What this test reveals

expand_more

A GI Profile stool PCR test uses DNA detection to identify bacteria, parasites, and other microorganisms in your digestive tract. It provides a detailed map of your gut microbiome composition and can detect pathogens that may cause digestive symptoms or inflammation.

warning

What abnormal values may indicate

expand_more

When elevated: High levels of pathogenic bacteria or parasites indicate potential infection or dysbiosis (microbial imbalance). This may correlate with digestive symptoms, inflammation, or compromised gut barrier function. When low: Low or absent levels of beneficial bacteria suggest dysbiosis or reduced microbial diversity. This can indicate prior antibiotic use, dietary factors, or conditions affecting normal gut flora establishment.

exercise

For athletes

expand_more

Gut health directly impacts nutrient absorption, immune function, and recovery—all critical for athletic performance. Identifying dysbiosis or pathogenic organisms can explain persistent GI distress, bloating, or fatigue that undermines training quality and adaptation.
