Study Notes
Liver Function Tests (LFTs)
- Elevated AST, ALT, Bilirubin, and prolonged PT suggest liver dysfunction, potentially caused by cirrhosis, hepatitis, or cholecystitis.
- Low Albumin and Fibrinogen levels may indicate liver disease or malnutrition.
Pancreatitis Indicators
- Elevated Lipase and Amylase levels strongly suggest pancreatitis.
- Low Calcium levels can occur in pancreatitis and malnutrition.
- Low platelet count can be seen with pancreatitis.
Gastrointestinal Bleeding
- Decreased Hemoglobin and Hematocrit levels are indicative of gastrointestinal bleeding.
- Low platelet levels are associated with liver dysfunction, which can result from GI bleeds.
- Elevated BUN may indicate hemoconcentration and protein absorption from blood in the GI tract.
Other Important Values
- Low white blood cell (WBC) count could be a result of infection or stress response associated with pancreatitis or a GI bleed.
- Elevated ammonia levels strongly suggest liver failure.
- Electrolyte imbalances can occur due to hemoconcentration in early GI bleed or hemorrhagic pancreatitis.
