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 is discouraged and may cause assay interference. When collecting urine for additional tests that require acid or base preservation, the ALA aliquot should be removed prior to the addition of the acid or base.
