Fish Oil and Dietary Fiber Metabolite Profile (24-hour urine)

Why This Test Might Be Ordered

Your healthcare provider may recommend this test if they suspect issues related to how your body processes certain dietary supplements or fiber sources, such as fish oil. It could also be part of a broader evaluation for gastrointestinal or metabolic conditions.

What to Expect Before the Test

You’ll need to collect all urine for a full 24-hour period. Typically, you’ll start by emptying your bladder upon waking and then collect every urine void until you wake up the next morning. Store the urine samples in a refrigerator and bring the entire collection to your lab visit.

What Happens During the Test

The collected urine is analyzed to measure specific metabolites derived from fish oil and fiber digestion. The lab uses sensitive detection methods to identify and quantify these substances in your urine sample.

What the Results Mean

Results help determine if your body is efficiently processing fish oil and fiber. Elevated levels might indicate issues with absorption or metabolism, while normal levels suggest healthy processing. Your healthcare provider will interpret these results in the context of your overall health.
