Arginosuccinic Acid

Elevated levels of argininosuccinic acid (ASA) in the OMX Organic Metabolomics test can indicate several metabolic issues, primarily related to the urea cycle. Argininosuccinic acid is an intermediate in the urea cycle, which is crucial for removing ammonia from the body. High levels of ASA may suggest a deficiency in the enzyme argininosuccinate lyase, leading to a condition known as argininosuccinic aciduria. This condition can result in the accumulation of ammonia, potentially causing neurological symptoms and other metabolic disturbances.

In the context of the OMX test, elevated argininosuccinic acid could also reflect broader metabolic dysfunctions, as the test evaluates a wide range of metabolites to provide insights into an individual's metabolic pathways and health status.

Overall, elevated ASA levels warrant further investigation into the patient's metabolic health and may require interventions to address underlying urea cycle disorders or related metabolic issues.

It is not normally detectable in healthy adults. Adult argininosuccinate lyase insufficiencies are typically treated with a lower protein/higher carbohydrate diet, arginine supplementation, and avoidance of fasting.
