a-Ketophenylacetic Acid (from Styrene)

Optimal result: 0 – 0.46 mmol/mol creatinine

When high levels of a-Ketophenylacetic Acid (from Styrene) and a-Hydroxyisobutyric Acid (from MTBE) are found, the function of support systems such as the liver and kidneys may be impaired by excess toxin exposure.

Possible treatment options:

- Avoidance of styrene

- Hydration

- Antioxidants

- B12 may play a role in processing these compounds, so use low dose of Vitamin B12.

The detoxification markers, like a-Ketophenylacetic Acid, reflect increased exposure to environmental toxins, or up-regulation of detoxification pathways in response to stress. Collectively, when these markers are elevated:

1. Identify the source of toxin exposure.

2. Minimize or reduce exposure.

3. Consider the use of antioxidants, like glutathione, plus other nutrients and botanicals to support detoxification.

"Watching my numbers move over the years — instead of forgetting last time's results — completely changed how I manage my health."

"Living across several countries made keeping my lab results organized a real challenge. Healthmatters brought my results from the USA, Spain, and Germany together — 20 years of history, with long-term trends instead of scattered reports."

"Standard lab ranges are too wide for how I practice — 'normal' isn't optimal. I set my own bands, so a client sees yellow before a marker goes officially out of range. That's the conversation I want to be having."
