Microbial Organic Acids (MOAT)

Mosaic Diagnostics

Sample type: Urine

Requires fasting: No

At home test


Details

The Microbial Organic Acids Test (MOAT) measures markers for beneficial bacteria, harmful bacteria, Clostridia species, Candida species, yeast and fungal metabolites, and general markers of dysbiosis. A subset of the OAT, the MOAT is ideal as a follow-up to the OAT and may be recommended by practitioners looking for a specific abnormality, to monitor certain microbial balances, or to assess treatment efficacy.

Organic acids are substances that result from the metabolic processes in the body. Analyzing these metabolites from different metabolic pathways can immediately provide insight into important areas related to gut health. The Microbial Organic Acids Test (MOAT), included in the Organic Acids Test (OAT), specifically measures the metabolites produced by yeast and bacteria. Elevated values in the MOAT may indicate yeast or bacterial dysbiosis.The MOAT is particularly useful as a follow-up to the OAT and may be recommended by practitioners looking for a specific abnormality, to monitor certain microbial balances, or to assess treatment efficacy. However, we strongly recommend that the full OAT be performed as the initial screening test.

Why Use the Microbial Organic Acids Test (MOAT)?
The MOAT is a convenient and effective way to evaluate a patient’s gut health by analyzing 21 organic acids present in a single urine sample. These organic acids are metabolic byproducts that can help healthcare providers detect imbalances in gut health, including harmful bacteria, beneficial bacteria, Clostridia species, Candida species, yeast and fungal metabolites, and general markers of dysbiosis that may be impacting the patient’s overall health.

The MOAT is particularly useful for individuals experiencing chronic health issues that may be related to gut imbalances. Healthcare practitioners can use the MOAT to identify specific abnormalities, monitor microbial balances, or assess treatment efficacy. However, the full OAT is recommended as the initial screening test.
