Intended Use: Arsenic testing is used to screen for or to diagnose arsenic poisoning or toxicity in those who have may have been acutely or chronically exposed to arsenic.

Clinical Significance: The potentially toxic range is ≥600 ug/L. Blood arsenic is for the detection of recent exposure poisoning only. Blood arsenic levels in healthy subjects vary considerably with exposure to arsenic in the diet and the environment. Chronic arsenic exposure may be best measured with 24-hour urine arsenic testing. Elevated results may be due to skin or collection-related contamination, including the use of a non-certified metal-free collection/transport tube. If contamination concerns exist due to elevated levels of blood arsenic, confirmation with a second specimen collected in a certified metal-free tube is recommended.
