Fecal Fat Ordering Recommendations
  


Mnemonic: FECQ FAT

Methodology: Nuclear Magnetic Resonance Spectroscopy
Performed: Sun-Sat
Reported: 2-3 days
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) to a clean, unpreserved vial (ARUP Supply # 40910). Available online through eSupply using ARUP Connect™ or contact ARUP Client Services at (800) 522-2787. Refer to instructions in Stool Collection-Timed Specimens (24, 48, 72 Hours) under Specimen Handling at www.aruplab.com.

Storage/Transport Temperature: Frozen.

Remarks: 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.
If weight and time are not provided it is assumed the collection is random and alternative testing (Fat, Fecal Qualitative, ARUP test code 0020385) can be performed.


Unacceptable Conditions: Random collections. Specimens containing barium or charcoal. Specimens in media or preservatives. Containers larger than 500 mL (500 g), such as paint cans, will be rejected and discarded. Submissions without collection time and weight information.

Stability (collection to initiation of testing): Ambient: 1 hour; Refrigerated: 4 days; Frozen: 2 weeks
Reference Interval:
0-5 years: 0.0-2.0 g/24h
6 years and older: 0.0-6.0 g/24h
Interpretive Data:
