What gets tested?

Organic acids are byproducts of metabolic processes in the body. When these compounds accumulate in urine, they can indicate disruptions caused by nutrient deficiencies, enzyme issues, toxins, or medications. The Organic Acids Test measures 76 markers across 10 areas, offering insights into gut health, energy production, nutrient balance, and detoxification for a comprehensive view of metabolic function.

Intestinal Microbial Overgrowth Markers

Detects Candida, Clostridia toxins, mould exposure, and gut microflora imbalances.

Oxalate Metabolites

Highlights oxalate levels, which may contribute to chronic health concerns.

Energy Production & Mitochondrial Markers

Evaluates mitochondrial function and energy generation efficiency.

Neurotransmitter Metabolites

Assesses the breakdown and metabolism of neurotransmitter precursors.

Nutritional Markers

Provides a detailed view of essential vitamin, antioxidant, and co-factor sufficiency.

Detoxification Indicators

Examines oxidative stress and the efficiency of key detox pathways like methylation and sulfation.

How do I prepare for the test?

Be aware that:

Supplements containing arabinogalactan, echinacea, reishi mushrooms, and ribose will directly interfere with your results. 

Sample Type

First-morning urine collection.

FAQ's

Turnaround times vary depending on the test. We aim to process and submit your order to our provider within 2 working days. Test kits are promptly dispatched, and most samples can be collected and returned as soon as you're ready. Some tests may have specific requirements, such as timing around menstruation or return days. These details can be found under "How do I prepare for the test?" and in your kit. Estimated turnaround times refer to how long it takes to analyse your sample once it’s received at the laboratory.

All at-home test kits include clear instructions for sample collection and return, along with necessary packaging. Some tests require you to return the sample on specific days or immediately after collection. Most kits include pre-paid return labels, but some may require you to arrange a prepaid courier collection. Review the instructions carefully before collecting your sample and refer to the contact details in your kit for any questions.

Your kit will come with full instructions and some include video guides. We can support with queries and we encourage you to contact us using the link below before collecting your sample to ensure it can be effectively analysed.

We offer functional testing with and without practitioner interpretation. You can filter tests by consultation on the Functional Testing page. Certain tests, especially those involving clinically significant biomarkers, are only available with interpretation, and some require interpretation by an Integrative Medicine Doctor. We’ll ensure you’re seen by the right practitioner when your results are in. You can purchase a consultation later if you choose standalone testing, but we offer preferential rates for booking upfront. 

We provide functional testing to help you make informed health decisions but do not offer medical advice, diagnosis, or treatment. Results are interpreted through a nutritional, lifestyle, and functional medicine perspective, and it is your responsibility to seek further evaluation, diagnosis or treatment from your primary healthcare provider.

Your digital results report will include indicators of how your specific results differ or align with ‘optimal’ ranges in functional medicine. Some reports include an element of written interpretation. If you’ve purchased a consultation we’ll explain your results and interpret them from a nutritional, lifestyle and functional medicine perspective. We may offer suggestions about how Integrative or Functional Medicine can help and can refer you for full consultation or Integrative Health Assessment with a relevant practitioner if desired. If your test includes a clinically significant biomarker and your result is abnormal, we’ll direct you to consult your primary healthcare provider. If you haven’t purchased a consultation and you’re concerned about your results, you’ll be able to opt-in at this stage.
