Aluminum

This test measures aluminum accumulation specifically within red blood cells, indicating systemic aluminum burden. Aluminum exposure occurs through contaminated drinking water, certain medications (antacids, vaccines), food additives, and occupational settings. While small amounts are unavoidable, excessive accumulation can interfere with iron metabolism, bone health, and neurological function. High RBC aluminum may suggest either excessive environmental exposure or impaired aluminum elimination. The test is sometimes used to monitor occupational exposure or assess aluminum-related health concerns, particularly in dialysis patients or those with heavy occupational exposure.
