δ-ALA levels in serum and urine—A diagnostic tool for possible lead poisoning

摘要

We present 2 cases of lead poisoning, the first of a child playing with painted toys and the second of an adult on local medicine. The former presented with acute abdomen and the latter with peripheral muscle weakness. We propose that raised serum δ-amino leavulinic acid (δ-ALA) levels strongly point towards the possibility of lead poisoning.
