What baseline laboratory tests are typically included in the initial workup of chronic enteropathy?

• A. Urinalysis, hepatic function tests, and bone marrow biopsy.
• B. Liver enzymes, kidney ultrasound, and fecal culture.
• C. CBC, chemistry panel, serum albumin, cobalamin and folate, and fecal analysis.
• D. Serum vitamin D, calcium, and thyroid hormones.

Answer: (C)

When a chronic enteropathy is being evaluated, you want a set of tests that quickly reveals how the condition is affecting nutrition, inflammation, and gut absorption without jumping to invasive or imaging studies. The best initial lab panel combines a complete blood count, a chemistry panel, assessment of serum albumin, measurement of cobalamin (B12) and folate, and fecal analysis.

The CBC gives clues about systemic involvement: anemia can point to chronic blood loss or inflammation, while white cell patterns and platelet trends can hint at inflammatory or infectious processes. The chemistry panel rounds out the picture by checking electrolytes, kidney and liver function, and overall protein status; it helps detect dehydration, organ involvement, and metabolic disturbances that often accompany chronic GI disease. Serum albumin is particularly important because low levels can indicate protein-losing enteropathy or malnutrition, carrying prognostic and therapeutic significance.

Cobalamin and folate testing provides targeted information about where the GI tract is failing to absorb nutrients. Low B12 often suggests disease in the distal small intestine or pancreatic insufficiency, whereas folate status can reflect proximal small intestine function or bacterial overgrowth. Together, they help classify the disease and guide supplementation and further testing.

Fecal analysis is essential to screen for parasites, infectious organisms, and signs of fat malabsorption, all of which can drive or mimic chronic enteropathy and change management.

The other options mix tests that aren’t routinely needed at the very start of evaluation—bone marrow biopsy, imaging-based assessments, or hormone panels—unless there are specific clues that point to those issues. The combination above stays focused on the practical, informative baseline needed to guide initial diagnosis and treatment.
