What's this test for?

This test is ideal if you're experiencing greasy, foul-smelling, or floating stools, unexplained weight loss, or ongoing digestive discomfort. It helps check whether your body is properly digesting and absorbing fat from food. This can be an early clue to problems with your digestive system, pancreas, or gut.

What happens after I get my results?

Your results will show up in your account with an explanation of what a normal versus abnormal fat level in your stool means. If your result suggests poor fat absorption, next steps often include reviewing your diet, cutting back on high-fat foods temporarily, and retesting to confirm the pattern. If your result is significantly abnormal or you have ongoing severe symptoms, seek medical care promptly. You can download the full lab report anytime and track any repeat testing over time using the trends feature.

What symptoms indicate I may need this test?

Common signs include greasy or oily-looking stools that float or are hard to flush, frequent loose stools, unexplained weight loss, bloating, and feeling unusually tired after meals. Some people also notice a strong, unpleasant odor to their stool. If these symptoms are ongoing, this test can help figure out if fat malabsorption is the cause.

How can I naturally support healthy fat digestion?

Eating smaller, more frequent meals can ease the workload on your digestive system. Adding digestion-friendly foods like ginger, papaya, and fiber-rich vegetables may help support healthy gut function. Staying hydrated and limiting fried or heavily processed fatty foods can also reduce symptoms while you sort out the underlying cause. These steps support digestion but do not replace addressing an underlying medical condition.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. Once processed, they will be uploaded directly to your secure online account. You'll get a notification so you can log in and review everything as soon as it's available.

Who should consider this test?

This test is a good fit for anyone with ongoing digestive symptoms like greasy stools, bloating, or unexplained weight loss. It's also useful for people who have a known digestive or pancreatic condition and want to monitor how well they're absorbing nutrients. If you've noticed a pattern of symptoms after eating fatty meals, this test can offer helpful insight.

What is fat malabsorption and why does it matter?

Fat malabsorption happens when your digestive system isn't breaking down or absorbing dietary fat properly, so it passes through undigested. This matters because fat carries important vitamins like A, D, E, and K, so ongoing malabsorption can lead to nutrient deficiencies over time. Catching it early lets you make diet changes or seek care before it affects your overall health.

What does a high fat result mean?

A high amount of fat in your stool suggests your body isn't fully digesting or absorbing the fat you eat. This can be linked to issues with the pancreas, gallbladder, or small intestine. It's worth noting how your symptoms line up with your diet and considering a follow-up test to confirm the finding.

What causes abnormal fecal fat levels?

Common causes include pancreatic issues that limit digestive enzymes, gallbladder or liver conditions that affect bile production, and intestinal conditions that interfere with nutrient absorption. Certain medications, like those containing mineral or castor oil, can also cause a false abnormal result. Diet extremes, such as a very high-fat meal before testing, can sometimes skew results too.

What should I do if my results are abnormal?

Start by reviewing the pre-collection guidance to rule out anything that might have skewed the result, like oil-based products or supplements. Consider adjusting your diet to reduce fat intake temporarily and watch whether your symptoms improve. If symptoms are severe, persistent, or worsening, seek medical care so the underlying cause can be properly addressed.
