What does the GI panel include?

• A. Folate, cobalamin, TLI, PLI
• B. Glucose, fructose, lactate
• C. Urea, creatinine, electrolytes
• D. Liver enzymes only

Answer: (A)

A GI panel is designed to evaluate how the gut absorbs nutrients and how the pancreas is functioning in GI disease. Folate and cobalamin (B12) reflect intestinal absorption at different parts of the small intestine, so abnormalities point to issues in those regions or bacterial overgrowth. Trypsin-like immunoreactivity (TLI) measures pancreatic enzyme output and helps assess exocrine pancreatic function, while pancreatic lipase immunoreactivity (PLI) specifically detects pancreatic inflammation or pancreatitis. Together, these tests cover the key aspects of GI tract function that are most relevant to GI disorders: nutrient absorption and pancreatic health. Other options don’t fit as well because they assess different systems or aspects not central to a GI-focused panel. Glucose, fructose, and lactate are general metabolic or transport-related tests rather than a targeted GI panel. Urea, creatinine, and electrolytes focus on kidney function and fluid balance, not GI absorption or pancreatic status. Liver enzymes look at liver injury, which is a separate area from the GI panel’s purpose.
