Fecal fat test

Fecal fat test is a diagnostic procedure used to determine the amount of fat in a person's feces. This test is often used to identify malabsorption or maldigestion, conditions in which the body is unable to adequately absorb nutrients from the diet.

Overview[edit | edit source]

The fecal fat test is a non-invasive procedure that involves the collection of stool samples over a period of two to three days. These samples are then analyzed in a laboratory to measure the amount of fat present. The results of this test can provide valuable information about a person's digestive health and can help to identify conditions such as pancreatic insufficiency, celiac disease, and Crohn's disease.

Procedure[edit | edit source]

The fecal fat test requires the collection of all feces produced over a 72-hour period. This is typically done at home using a special kit provided by a healthcare provider. The collected samples are then sent to a laboratory for analysis. The laboratory will measure the amount of fat in the samples, with higher levels indicating potential malabsorption or maldigestion.

Interpretation of Results[edit | edit source]

The results of a fecal fat test are typically reported in grams of fat per 24 hours. Normal results vary, but generally, adults should excrete less than 6 grams of fat per day. Higher levels may indicate a problem with the body's ability to digest and absorb fat.

Risks and Considerations[edit | edit source]

The fecal fat test is generally considered safe, with few risks associated with the procedure. However, it can be inconvenient due to the need to collect all feces over a 72-hour period. In addition, certain medications and dietary factors can affect the results of the test, so it's important to discuss these with a healthcare provider before the test.
