Abstract
Detection of lead present in a sample, comprising the steps of: (a) adding a lead recovery agent to an assay solution containing lead from the sample; (b) adding to the assay solution a disulfide enzyme which is inhibited in the presence of lead; and (c) correlating the activity of the disulfide enzyme to the amount of lead in the sample. The lead recovery agent enhances the sensitivity and accuracy of the assay such that the assay can be readily automated for detection of lead in whole blood using commercially available automation systems.
