Why is this test done?

Your healthcare provider may recommend this test if you have symptoms like persistent diarrhea, abdominal pain, or unexplained weight loss, especially if you’ve traveled to regions where *Strongyloides* infections are common. It may also be used in people with weakened immune systems, such as those with HIV/AIDS or undergoing chemotherapy, to detect early signs of infection.

What does the test involve?

A sample of your stool is collected in a clean container and sent to a lab. The lab grows the parasite in a controlled environment to identify its presence, including checking for antibiotic resistance patterns.

How long does it take to get results?

Results can take several days to a week or longer, depending on the lab’s processing time and whether the parasite is present. Your provider will discuss the findings with you once they’re ready.

What are the risks or side effects?

There are generally no risks associated with stool collection. However, if you experience mild discomfort or irritation during the sample collection, inform your provider.

Frequently asked questions

How often should I get this test?
This test is typically ordered as needed based on symptoms, risk factors (e.g., travel history, immune status), or clinical suspicion. Your provider will determine the best timing for retesting if needed.
What if the test comes back positive?
A positive result means you have an active *Strongyloides* infection. Your provider will work with you to develop a treatment plan, which may include medications to kill the parasites and possibly supportive care to manage symptoms.
Can I take antibiotics before the test?
Avoid taking antibiotics or antiparasitic medications for at least 2–4 weeks before testing, as they may interfere with the accuracy of the culture results. Always follow your provider’s instructions.
