title: Simplified determination of urinary delta-aminolevulinic acid in a wide range of concentrations.
abstract: We describe a simple method for measuring delta-aminole-vulinic acid in urine without the need for the seldom-used but time-consuming internal-standard addition step. It combines the analytical procedure described by Tomokuni and Ogata [Clin. Chem. 18, 1534 (1972)] and a correction based on urine density to obtain, more rapidly and less expensively, results as accurate as those given by the Davis and Andelman [Arch. Environ. Health 15, 53 (1967)] chromatographic method.
