Test Overview
Clinical Utility
Inorganic Arsenic includes inorganic, mono- and di-methylated species, correlating with occupational and environmental exposure. Organic Arsenic, including tri-methylated species such as Arsenobetaine is not measured. When Arsenic is ordered, unless Inorganic is specified, a Total Arsenic will be performed and billed, with Inorganic Arsenic performed and billed in addition when the Total Arsenic is elevated.
