Background: delta-Aminolevulinic acid is an endogenous compound in the porphyrin synthesis pathways of heme and chlorophyll, and in photodynamic therapy, where 5ALA is being studied in different types of cancer ^1-3   It also is a main indicator of altered metabolism and indicator of porphyria disease and dioxin exposure, and found in the urine of experimental animals exposed to 2,​3,​7,​8-​tetrachlorodibenzo-​p-​dioxin (I)  [1746-​01-​6]​, and in the urine of construction workers exposed to lead. ^4-6
