Simple tests for small intestinal function help diagnose malabsorption syndromes and guide further testing. Key procedures include fecal analysis, D-xylose, and breath hydrogen tests for efficient diagnosis.

Area of Science:

  • Gastroenterology
  • Diagnostic Medicine
  • Biochemistry

Context:

  • Small intestinal function tests are crucial for diagnosing malabsorption syndromes.
  • These tests provide initial differential diagnostic information.
  • They enable a more rational and restricted use of invasive procedures.

Purpose:

  • To outline essential diagnostic procedures for evaluating small intestinal function.
  • To highlight the role of simple tests in identifying malabsorption.
  • To guide the selection of further diagnostic techniques.

Summary:

  • Analysis of fecal wet weight and fat excretion.
  • D-xylose and breath-hydrogen tests (lactose/glucose substrates).
  • Detection of bile acid malabsorption (75Se-HCAT) and protein-losing enteropathies (alpha-1-antitrypsin clearance).

Impact:

  • Facilitates early and accurate diagnosis of malabsorption.
  • Reduces the need for unnecessary invasive procedures.
  • Improves patient management through targeted interventions.
