Specimen Preparation

Separate from cells ASAP or within 2 hours of collection. Transfer 2 mL serum to an ARUP Trace Element-Free Transport Tube (ARUP supply #43116) available online through eSupply using ARUP Connect™ or contact ARUP Client Services at (800) 522-2787. (Min: 0.5 mL)

Remarks
Stability

Ambient: Indefinitely; Refrigerated: Indefinitely; Frozen: Indefinitely (If the specimen is drawn and stored in the appropriate container, the trace element values do not change with time.)

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 levels of aluminum in serum should be confirmed with a second specimen due to a high susceptibility of the specimen to collection-related environmental contamination.

Compliance Category
