Organic Acids Test (OAT) (Mosaic Diagnostics)

The Organic Acids Test (OAT) is a powerful, non-invasive tool that provides a detailed metabolic snapshot of your overall health. By analysing urine samples for over 70 markers, this test offers valuable insights into crucial bodily functions, highlighting potential nutrient deficiencies, detoxification issues, neurotransmitter imbalances, and digestive health.

One of the standout features of the OAT is its assessment of mitochondrial markers, which are closely linked to the Krebs cycle – the body’s core energy production process. These markers help evaluate how efficiently your body converts proteins, fats, and carbohydrates into usable energy.

If you’re struggling with fatigue, mood imbalances, poor concentration, or unexplained symptoms, the OAT can help uncover metabolic imbalances at the root.

What is the Organic Acids Test?

By examining these organic acids, the OAT test can uncover a range of imbalances and inefficiencies in key bodily systems. The OAT test is useful for identifying functional deficiencies, microbial overgrowths, and mitochondrial stress.

Here’s a closer look at what the OAT measures:

  • Intestinal microbial overgrowth
  • Oxalate metabolites
  • Glycolytic cycle metabolites
  • Mitochondrial makers (Krebs cycle)
  • Neurotransmitter metabolites
  • Folate metabolism
  • Ketone and fatty acid oxidation
  • Nutritional markers
  • Indicators of detoxification
  • Amino acid metabolites

Altogether, the OAT provides a comprehensive metabolic profile, making it a powerful tool for those looking to get to the root of chronic symptoms and optimise health.

Why Take the Organic Acids Test (OAT)?

The OAT can help identify hidden imbalances in your metabolism, often before they appear in standard blood work. It offers early insight into mitochondrial dysfunction, which can be linked to a wide range of health concerns, including fatigue, mood issues, and chronic illness.

This test helps uncover metabolic stress caused by:

  • Toxic exposure
  • Nutrient deficiencies
  • Intestinal dysbiosis
  • Blood sugar imbalances (dysglycemia)
  • Oxidative stress
  • Poor diet or lifestyle choices

By pinpointing the root causes of dysfunction, the OAT supports targeted, personalised health interventions.

Who Should Take the Organic Acids Test (OAT)?

The Organic Acids Test is especially valuable for those facing chronic, unexplained symptoms that conventional tests often fail to clarify.

You may benefit from the OAT if you experience:

  • Chronic fatigue or low energy
  • Fibromyalgia
  • Multiple chemical sensitivities
  • Headaches or migraines
  • Malaise or generalised poor health
  • Low exercise tolerance
  • Muscle weakness or hypotonia (low muscle tone)
  • pH imbalances or issues with acid–alkaline balance

If you’re experiencing complex or long-term health issues, this test can help to uncover hidden biochemical imbalances that may be driving symptoms and guide more effective, personalised treatment plans.

A urine sample is required for the Organic Acids Test.

3 years and above. Children must not be in nappies.

No, the OAT test should not be used to test for SIBO.

Organic acids help the body carry out important tasks like making energy, keeping pH levels balanced, and helping nutrients work properly. They also play a key role in how the body breaks down fats, proteins, and carbohydrates during digestion and metabolism.

Organic acid disorders are rare inherited conditions in which the body cannot properly break down certain amino acids, carbohydrates, or fats. They are usually detected at birth through newborn screening, and if not carefully managed, can lead to a build-up of toxic substances that may cause serious health problems.
