Diagnostic Platform
Gateway Biome (GB Diagnostic Platform) Transforming Gut Microbiome Health Assessment

Driving the Future of Gut Health
At 32 Biosciences, we’re revolutionizing microbiome medicine with the GB diagnostic platform, empowering individuals and healthcare providers to enhance health outcomes by restoring gut microbiome function. This innovation sets a new benchmark for precision and preventive care.
The Problem
There is NO clinically useful diagnostic to measure the functional health of the gut, and therefore, provide actionable information to improve patient outcomes. In other words, there is no precise and quantitative way to measure the gut microbiome. Clinicians cannot currently determine the specific cause of an unhealthy gut, limiting their ability to effectively treat the condition or prevent related diseases.


Our Solution: GB Diagnostic Platform
The GB diagnostic platform measures the functional health of the gut microbiome, assessing its ability to support key bodily functions. Powered by advanced machine learning and mass spectrometry, it identifies critical metabolites, offering:
Quantitative Insights
Reliable markers of microbiome function with reference ranges, making this the first and only test to establish NORMAL gut microbiome functional health.
Actionable Health Scores
A composite score reflecting the health of the gut microbiome by evaluating functional metabolites known to be critical for human and gut microbiome health.
Precision Guidance
Data to personalize interventions, including dietary changes, therapeutics or science based nutritional products.
How It Works:
A Breakthrough Approach to Gut Health
Our testing method uses a validated, quantitative, targeted mass spectrometry-based stool test that measures the functional health of the gut microbiome.
Rather than simply identifying which bacteria are present, our test focuses on what truly matters—what the gut microbiome is actually doing. By measuring functional metabolites, our test assesses the complex interaction between the human body and the gut microbiome.

Validated, quantitative, targeted mass spectrometry-based stool test that measures the functional health of the gut microbiome.

Assesses the health of the complex interaction between the human body and gut microbiome by measuring functional metabolites.

Instead of measuring what bacteria are present in the gut, our test evaluates what truly matters – what the gut microbiome is actually doing.
