Interpretive Data


Note
Increased ALA concentration is associated with exposure to alcohol, lead, and a variety of other agents. Massive elevation of ALA occurs in the acute porphyrias and hereditary tyrosinemia.

Specimen preservation with acid or base may interfere with results. If collected urine will be used for additional testing, remove the ALA aliquot before adding any acid or base preservatives.
