Shigella species detection by nucleic acid probe (stool)

This test is done to find out whether an infection caused by bacteria is present in your body. Identifying the infection early helps your doctor choose the right treatment promptly and prevents possible complications.

Your healthcare provider may order this test if you’ve had symptoms like severe diarrhea, blood in your stool, fever, or abdominal pain—especially if you’ve traveled to areas with higher risk for *Shigella* infections. It helps confirm whether a bacterial infection is the cause of your illness.

The test works by detecting signs of the bacteria or the antigens your immune system produces in response to it. A laboratory analyzes your collected sample, and the final results show whether an infection is currently active.

A small sample of your stool is collected and analyzed using a specialized probe that targets genetic material unique to *Shigella* bacteria. This method is highly sensitive and can detect even small amounts of the bacteria’s DNA.

During your visit, a trained staff member will collect a small sample, such as a throat swab, urine specimen, or stool sample, depending on the suspected infection. The collection usually takes only a few minutes and is then sent to a laboratory.

You’ll provide a fresh stool sample (typically a single collection) in a sterile container. Avoid using toilet paper or cleaning products in the sample to ensure accuracy.

The collection itself is quick and typically causes only mild, brief discomfort. Results are generally available within a few days, and your doctor will contact you to review the findings, explain what they mean, and discuss any treatment options.

The test is usually done in a lab and may take a few days to complete. Results will be reviewed by a medical professional to determine if further treatment is needed.
