| Specimen Required: |
Collect: 24-, 48- or 72-hour stool collection. Refrigerate during collection.
Specimen Preparation: Weigh entire collection. Homogenize entire collection (using a graduated cylinder, add sufficient water to give milk shake consistency) and aliquot 20 mL (20 g) into a clean, unpreserved vial (ARUP supply # 40910). Provide weight of entire collection, volume of water added for homogenization (if applicable), and duration of collection. Complete information is required in order to perform accurate calculations. Refer to instructions in Stool Collection-Timed Specimens (24, 48, 72 Hours) in the Laboratory Test Directory.
Storage/Transport Temperature: 20 mL (20 g) homogenized aliquot, frozen.
Remarks: If weight and time are not provided it is assumed the collection is random and alternative testing (Fat, Fecal Qualitative - 0020385) can be performed.
Unacceptable Conditions: Specimens containing barium, charcoal, specimens in media or preservatives. Containers larger than 500 mL (500 g), such as paint cans, will be rejected and discarded. Random collections. Submissions without collection time and weight information.
Stability (collection to initiation of testing): Ambient: 1 hour; Refrigerated: 96 hours; Frozen: 2 weeks
