Arsenic, Blood

Overview:

Arsenic occurs naturally in rock and soil and reaches people mainly through drinking water from contaminated wells, through certain occupations, and through food, with seafood and rice being the most common dietary sources. Blood arsenic clears quickly, within days, so this test reflects recent exposure rather than a long-term picture; urine testing is often used where a broader window is needed. Interpretation also depends on the form involved, since the organic arsenic found in seafood is largely harmless and can raise a result without indicating a problem. For that reason results are read alongside a person's recent diet and exposure history.
