Liver Function Panel

The Liver Function Panel evaluates key enzymes and proteins that reflect liver health and overall metabolic function. This panel helps assess liver cell integrity, bile flow, and the liver’s ability to produce essential proteins.

This panel includes assessment of:

• Alanine Aminotransferase (ALT)
• Aspartate Aminotransferase (AST)
• Alkaline Phosphatase (ALP)
• Total and Direct Bilirubin
• Albumin
• Total Protein

Testing a Liver Function Panel helps assess:

• Liver inflammation or injury
• Fatty liver disease
• Hepatitis screening
• Bile duct obstruction
• Liver synthetic (protein-producing) function
• Monitoring medication effects on the liver

Reference Ranges (Adult)
Ranges vary slightly by laboratory, but typically include:

ALT: ~7–45 U/L
AST: ~8–43 U/L
Alkaline Phosphatase: ~35–104 U/L
Total Bilirubin: ~0.0–1.2 mg/dL
Albumin: ~3.5–5.0 g/dL
Total Protein: ~6.3–7.9 g/dL

What Your Results May Mean

• Elevated ALT/AST: May indicate liver inflammation or cell injury.
• Elevated ALP or Bilirubin: May suggest bile flow obstruction or liver dysfunction.
• Low Albumin or Total Protein: May reflect impaired liver synthetic function or nutritional issues.
• Within normal range: Suggests healthy liver enzyme levels and protein production.
