Chlamydia nucleic acid detection by sequence-specific probe (stool)
This test checks for the presence of genetic material from *Chlamydia trachomatis*, a common bacterial infection that can affect the reproductive organs, causing symptoms like abnormal discharge, pain during urination, or pelvic pain. It’s often used in screening for sexually transmitted infections (STIs).
["This test helps detect *Chlamydia* infection in your stool, which may indicate an infection that hasn’t caused obvious symptoms yet."]

Why This Test Might Be Ordered
Your healthcare provider may recommend this test if you have risk factors for *Chlamydia*, such as unprotected sexual contact with multiple partners, or if you’re experiencing symptoms like persistent diarrhea, abdominal pain, or unexplained weight loss. It’s also sometimes used in routine screening for STIs in certain high-risk groups.
How the Test Works
The test uses a molecular method to detect genetic material (DNA) from *Chlamydia* in your stool sample. A special probe matches the bacteria’s unique genetic sequence, confirming its presence if found. This method is highly sensitive and accurate for detecting *Chlamydia* infections.
Sample Collection and Preparation
You’ll need to provide a fresh stool sample collected in a sterile container. The sample is then processed in a lab to extract the genetic material, which is tested for the presence of *Chlamydia* DNA. No special preparation is needed, but avoid using toilet paper or cleaning products that might alter the sample.
What to Expect After the Test
Results are typically available within 24 to 72 hours. If the test is positive, your provider will guide you on next steps, which may include treatment with antibiotics. If negative, further testing or follow-up may be recommended depending on your symptoms and risk factors.

Frequently asked questions
If the test is positive, *Chlamydia* infection can lead to serious complications, including chronic pelvic pain, infertility, or increased risk of other STIs. Early treatment with antibiotics can prevent these issues and reduce the risk of spreading the infection to others.
A positive result means the test detected genetic material from *Chlamydia* in your stool, indicating an active infection. This requires medical attention to prevent complications and ensure you’re treated properly.
Yes, this test is sometimes used as a screening tool for sexually transmitted infections, especially in individuals at higher risk. Even without obvious symptoms, an infection can still be present and require treatment.
