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

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

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

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

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.
