Setup Schedule
Set up: Mon-Sat; Report available: 1-2 days
Limitations
This measure is very sensitive to aluminum containing medications, e.g., aluminum-containing antacids, and may continue to test as elevated for a prolonged period of time after the medication is stopped.
Clinical Significance
Individuals undergoing hemodialysis are at risk for aluminum toxicity. Prolonged accumulation may cause anemia, encephalopathy, and vitamin D-resistant osteomalacia. Also, workers exposed to high levels or to long-term low levels of aluminum dust are at increased risk of toxicity.
