What does the Arsenic test measure?

Q: What is Arsenic?

Arsenic exists as inorganic (toxic) and organic (seafood-derived, largely non-toxic) species. Inorganic arsenic undergoes hepatic methylation to monomethyl- and dimethylarsenic acids, which are renally excreted. Blood arsenic has a short half-life (hours to days) so reflects very recent exposure.

Q: Why is Arsenic measured?

Blood arsenic is useful in acute poisoning but less informative for chronic exposure than urine. Elevated values require speciation to exclude benign seafood arsenic. Chronic inorganic arsenic exposure causes skin lesions, peripheral neuropathy, vascular disease, and cancer.
