Reference Interval

0.0-15.0 µg/L

Interpretive Data

Serum aluminum greater than 50.0 µg/L is consistent with overload and may correlate with toxicity.

Elevated results may be due to skin or collection-related contamination, including the use of a noncertified metal-free collection/transport tube. If contamination concerns exist due to elevated levels of serum aluminum, confirmation with a second specimen collected in a certified metal-free tube is recommended.
