Aluminum testing measures exposure to this non-essential metal, found in processed foods, antacids, certain vaccines, antiperspirants, cookware, and municipal water supplies. The body has limited mechanisms to excrete aluminum, so chronic exposure can accumulate, particularly in people with impaired kidney function.
Aluminum accumulation is most concerning when kidney function is reduced, since excretion falls behind intake. Elevated levels are associated with neurological effects in susceptible populations, though the relationship to cognitive decline in healthy adults remains debated. Common contributors include aluminum-containing antacids, antiperspirants, and acidic foods cooked in aluminum cookware. Testing is most relevant for those with kidney disease or suspected environmental/occupational exposure.
Optimal Aluminum (Whole Blood): 0-7 µg/L.
Typically re-tested every 26 weeks.
