Chlamydia trachomatis Nucleic Acid Detection by Probe-Based Assay (Stool)
This test checks for the presence of genetic material from *Chlamydia trachomatis*, a common bacterial infection that can affect the reproductive system, throat, or eyes. It uses a stool sample to detect the infection, often done if symptoms like diarrhea, abdominal pain, or unexplained fever are present.

This test helps your healthcare provider check for a specific health condition by measuring certain markers in your body. The results can support a diagnosis, guide treatment decisions, or help monitor how well a current treatment is working for you.
Your healthcare provider may recommend this test if you have symptoms like persistent diarrhea, unexplained abdominal pain, or fever—especially if you’ve recently traveled to areas with higher infection rates or have been exposed to someone with a gastrointestinal infection. It’s also used in research or specialized diagnostic settings where stool-based testing is preferred.
The test analyzes a small sample taken from your body using laboratory methods that detect or measure specific substances. Trained laboratory professionals process the sample, and the measurements are compared with established reference ranges to help interpret your results.
The test detects genetic material (nucleic acids) from *Chlamydia trachomatis* using a specialized probe in your stool sample. If the bacteria are present, the probe binds to their genetic material, confirming infection. This method is highly sensitive and doesn’t rely on growing the bacteria in a lab.
A trained healthcare professional will collect your sample, usually during a quick visit. Depending on the type of test, the sample may be a small amount of blood, urine, or a swab from a specific area. The collection process is generally fast, and most people find it only mildly uncomfortable, if at all.
A stool sample is collected, usually via a simple rectal swab or stool collection kit provided by your provider. The sample is then sent to a lab for processing. You may need to follow specific instructions to ensure the sample is fresh and representative.
After your sample is collected, it is sent to a laboratory for analysis, and results are typically available within a few days, though timing can vary. Your healthcare provider will contact you to discuss the results, explain what they mean, and outline any next steps, such as additional testing or treatment, if needed.
Results are typically available within 24–72 hours. If the test is positive, you’ll likely need antibiotics to treat the infection. Follow-up testing may be recommended to confirm treatment success or monitor for recurrence.

Frequently asked questions
If the test is positive, you may have an infection that requires treatment to prevent complications like chronic diarrhea, intestinal inflammation, or, in rare cases, long-term gastrointestinal issues. Early detection helps manage symptoms and reduces transmission risk to others.
A positive result indicates the presence of *Chlamydia trachomatis* genetic material in your stool, suggesting an active infection. This does not always mean you have symptoms, so even if you feel well, treatment may still be necessary to prevent complications or spread the infection.
Yes, you can eat and drink normally before the test unless your provider gives specific instructions. Avoid using laxatives or stool softeners unless directed, as they may alter the sample.
