and indicate liver or bile duct problems.
A liver enzyme that helps convert proteins into energy. ALT is found primarily in the liver, making it a highly specific marker for liver damage. Elevated levels may indicate hepatitis, fatty liver disease, or medication-related liver injury.
An enzyme found in the liver, heart, and muscles. While less liver-specific than ALT, elevated AST can indicate liver damage, heart attack, or muscle injury. The AST/ALT ratio helps distinguish between different liver conditions.
An enzyme found in the liver, bones, kidneys, and digestive system. Elevated ALP can indicate bile duct obstruction, liver disease, or bone disorders. It's normally higher in children and during pregnancy due to bone growth.
A liver enzyme sensitive to alcohol use and bile duct problems. GGT is often the first liver enzyme to rise when bile ducts are blocked. Combined with ALP, it helps determine whether elevated ALP is from liver or bone.
