Specimen Required

3 g of stool from a random collection. (Specimen from timed

collection [24, 48, 72 hour] is not acceptable.) Send specimen

frozen in container (Supply T288) supplied. See "Stool Collections" in

Special Instructions.   

Note:    If collecting from an infant, use nonabsorbent diapers to

                  collect the specimen. If stool is collected in a disposable

                  diaper, the solid and liquid stool MUST be combined. The liquid

                  portion of the stool can be aspirated from the diaper using a

                  syringe or alternatively can be expressed from the diaper into a

                  cup. If a diaper has gel absorption, a cotton ball will be

                  necessary to collect the liquid portion of the stool. It is critical

                  that urine is not also mixed with the specimen. Urine will

                  interfere with the results.
