Notes Test is not routinely performed on inpatients after 3 days of admission. New onset of diahrreal illness in such patients is most likely due to other causes, including Clostridium difficile infection.
The yield of enteric pathogens is reduced when specimens are delayed in transit to the laboratory ( > 2hrs from collection for unpreserved specimens)
