Specimen:    1 Gram stool submitted in a sterile container.

PREFERRED Sample: A fresh stool sample must be received at the lab within one hour of collection. The sample must not be refrigerated or frozen.

Alternate sample: If a stool sample cannot be brought to the lab within one hour of collection, it can be placed in Cary-Blair transport media. Samples in Cary-Blair media, if refrigerated, are stable up to 48 hours. Cary-Blair collections instructions are listed on LabHelp in the Specimen Collection section.

If a rectal swab is submitted, the lab will be unable to perform the Shiga Toxin testing.

Do not submit more than 1 culture per day or no more than 3 consecutive days. Reported at 3 days.

Stool for fungus/yeast culture should be ordered as C YEAST.
