Organic Acid Test (OATS)

Organic Acid Testing (OATS)

An Organic Acid Test (OAT) is a valuable tool used in functional medicine to assess various metabolic functions and identify potential imbalances in the body. Let's break down what an Organic Acid Test is and the markers it can detect in a way that is easy for you to understand.

Organic Acid Test (OAT): Unveiling Metabolic Insights

What is an Organic Acid Test (OAT)? An Organic Acid Test is a non-invasive diagnostic tool that analyses urine samples to provide insights into the body's metabolic processes. Metabolism involves the breakdown of nutrients to produce energy, and any imbalances in this process can contribute to various health issues.

 

What does it detect?

Nutrient Deficiencies:

OAT can identify deficiencies in essential vitamins and minerals crucial for overall health.  Specific markers on the test reveal if the body is not effectively absorbing or utilizing these nutrients, which could lead to various health issues.  Let's explore some key markers in this section:

Vitamin B12 Markers:

Methylmalonic Acid (MMA): Elevated levels of MMA indicate a potential deficiency in vitamin B12. Vitamin B12 is crucial for nerve function, red blood cell production, and overall energy metabolism. A high MMA level suggests that B12 is not effectively utilized by the body.

Vitamin C Marker:

Kynurenic Acid: This marker is related to the metabolism of tryptophan and can indirectly reflect vitamin C status. Vitamin C is a powerful antioxidant and plays a vital role in immune function. Low levels of kynurenic acid may suggest insufficient vitamin C.

Magnesium Markers:

3-Methylglutaconic Acid (3-MGA): Elevated levels of 3-MGA may indicate a deficiency in magnesium. Magnesium is involved in numerous physiological processes, including muscle and nerve function, blood glucose control, and energy production.

Zinc Markers:

Pyroglutamic Acid: Increased levels of pyroglutamic acid may suggest a deficiency in zinc. Zinc is important for immune function, wound healing, and DNA synthesis.

Other Nutrient Markers:

Ascorbic Acid (Vitamin C): While not directly measuring vitamin C levels, the OAT can provide information about the metabolites related to the breakdown of vitamin C, offering insights into its utilization by the body.

Nutrient Deficiencies:

  • Example Condition: Anaemia
  • Markers: Low levels of vitamin B12 and iron markers on the OAT may indicate issues with nutrient absorption or utilization, contributing to anaemia.

 

Mitochondrial Dysfunction:

The test assesses the health of mitochondria, the powerhouses of cells responsible for producing energy.  Markers on the OAT can indicate if there are issues with mitochondrial function, which may contribute to fatigue, muscle weakness, and other symptoms related to energy production.  Let's explore some of these markers in more detail:

Citric Acid Cycle Markers:
