• The duodenal string test capsule is a cheap and simple device used for sampling the contents of the upper gastrointestinal tract. Its major applications in pediatrics are in diagnosis of enteric parasitic infestations, confirmation of contaminated small-bowel syndrome, diagnosis of Salmonella infection, and assessment of neonatal cholestasis. Pediatricians should be aware of this invaluable diagnostic aid.
