Comprehensive Stool Tests - Need some answers for what may be going on inside?


Emerging microbiome research has shown the importance of gut health to our overall health. Research studies link up to 80% of our immune system to the gut. So, taking steps to improve gut health supports lifelong wellness.

There are many tools and strategies to help improve your gut health. These include eating nutrient dense foods (yes, difficult for many children), taking supplements for gut health, and working with a practitioner who understands how to help children improve their gut health. Yet there is no one-size-fits-all approach to gut health. For example, taking a probiotic for the gut may be beneficial for some individuals. In others, it could do more harm than good. Imagine there’s already high levels of a beneficial microbe in your gut. Taking a probiotic could boost those levels to a point where they are too high, resulting in low diversity in the gut microbiome.

Taking a gut microbiome test is the best way to determine if there are any imbalances in your child's gut that need course correction. Testing helps educate you on the best actions for your child's unique microbiome. 

Comprehensive Stool Tests 

(Choose one below) 

An at-home Comprehensive Stool Test measures key markers of digestion, absorption, and intestinal function, including markers for gut bacteria, yeast, GI pathogens, and parasites. Learning about your child's markers will help to determine the underlying cause(s) of his constipation so we can improve digestion, absorption and elimination and relieve constipation long term. 

Below find stool test options recommended by CRaP4Kids, depending where in the world you reside.

Tiny Health Stool Tests

Tiny Health has created stool tests using shotgun metagenomics analysis for those 0 to 100 years old.  

Available in Canada and the USA.  They have two tests to choose from: their PRO test and their gut microbiome test.

The Details ...

Deep shot-gun metagenomics sequencing is the gold standard to get a comprehensive analysis that is reliable when trying to make informed decisions to overcome bowel issues and heal the gut. 

Compared with conventional diagnostic methods, metagenomic sequencing is more sensitive and better in detecting novel, rare, and unexpected pathogens. Shotgun metagenomic sequencing allows researchers to comprehensively sample all genes in all organisms present in a given complex sample. The method enables microbiologists to evaluate bacterial diversity and detect the abundance of microbes in various environments.1

Unlike most of the other standard comprehensive stool tests which use older and less reliable testing methodologies (e.g., culture, qPCR, 16S), both Tiny Health and BiomeFX use the shotgun metagenomics method.  


 Stool tests are not intended to diagnose, treat, cure or prevent any disease. Always consult with your professional health care provider if you are taking any medication.
