Infant & Toddler Gut Health Testing
If your baby or toddler is experiencing colic, digestive discomfort, skin issues, or frequent illness, their gut health may be playing a key role.
The GI Axis Advanced test for infants and toddlers provides a detailed analysis of the gut microbiome using a simple at-home stool sample. It is specifically designed for children aged 0–3, using age-specific reference ranges to give meaningful, personalised insights.
This test helps parents understand what’s happening inside their child’s gut and how it may be affecting their development, digestion, and overall wellbeing.
What Is a Gut Microbiome Test for Babies and Toddlers?
A gut microbiome test analyses the microorganisms living in your child’s digestive system, including bacteria, fungi, viruses, and parasites. In early life, the gut microbiome is still developing and plays a critical role in:
- Immune system development
- Digestion and nutrient absorption
- Brain development and behaviour
- Inflammation and allergy response
Disruptions during this stage can contribute to symptoms such as colic, diarrhoea, skin conditions, and feeding issues.
Why Gut Health Matters in the First 3 Years
The first three years of life are the most important period for microbiome development. During this time, the immune system is being trained, gut bacteria are rapidly evolving, and external factors (diet, antibiotics, environment) have a lasting impact.
An imbalance in gut bacteria during infancy has been linked to:
- Allergies and intolerances
- Eczema and skin flare-ups
- Digestive discomfort and colic
- Long-term metabolic and immune conditions
Understanding your child’s gut early allows for targeted support during this critical window.
What Does This Test Measure?
This test provides a comprehensive microbiome and pathogen analysis, using advanced shotgun metagenomics in a UKAS-accredited laboratory.
Gut Health Markers
- Microbiome diversity (Shannon Index)
- Microbiome development stage (age-adjusted)
- Intestinal permeability (gut barrier function)
- Hydrogen-producing bacteria (linked to SIBO)
- Antibiotic resistance and degradation patterns
- 17 key bacterial species for early-life health
Pathogens & Disruptors
Screening for organisms interfering with gut balance:
- Fungi (6 types)
- Parasites (5 types)
- Pathogenic bacteria (9 types)
- Viruses (6 types)
- Archaea (2 types)
Gut–Body Connections in Early Development
The infant gut influences multiple systems in the body. This test analyses 10 key gut health axes:
- Gut–brain axis: mood, behaviour, early cognition
- Gut–skin axis: eczema, rashes
- Gut–immune system: allergies, illness frequency
- Gut–metabolism: growth and energy use
- Gut–hormone: and thyroid function
- Gut–liver: and detoxification pathways
- Gut–lung: and respiratory health
- Gut–heart: and circulation
- Gut–joint: and inflammation
- Gut–eye health
These connections help explain how gut imbalances can show up as symptoms elsewhere in the body.
What Symptoms Can This Help Investigate?
This test is particularly useful if your child experiences:
Functional Insights Provided in the Report
Beyond identifying microbes, the test analyses how your child’s gut is functioning across four key areas:
Digestive & Absorption
Macronutrient/micronutrient absorption and bowel habits.
Immune & Inflammation
Inflammation index, histamine response, and allergy pathways.
Gut Activity Markers
Short-chain fatty acid (SCFA) production and detoxification.
Behaviour & Development
Mood, focus, sleep patterns, and ADHD/ASD-related pathways.
Metabolic & Energy
Weight, calorie utilisation, and physical activity associations.
How the Test Works
The process is designed to be simple and stress-free for parents.
What Makes This Test Different?
Unlike generic tests, this is specifically for infants and toddlers (0–3), featuring:
- Age-specific reference ranges
- Microbiome development tracking
- Shotgun metagenomics DNA sequencing
- Broader pathogen screening
- Functional health insights, not just raw data
Is This Test Safe for Babies?
Yes. The test is completely non-invasive and only requires a stool sample. There are:
- No needles
- No discomfort
- No clinical visits required
Test Accuracy & What You Receive
The test uses advanced sequencing technology to analyse microbial DNA in detail. Samples are processed in a UKAS-accredited laboratory, ensuring high-quality analysis, reliable microbial detection, and consistent reporting standards.
Note: Results should be interpreted as health insights rather than medical diagnoses, ideally alongside professional guidance.
Your detailed report includes:
- Full microbiome breakdown
- Identification of imbalances or pathogens
- Functional gut health analysis
- Personalised nutrition recommendations based on age
Frequently Asked Questions
Designed specifically for infants and toddlers aged 0–3 years.
Can this help with colic?
Yes, it identifies microbial imbalances and functional markers associated with colic.
No. It provides insights, not diagnoses.
How long do results take?
Typically within 1–2 weeks after the sample reaches the lab.
