What does a clinical nutritionist treat?

Renae Cinanni treats gut health and IBS, thyroid conditions including hypothyroidism and Hashimoto's, PCOS, perimenopause, hormonal imbalances, food intolerances, fatigue, and children's gut health using a root cause clinical approach.

Do I need a referral to see a clinical nutritionist in Perth?

No referral is needed. You can book directly online at Perth Nutrition & Natural Health Clinic. Existing blood test results are helpful but not required.

Are online nutrition consultations available across Australia?

Yes. Online consultations are available for clients across Australia. GI Map stool test kits can be posted directly to you and completed at home.

What is a GI Map test?

The GI Map is a DNA-based stool analysis assessing gut microbiome balance, pathogens, digestive function, gut inflammation, and intestinal permeability. It is the most requested test at Perth Nutrition & Natural Health Clinic for identifying the root cause of digestive symptoms.

Where is Perth Nutrition & Natural Health Clinic located?

The clinic is located in Perth, Western Australia, accessible for clients in Cockburn, Treeby, Piara Waters, Canning Vale, Harrisdale, Southern River, and Murdoch. Online consultations are available nationwide.

Gut microbiome test for children in Perth and Online Australia

Age-appropriate gut microbiome testing for children from birth to 17 years. The NutriPATH Baby Biome and Paediatric Biome tests use reference ranges specifically calibrated for children's developing microbiomes, so the findings are clinically meaningful for your child's stage of development.

The adult GI Map was not designed for children

The adult GI Map is the most comprehensive gut health test available for adults, and it is used extensively in clinical practice with excellent results. However, it uses adult reference ranges, and comparing a child's or infant's gut microbiome against adult benchmarks produces findings that are not clinically meaningful for a developing paediatric microbiome.

Children's gut microbiomes are dynamic and undergo significant changes from birth through adolescence, shaped by birth type, feeding method, antibiotic exposure, solid food introduction, and immune system development. What is a healthy microbiome composition for a two-year-old looks very different from what is healthy in a 35-year-old, and the reference ranges used to interpret results need to reflect that.

NutriPATH's Baby Biome and Paediatric Biome tests are calibrated specifically for children at different developmental stages, which means the clinical findings are genuinely actionable rather than misinterpreted against adult norms.

Conditions paediatric microbiome tests are commonly indicated for

Paediatric gut microbiome testing is clinically indicated for a wide range of childhood presentations where gut dysfunction is suspected as a contributing or underlying factor.

SKIN CONDITIONS

Eczema, Atopic Dermatitis & Urticaria

If your child constantly experiences skin flares despite topical steroids, then looking into the gut microbiome may be the missing link.

Gut microbiome imbalance and intestinal permeability (leaky gut) are consistently linked to childhood eczema severity. The gut-skin axis often explains why topical treatments provide only temporary relief.

DIGESTIVE SYMPTOMS

IBS, Bloating & Chronic Gut Symptoms

Does your child frequently complain of tummy aches, bloating, constipation, diarrhoea, or irregular bowel habits?

Persistent symptoms despite dietary changes may indicate an underlying gut imbalance requiring further investigation.

FOOD REACTIONS & ALLERGIES

Food Allergies & Intolerances

Does your child experience multiple or worsening food reactions, even after avoiding trigger foods?

Sometimes rather than the foods themselves, increased intestinal permeability ("leaky gut") and histamine producing bacteria may be driving ongoing immune sensitisation and the development of additional food sensitivities.

IMMUNITY

Eczema, Atopic Dermatitis & Urticaria

Does your child seem to catch every bug going around?

Frequent colds, ear infections, tonsillitis, or respiratory illnesses may indicate poor gut immune function. Around 70% of the immune system resides in the gut, making gut health essential for immunity.

POOR GROWTH & APPETITE

IBS, Bloating & Chronic Gut Symptoms

Is your child a picky eater, struggling with a poor appetite, or not growing as expected?

Food aversions, slow growth, or poor weight gain may reflect gut inflammation or nutrient malabsorption affecting healthy growth and development.

NEURODEVELOPMENT

Food Allergies & Intolerances

Does your child have behavioural concerns or mood changes alongside digestive symptoms?

The gut and brain communicate constantly, and growing research links gut microbiome imbalances with behaviour, mood, and neurodevelopment, particularly when digestive symptoms are also present.

Which microbiome test is for my child?

INFANT & TODDLER GUT MICROBIOME TEST PERTH

For infants and toddlers from birth to 3 years old. The Baby Biome assesses the infant microbiome at a stage where early-life microbial colonisation is actively shaping immune development, metabolic programming, and gut barrier formation.

Did You Know?
Your child's gut microbiome starts developing from the moment they are born. It is shaped by factors such as the type of birth (vaginal or caesarean), whether they are breastfed or formula-fed, antibiotic exposure, and the foods introduced during infancy. These early influences help lay the foundation for lifelong gut health, immune function, and overall wellbeing.

KID'S & TEENS GUT MICROBIOME TEST PERTH

The Paediatric Biome is designed to assess the gut microbiome, digestive function, and gastrointestinal health of children and adolescents aged 3 to 17 years, using reference ranges calibrated for the maturing paediatric microbiome. Unlike adult gut tests, findings are benchmarked against what is appropriate for children at this life stage.

Gianna's story: eczema, diarrhoea, and food reactions from infancy

This case study shows what becomes possible when a child's chronic gut and skin symptoms are investigated through targeted microbiome testing
rather than managed through trial and error.

Gianna was two years old when she presented with daily eczema flares covering her arms, legs, and torso, diarrhoea occurring up to four times daily, severe itching that disrupted her sleep, multiple confirmed food allergies, and growth that had fallen below the expected percentile for her age. Standard investigations through her GP and paediatrician had not identified an underlying cause, and she had been on topical corticosteroids since infancy with temporary relief only.

Rather than continuing with food elimination and trial and error, gut microbiome testing was used to understand what was actually happening inside her gut; because with symptoms affecting both her gut and her skin simultaneously, the gut was the most clinically logical place to investigate.

What the testing revealed:

Active intestinal inflammation (high calprotectin) indicating gut wall damage
Impaired gut barrier integrity and intestinal permeability (elevated zonulin), explaining food sensitisation
Immune system overactivation (high secretory IgA)
Immune reactions to gluten (positive antigliadin IgA)
Significant dysbiosis affecting both beneficial and opportunistic bacteria
Blood detected in stool indicating active intestinal damage

These findings explained her eczema, diarrhoea, food reactions, and poor immunity through the gut-skin axis; a pathway that is well established in the clinical research but invisible to standard investigations.

Treatment approach:

Treatment was built entirely around the specific microbiome findings and carefully adapted for Gianna's age, growth requirements, and what was practically achievable for a two-year-old and her mum.

Inflammatory and reactive foods were identified via DNA testing and removed alongside confirmed allergens.
Anti-inflammatory support was introduced through omega-3-rich foods, specific nutrients, vitamin D, and specific probiotic strains chosen to match her microbiome results rather than a generic product.

Support was directed toward strengthening the gut barrier and rebuilding the beneficial bacteria essential for nutrient absorption and long-term gut repair, all while maintaining the nutritional adequacy her growth required.
