What's this test for?

This test is ideal if you're experiencing persistent watery diarrhea, stomach cramps, or fever, especially after taking antibiotics. It helps identify whether a bacteria called C. difficile is causing your digestive symptoms. This is especially useful if you've recently been in a hospital or on antibiotics and your gut symptoms haven't improved.

What happens after I get my results?

Your results will show up in your account along with a plain-language explanation of what a positive or negative result means. If your result is positive, next steps usually involve starting targeted treatment quickly, staying hydrated, and avoiding foods that worsen diarrhea, and if symptoms are severe like high fever or blood in your stool, seek medical care right away. A standard lab report is available to download from your account anytime. You can also use the trends feature to track your recovery over time if you retest later.

What symptoms indicate I may need this test?

Watch for watery diarrhea that happens three or more times a day, stomach cramping, low-grade fever, and nausea, particularly if these symptoms started during or shortly after a course of antibiotics. Loss of appetite and general fatigue can also show up alongside gut symptoms. If diarrhea lasts more than a couple of days or gets worse, this test can help pinpoint the cause.

How can I naturally support gut health during recovery?

Staying well hydrated with water and electrolyte drinks is one of the most important things you can do while your gut recovers. Eating bland, easy-to-digest foods like rice, bananas, and toast can help calm irritation, while probiotic-rich foods like yogurt may support healthy gut bacteria once acute symptoms ease. Avoid dairy, caffeine, and greasy foods until your digestion settles down.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. Once processed, they're posted directly to your secure online account so you can view and download them as soon as they're available.

Who should consider this test?

Anyone with ongoing diarrhea after a recent course of antibiotics, especially broad-spectrum ones, should consider this test. It's also a good option for people who've been hospitalized or in long-term care facilities recently, since C. difficile spreads easily in those settings. Older adults and anyone with a weakened immune system are at higher risk and may want to test sooner rather than later.

What is C. difficile and why does it matter?

C. difficile is a type of bacteria that can overgrow in your gut after antibiotics wipe out your normal healthy bacteria. Once it takes over, it releases toxins, like Toxin B, that damage the lining of your intestines and cause diarrhea and inflammation. Catching it early matters because untreated infections can lead to more serious complications like severe colon inflammation.

What does a positive result mean?

A positive result means the toxin-producing genetic material from C. difficile was found in your sample, confirming it's likely the cause of your symptoms. This usually calls for prompt treatment to stop the infection and prevent it from spreading to others. Practicing good hand hygiene with soap and water is also important since alcohol-based sanitizers don't kill C. difficile spores effectively.

How often should I retest?

Retesting isn't usually needed once symptoms have resolved, since the test can stay positive for a while even after treatment works. If your diarrhea comes back within a few weeks after finishing treatment, that's a good time to retest, since C. difficile infections can sometimes return. Talk through timing with whoever is managing your treatment plan if symptoms persist.

What should I do if my results are abnormal?

If your result is positive, focus on staying hydrated, resting, and following any treatment guidance provided with your results. Isolate as much as possible from others in your household and wash your hands frequently to avoid spreading the infection. If you develop severe abdominal pain, high fever, or blood in your stool, seek medical care immediately.
