We're launching a study to better understand childhood allergies

Your purchase of the Tiny Health Gut Test may contribute to science on the potential link between the infant (and mom) gut microbiome and the development of allergies. In partnership with Free to Feed, we intend to publish our findings when the study concludes.

Recruitment starts May 2023

For babies ages 0 to 3 months (see criteria)

More than 40% of American school-aged children have at least one chronic health condition

And we think the number is much higher when it comes to babies and toddlers. From recent research we know that there’s an association between the gut microbiome and the progression of atopic march: eczema, food allergies, asthma and allergic rhinitis[2], [3], [4].  However:

  • Even though atopic conditions are starting to become more prominent, research is still sparse.
  • Even more so when it comes to allergies like cow’s milk protein allergy and sensitivities to breastmilk.
  • Overall, more data is needed to develop further key insights, better diagnosis and potential therapeutics.

How does the Research Edition work?

Purchase the kits, sample and complete surveys

This study is only open to people who have purchased Tiny Health baby gut tests.

To further investigate the important connection between a mom and baby’s gut microbiome, we encourage that the mom also submit one gut test along with her baby’s at a discounted rate.

A stool sample can be taken directly from a soiled toilet tissue or diaper using our dry swab method.

You will fill out surveys upon sampling and towards the end of the research period, as you’ll be a part of furthering allergy research.

Processed in a CLIA-certified lab and using proprietary technology, Tiny Health’s gut test provides strain-level precision and a complete list of all microbes in the gut microbiome including bacteria, fungi, virus, parasites, and archaea. Results will take 4-5 weeks to arrive.
