Children whose history and physical findings suggest significant bleeding from an upper GI source receive a nasogastric tube for diagnostic purposes.

Return of coffee-ground-like material or Gastroccult-positive material confirms an upper GI bleed.

Still, the false-negative rate is 16% if duodenopyloric regurgitation is absent. Therefore, a clear nasogastric aspirate alone cannot be used to rule out of a GI bleed.
