Functional Testing

Functional testing refers to tests that help to diagnose difficult to resolve health issues, such as digestive dysfunction, neurological concerns and nutrient deficiencies. These tests can also help to give you a better understanding of the unique way that your body functions, allowing for highly personalised treatment.


What we offer at Barangaroo:



Organic Acid Testing (OAT)


The OAT is a test that provides an assessment of the body’s biochemistry, at the present time, through the analysis of over 70 urinary metabolites.   The organic acid markers (metabolites) provide a snapshot of: Bacterial, yeast or fungal clusters in the gut; what is happening in the detoxification pathways; adrenal function and neurotransmitter abnormalities; mitochondrial function and nutrient deficiencies.


People who may benefit from the OAT include any person who has a chronic health condition where multiple body systems may be affected, such as: Chronic fatigue, Digestive issues, ADHD, Auto-immune diseases.

DNA Testing


DNA testing is done via an oral swab which is analysed for variations in genes known as single nucleotide polymorphisms (SNP’s).  SNP’s may affect enzyme function, nutrient metabolism and protein expression.    If we inherit a SNP from one of our parents (Heterozygous) the impact on a person’s health is less significant than if both parents had the same SNP (Homozygous).    As an example, the MTHFR SNP’s affect methylation required for:  DNA synthesis & repair, cell replication & repair, neurotransmitter synthesis & metabolism, energy production and metabolism, hormone regulation and detoxification.


A MTHFR heterozygous person may have 30-40% loss of function and homozygous up to 70% loss of function.   The impact on health includes elevated homocysteine (higher risk of heart disease) inflammation, birth defects, impaired ability to detoxify.


DNA tests currently available include: Wellness Bundle (methylation, detoxification, nutrient metabolism, neurotransmission and endocrinology) – 60 genetic variants; Methylation profile; Hormone and Fertility profile, Mood and Cognition profile, Detoxification profile and Nutrigenomic profile.
