Our global life sciences company brings diagnostic testing & drug development together.
Neutral and total fats
2 - 6 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Stool (fresh random)
Approximately 3 g
0.5 g (Note: This volume does not allow for repeat testing.)
Plastic screw-cap vial
Do not contaminate outside of container; do not overfill container.
Refrigerate at 2°C to 8°C.
Patient should be on a diet containing at least 60 g of fat. The patient should not use suppositories or mineral oil before the specimen is collected. Oily material (eg, creams, lubricants, etc) should be avoided prior to collection of the specimen.
Specimen contaminated with urine and/or water; specimen on outside of container; specimen containing interfering substances (eg, castor oil, bismuth, Metamucil®, barium)
Detect the presence of fecal fatty acids and neutral fat. Increases in neutral fat are commonly associated with pancreatic exocrine insufficiency. Increase in stool total fats (neutral fats, soaps, and fatty acids) is likely to be associated with small bowel disease.
This test was developed and its performance characteristics determined by LabCorp. It has not been cleared or approved by the Food and Drug Administration.
Microscopic examination following staining with Oil Red O
• Total fats (neutral fats, soaps, and fatty acids): Normal (<100 droplets/hpf)
• Neutral fats: Normal (<60 droplets/hpf)
