Microbial Organic Acids Test (MOAT) – Assessment of Yeast and Bacterial Imbalance

The Microbial Organic Acids Test (mOAT) from Mosaic Diagnostics Laboratory is a urine-based assessment that focuses on organic acid markers related to yeast (Candida) and bacterial (Clostridia) overgrowth in the digestive system. This test represents the microbial section of the full Organic Acids Test (OAT) and provides targeted insight into gut microbiome balance and the potential effects of microbial toxins on overall health.

By analyzing microbial metabolites excreted in the urine, the mOAT helps clinicians identify patterns of dysbiosis—an imbalance of beneficial and harmful microorganisms that can contribute to chronic inflammation, digestive distress, neurological symptoms, and immune dysregulation.

UNDERSTANDING MICROBIAL ORGANIC ACIDS

Organic acids are metabolic byproducts produced during normal biochemical and microbial processes in the body. When certain yeast or bacteria (such as Candida or Clostridia species) overgrow in the gut, they release excess organic acids that can interfere with neurological and metabolic function.

Elevated microbial organic acids can indicate:

• Yeast overgrowth (Candida or other fungi)

• Clostridia bacterial toxins affecting brain and nervous system signaling

• Gut dysbiosis and poor microbiome diversity

• Compromised detoxification or immune function

Imbalances detected by the mOAT have been linked to a wide range of symptoms, including:

• Digestive issues (gas, bloating, constipation, or loose stools)

• Fatigue or low energy

• Anxiety, mood swings, or irritability

• Brain fog and concentration problems

• Behavioral changes in children

• Sleep disturbances

WHO MAY BENEFIT FROM THE MOAT

Practitioners often use the Microbial Organic Acids Test to evaluate individuals with:

• Autism Spectrum Disorders (ASD)

• ADHD or behavioral changes

• Chronic fatigue or brain fog

• Mood or anxiety disorders

• Autoimmune or inflammatory conditions

• Digestive disturbances or suspected yeast/bacterial imbalance

This test is also valuable for monitoring treatment progress in individuals undergoing antimicrobial, probiotic, or gut-rebalancing therapies.

MOAT VS. FULL ORGANIC ACIDS TEST (OAT)

While the mOAT focuses specifically on yeast and bacterial markers, the full Organic Acids Test (OAT) includes a broader range of metabolic, mitochondrial, nutritional, and detoxification markers.

Practitioners typically recommend performing the complete OAT initially for a comprehensive overview, followed by the mOAT as a targeted follow-up test to monitor microbial balance or treatment effectiveness.
