Toxic Elements Screen (TES) in Urine

Brief Description

This inductively coupled plasma mass spectrometer method uses a multi-internal standard dilution technique to provide rapid and accurate quantification of multiple elements; Arsenic (As), Beryllium (Be), Cadmium (Cd), Barium (Ba), Thallium (Th), Lead (Pb), and Uranium (Ur) in urine. This procedure can be used for all 7 elements or subset of the 7 elements.
