    • Purpose:
      • Check liver function.
      • Monitor treatment effectiveness for severe liver disease (e.g., cirrhosis).
      • Evaluate ammonia levels in individuals receiving total parenteral nutrition.
    • Interfering Factors:

      • High-protein or low-protein diets.
      • Drugs that increase blood ammonia (e.g., loop diuretics, narcotics, thiazides, alcohol).
      • Drugs that decrease blood ammonia (e.g., broad-spectrum antibiotics, levodopa, potassium salts).
      • Strenuous exercise before the test.
    • Results and Significance:
      • Lower: Indicates essential or malignant hypertension.
      • Higher: Indicates liver disease (cirrhosis or hepatitis), Reye syndrome, heart failure, kidney failure, and severe bleeding from the stomach or intestines.

    Amylase (AMY)

    • Normal Range:
      • Serum Amylase: 25-125 IU/L
      • Urine Amylase: 1-17 IU/L
    • Amylase is an enzyme primarily produced by the pancreas and salivary glands.
    • It breaks down starch into sugars.
