The GI360 Microbiome Profile is a gut microbiota DNA analysis tool that identifies and characterizes the abundance and diversity of more than 45 targeted analytes that peer-reviewed research has shown to contribute to dysbiosis and other chronic disease states.

The Dysbiosis Index (DI) is a calculation with scores from 1 to 5 based on the overall bacterial abundance and profile within the patient's sample as compared to a reference population. Values above 2 indicate a microbiota profile that differs from the defined normobiotic reference population (i.e., dysbiosis). The higher the DI above 2, the more the sample is considered to deviate from normobiosis.

Available as x1 day collection only.

Specimen requirements:

Stool

1 day collection

Average processing time:

21 days

Available add-ons:

Zonulin add on for GI360

Age Considerations:

The GI360 Microbiome test may best be served for those ages 2 and above due to variations in the microbiome in ages 0-2.
