Chlamydia nucleic acid test by nucleic acid amplification (specimen: stool)

Why This Test Is Done

Your healthcare provider may recommend this test if you have symptoms like persistent diarrhea, abdominal pain, fever, or unexplained weight loss—especially if you’ve had recent contact with someone infected. It’s also used in screening for chlamydia in stool samples, particularly in patients with suspected gastrointestinal chlamydia (e.g., after travel, exposure to contaminated water, or certain medical conditions).

How the Test Works

The test uses a specialized lab technique to identify genetic material (nucleic acids) from *Chlamydia* in your stool. This process is highly sensitive and can detect even small amounts of the bacteria’s DNA or RNA, helping confirm an infection before symptoms appear.

Sample Collection and Preparation

A stool sample is collected in a sterile container, typically during a routine bowel movement. The sample is then sent to a lab where it’s processed to extract genetic material for testing. No special preparation is needed, but avoid using laxatives or enemas before collection if instructed.

What to Expect After Testing

Results are usually available within 24–72 hours. If positive, follow-up care (e.g., antibiotics) will be recommended by your provider. If negative but symptoms persist, further testing or evaluation may be needed to rule out other causes.
