User Testing of the Evivo Screening Test

This is a prospective, multi-center clinical study of the Evivo Infant Gut Bifidobacterium
Screening Test ("Evivo Screening Test").

Lower levels of bifidobacteria in the infant gut have been linked to increased incidence of
metabolic and inflammatory disorders. This CLIA Waiver User Testing study is being conducted
to evaluate the performance of the Evivo Infant Gut Bifidobacterium Screening Test, which was
designed to differentiate between high and low levels of Bifidobacterium in infant stool.
This study is intended to confirm the precision of results for this screening test, as well
as its ease of use, in a setting that closely resembles the conditions of intended use,
specifically the circumstances of sample collection, the location of test sites, and the
potential operators.

Inclusion Criteria:

- Infants aged 0-6 months.

- Generally healthy infants.

Exclusion Criteria:

- Infants should not have an acute infection.

- Not intended for use with stool containing meconium.

- Infants with jaundice should not be tested until it has resolved.

- This test should not be used for infants with carbohydrate malabsorption syndrome,
which may present with one or more of the following persistent signs: abnormally
foul-smelling, mucus-containing, and/or green frothy stools.
