Trends in Blood Lead Levels Quantified by ICP-MS: A Reference Laboratory Retrospective Study.BACKGROUND
 The analysis of blood lead concentration was performed in venous whole blood specimens using inductively coupled plasma mass spectrometry (ICP-MS). 
ICP-MS
The objective of this study was to perform a retrospective analysis of patient blood lead concentrations reported by ARUP Laboratories to evaluate the frequency of blood lead concentrations greater than 3.5 µg/dL.
