72 Hour Fecal Fat: Reference Range

72 Hour Fecal Fat Test measures the fat level in the stool, to diagnose malabsorption. In order to get tested, you may consume 50 to 150 grams of fat a day for 2-3 days before and during the stool sample collection.

Reference Range:

A healthy person’s stool should contain 2 to 7 grams over 24 hours, and 6 to 21 grams over 72 hours in such conditions.

What Does the Result Mean?

Positive: A positive result indicates that the fat may not be well absorbed; you may have malabsorption.

Negative: Normally, the result should be negative. But a negative result does not ensure the absence of malabsorption. A follow-up quantitative test may be needed.
