Diagnosis of arsenic intoxication using 24 hour urine specimens. Total arsenic will be performed first. If the total arsenic concentration is 10 mcg/L or greater, then speciation will be performed and reported. If total arsenic is below 10 mcg/L, total arsenic will be reported as less than 10 mcg/L and speciation will not be performed.
