ABSTRACT:
The present invention provides a method of improving the sensitivity and accuracy of a lead assay. The method enhances the recovery of lead during isolation of the lead from interfering compounds by maintaining the lead in a sample solution and making the recovered lead available for detection by the assay. An enhancing reagent complexes with the lead isolated in the sample solution. The enhancer includes a chelator having a lead equilibrium binding constant in the range of about 4 log K to about 13 log K. A kit for performing such a lead assay is also provided.
