The Right Gut Health Test for You.

The gut microbiome refers to the collection of microorganisms, including bacteria, viruses, fungi, and other microbes, that reside in the digestive tract. The majority of these microorganisms are bacteria, and they play a crucial role in maintaining our health and well-being.

The gut microbiome is incredibly diverse, consisting of trillions of microorganisms belonging to thousands of different species. While each person's gut microbiome is unique, there are some commonalities among individuals. The composition of the microbiome can vary depending on factors such as diet, lifestyle, genetics, and exposure to various environmental factors.

The gut microbiome has a wide range of functions and influences many aspects of our health. Some of its key functions include:

  1. Digestion and Nutrient Absorption: Our microbiome helps break down certain types of dietary fibers and other complex molecules that our own digestive enzymes cannot process. As a result, the microbiome produces essential nutrients, such as short-chain fatty acids, which are an important energy source for the cells lining the colon.

  2. Immune System Regulation: The gut microbiome plays a vital role in training and modulating our immune system. It helps develop immune tolerance, distinguishing between harmful pathogens and beneficial bacteria, and promoting a balanced immune response.

  3. Metabolism and Weight Regulation: There is growing evidence that the gut microbiome influences metabolism and body weight. Certain microbes can extract more energy from the diet, affecting how efficiently we absorb and store calories.

  4. Protection Against Pathogens: The gut microbiome helps protect against harmful pathogens by occupying niches in the gut and competing for resources, producing antimicrobial compounds, and promoting the growth of beneficial bacteria that can inhibit the growth of pathogens.

  5. Brain-Gut Communication: The gut microbiome has been linked to brain function and mental health. The gut and the brain communicate bidirectionally through various pathways, and alterations in the microbiome composition have been associated with conditions like anxiety, depression, and neurodevelopmental disorders.

Analyzing the gut microbiome of an individual is an important part of personalizing their healthcare. Here at the Center for Generative Medicine, we lean heavily into two test kits, GI Map, and BiomeSight for microbiome insights. The subtle differences between these kits allow for us to hone in on specific areas of interest.

The GI Map and BiomeSight kits they differ in a few key ways:

  1. Technology: The GI Map uses polymerase chain reaction (PCR) technology to identify DNA fragments of specific bacterial species and genetic markers associated with inflammation and digestion. The BiomeSight microbiome kit uses next-generation sequencing (NGS) to identify and quantify the DNA of all microbial organisms in a sample.

  2. Analysis: The GI Map provides information on the presence and abundance of specific bacteria, fungi, parasites, and viruses, as well as markers for inflammation, digestive function, and immune health. BiomeSight, on the other hand, provides a comprehensive analysis of the entire microbial community in the gut, including both known and unknown bacteria and archaea. It does not test for viruses and fungi, nor does it provide biomarkers of inflammation, which are important for many of our patients.

  3. Clinical relevance: when we’re looking to make a specific diagnosis, we’ll opt for a GI-Map as it includes a number of non-microbial parameters that can establish the identity of a gastrointestinal pathology. We’ll also lean towards this kit in the active management of gastrointestinal pathologies such as inflammatory bowel disease (Crohn’s and Ulcerative Colitis) as it gives us important biomarkers such as calprotectin to gauge inflammatory levels. A BiomeSight, on the other hand, gives us a better glimpse into how your microbiome contributes to your function as an entire system. We’ll lean more into this test when we’re interested in seeing how your gut bacteria relate to your metabolism, systemic inflammation, cognitive and psychiatric health, and longevity.
