Potentially...
Potentially toxic ranges for blood arsenic:
Greater than or equal to 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. A 24-hour urine arsenic is useful for the detection of chronic exposure

Elevated results may be due to skin- or collection-related contamination, including the use of tubes that are not certified to be trace element free. If an elevated result is suspected to be due to contamination, confirmation with a second specimen collected in a certified trace element-free tube is recommended

Methodology: Inductively Coupled Plasma-Mass
Spectrometry (ICP-MS)
