What's this test for?

This test is ideal if you're experiencing persistent watery diarrhea, stomach cramps, or fever after taking antibiotics. C. difficile is a bacteria that can overgrow in your gut once antibiotics wipe out your normal gut flora, leading to colitis. This test checks whether that bacteria and its toxins are the cause of your symptoms.

What happens after I get my results?

Your results will show up in your account along with an explanation of what a positive or negative result means. If your result is positive, next steps usually include stopping the antibiotic that triggered the problem (if possible) and starting targeted treatment, along with staying hydrated and eating easy-to-digest foods. The full lab report is downloadable from your account, and if you're retested later you can track your results over time using the trends feature. If you have severe diarrhea, high fever, or signs of dehydration, seek medical care right away.

What symptoms indicate I may need this test?

Watch for watery diarrhea that happens three or more times a day, stomach pain or cramping, low-grade fever, and nausea, especially if these symptoms start during or shortly after a course of antibiotics. Loss of appetite and general fatigue are also common. If symptoms are severe or don't improve after a few days, this test can help identify the cause quickly.

How can I naturally support gut health during recovery?

Eating probiotic-rich foods like yogurt or kefir can help restore healthy bacteria in your gut once the infection clears. Staying well hydrated with water and electrolyte drinks helps replace fluids lost from diarrhea. Avoiding greasy, spicy, or high-fiber foods temporarily can ease digestive strain while your gut heals, and getting extra rest supports your body's natural recovery process.

When will I get my results?

Results are typically ready within about 7 days after your sample is processed at the lab. Because this test may include a culture step followed by a reflex toxin PCR if needed, turnaround can vary slightly depending on what additional testing is triggered. You'll be notified as soon as your results are available in your account.

Who should consider this test?

Anyone who has recently taken antibiotics and developed new diarrhea or stomach cramps should consider this test. It's especially useful for people who've been hospitalized, live in long-term care facilities, or have had C. difficile infections before, since these groups are at higher risk. It's also helpful if a first round of treatment didn't clear up symptoms.

What is C. difficile and why does it matter?

C. difficile is a type of bacteria that can grow out of control in your intestines, usually after antibiotics disturb your normal gut bacteria. It produces toxins that damage the lining of your gut, causing diarrhea and inflammation known as colitis. Catching it early matters because untreated infections can become severe and, in rare cases, dangerous.

What causes a positive C. difficile result?

A positive result usually means the bacteria has overgrown in your gut, most often triggered by recent antibiotic use, especially broad-spectrum antibiotics. Other risk factors include a hospital stay, older age, a weakened immune system, or previous C. difficile infections. Close contact with someone who has an active infection can also spread the bacteria.

How often should I retest?

If you're treated for a confirmed infection, retesting is usually recommended only if symptoms return or don't improve within a week or two of finishing treatment. Testing too soon after treatment can give a false positive since the bacteria's genetic material may still be detectable even after the infection clears. Your results report will note if a retest makes sense for your situation.

What should I do if my results are abnormal?

If your result comes back positive, focus on staying hydrated, resting, and following any pre-collection or follow-up instructions provided with your report. Avoid taking anti-diarrheal medications unless advised, since they can sometimes make the infection worse by keeping toxins in your gut longer. If symptoms are severe, such as high fever, blood in your stool, or intense abdominal pain, seek medical care right away.
