What is this test?

A gastrointestinal pathogen panel examines stool for genetic material from specific bacteria, viruses, or parasites. The laboratory uses a nucleic acid amplification method with probes to identify possible causes of infection.

Why might I need this test?

This test may be ordered for diarrhea, abdominal cramps, fever, vomiting, or other digestive symptoms, especially when symptoms are prolonged, severe, or unexplained. It may also be used during outbreaks or when a person has a weakened immune system.

How is the test performed?

A stool sample is collected and tested in the laboratory. The laboratory checks for the genetic material of pathogens included in the panel; a positive result identifies which tested organism was detected.

How do I prepare for the test?

Follow the laboratory's stool-collection instructions carefully. The type and amount of stool required and any restrictions should be confirmed before collection, and the sample should be returned in the container provided.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Does this test require a blood sample?
No. This panel is performed on a stool sample.
Can the panel identify the exact cause of diarrhea?
It can detect and identify many common gastrointestinal pathogens that may cause diarrhea. Some symptoms can also be caused by conditions or organisms not included in the panel.
What should I do if the result is positive?
Contact your healthcare professional to review the result and determine whether treatment or additional testing is needed. Do not start antibiotics or other infection treatment unless prescribed.
