Specimen Collection - Enteric Transport Container (Green Cap / Red Fluid):
The patient must not be taking any form of medication unless specifically permitted by the physician. The use of barium and bismuth with certain radiological examinations is particularly damaging to the specimen. Collection should be at least one week after usage.
Samples from multiple stool specimens are recommended to assure optimum recovery of enteric pathogens. Three consecutive specimens should be obtained during the acute stage. To identify chronic, subclinical, and carrier states, collection of stool specimens on three consecutive days is recommended.
Specimen Collection - SAF vial (Yellow Cap / Clear Fluid)
The patient should be cautioned against the use of antacids, barium, bismuth, antidiarrheal medication, or oily laxatives prior to collection of the specimen. Specimens should be delayed five to ten days after barium and at least two weeks after antibiotics are administered.
To assure recovery of parasitic elements, which are passed intermittently and in fluctuating numbers, three specimens spaced a few days apart must be examined.
