72 Hour Fecal Fat

Spread the love

72 Hour Fecal Fat, also called fecal fat, measures the amount of fat in a stool sample. Excess fecal fat (termed steatorrhea) may be an indication that a person’s digestive system is not working properly and/or that the individual has a condition affecting the digestion of food and absorption of nutrients (malabsorption).

The normal range for fecal fat testing is 2 to 7 grams over a 24-hour period.

A positive qualitative fecal fat test or an increased amount of fat in a 72-hour quantitative fecal fat test indicates that fat is likely not being absorbed normally.

A negative qualitative fecal fat test does not necessarily rule out malabsorption, so it may be followed up with a quantitative test.

In a 72-hour fecal fat test, a low level of fecal fat generally indicates that the person tested is digesting and absorbing fats normally and suggests that the symptoms being experienced are likely due to another cause.
