About the Test

What is the GI360 Profile Test?

The GI360 Profile Test from Doctor's Data provides a comprehensive and innovative analysis of the microbiome's abundance and diversity. The test identifies and characterizes the diversity and abundance of more than 45 analytes. Specifically, the GI360 analyses the presence of pathogenic bacteria, viruses, and parasites. It also test for digestion, absorption, and inflammatory markers.

Which Patients is The GI-360 Best Used For?

An imbalance of the gut microbiota may lead to gastrointestinal conditions such as irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and other systemic conditions such as celiac disease, cardiovascular disease, neurological disorders, malnutrition, skin conditions, autoimmune disorders, immune system imbalances, and multiple inflammatory disorders. If your patient suffers from any of these conditions, the GI360 could be beneficial in narrowing down the culprit.

Other reasons physicians commonly order the GI360 test is to profile specific pathogens linked to joint pain, mucosal barrier dysfunction, autoimmune disease, food sensitivities, abdominal pain, acute or chronic diarrhea, IVD, IBS, nutritional deficiencies, bloody stool, fever, and vomiting.

What Does GI360 Test Measure?

Using a combination of multiplex PCR, MALDI-TOF, and microscopy, the GI-360 test detects and assesses the status of pathogens, viruses, parasites, and bacteria that may be leading to gastrointestinal symptoms and disease.

The GI360 test informs the Dysbiosis Index (DI) of the analyzed sample. The DI represents a calculation (with scores from 1 to 5) based on the average bacterial abundance and profile within the patient's sample compared to a reference population.

Test results are reported as -3 to +3 standard deviation from the normobiotic reference. The higher the DI is, the higher the deviation. Values >2 may indicate a microbiota composition shifted from the normobiosis reference.

What Type of Sample is Needed to Complete the GI360 test?

A 3-day at-home stool sample is required for the GI360 test.

The stool specimens for the test must be collected on three separate days. It is preferable to collect on consecutive days, although this is not mandatory. However, the final collection must be made within seven days from the first collection.

PCR testing is a highly sensitive methodology that allows the detection of very low numbers of pathogens, although it does not distinguish between live or dead pathogens. Therefore, the test should not be repeated sooner than three weeks after the completion of treatment to avoid false positives.

About the Test

The GI360™ provides a comprehensive analysis of pathogens, viruses, parasites, and bacteria in the gastrointestinal system. Analysis is performed by a combination of multiplex PCR, MALDI-TOF, and microscopy.
