Enzyme primarily found in liver. More specific for hepatocellular injury than AST. Key marker for liver disease.
Learn MoreALP (Alkaline Phosphatase)
Normal: 30-120 IU/L
Enzyme found in liver, bone, intestine, and placenta. Elevated in cholestatic disorders and bone disease.
Learn MoreBilirubin (Total & Direct)
Total: 0.2-1.2 mg/dL

Major protein synthesized by liver. Low levels indicate chronic liver disease or malnutrition. Marker of synthetic function.
Learn MoreTotal Protein
Normal: 6.0-8.3 g/dL
Sum of albumin and globulins. Assesses overall protein status and liver synthetic function.
Learn MoreGGT (Gamma-Glutamyl Transferase)
Normal: 0-50 IU/L
