Question 1

How long does it take to get results from a GI pathogen panel?

Accepted Answer

Results are typically available in about an hour to a few hours from the time the laboratory receives your sample, though total turnaround time including shipping is usually 1-3 business days. Results of a GI pathogen panel may be available within a few hours, compared to a few days with some traditional testing. This rapid turnaround time is significantly faster than traditional stool culture methods, which can take 3-5 days or longer to provide results.

Question 2

What should I do if multiple pathogens are detected in my results?

Accepted Answer

Studies have found multiple pathogens in 16.4% of samples using modern GI panels versus 1% with conventional testing. Among samples with multiple pathogens, 84% were positive for EAEC or EPEC. The detection of multiple organisms does not necessarily mean all are causing your symptoms, as some people can carry certain pathogens without being ill. It's important to discuss these results with a healthcare provider who can interpret them in the context of your symptoms and medical history to determine which organisms may be clinically significant and require treatment.

Question 3

Can this test detect antibiotic resistance in bacteria?

Accepted Answer

The standard GI pathogen panel detects the presence of specific bacterial, viral, and parasitic organisms but does not typically test for antibiotic resistance genes. If a bacterial pathogen is detected and antibiotic treatment is being considered, your healthcare provider may order additional testing such as bacterial culture with susceptibility testing to determine which antibiotics would be most effective. Some laboratories may offer expanded panels that include certain resistance markers, but this would need to be specifically requested.

Question 4

Why might my doctor recommend this test over traditional stool culture?

Accepted Answer

Rapid multiplex panel detection of the most common agents of bacterial, viral, and parasitic enteric infections directly from stool specimens is sensitive, specific, and provides same-day results, obviating the need for culture, antigen testing, microscopy, or individual nucleic acid amplification tests. Traditional stool cultures can miss viral and parasitic infections entirely, while this panel detects all three types of pathogens simultaneously. The comprehensive nature and rapid results make it particularly valuable for patients with severe symptoms or those at higher risk for complications.

Question 5

What happens if I have symptoms but all test results are negative?

Accepted Answer

A negative result should not rule out infection in patients with a high pretest probability for gastrointestinal infection. The assay does not test for all potential infectious agents of diarrheal disease. Positive results do not distinguish between a viable or replicating organism and the presence of a nonviable organism or nucleic acid, nor do they exclude the potential for coinfection by organisms not contained within the panel. Your healthcare provider may consider additional testing for less common pathogens, non-infectious causes of your symptoms, or may recommend supportive care while monitoring your condition. Some gastrointestinal symptoms may be caused by factors other than infections, such as inflammatory bowel disease, food intolerances, or medication side effects.
