# Arsenic (Blood)

> Arsenic (Blood) is measured with a standard blood draw; no fasting is needed. At TestWell it's $84.99 all-in as Heavy Metals Panel (Basic), results in 5–7 business days, drawn at Quest or Labcorp. An out-of-range result is a prompt to look closer, not a diagnosis.

Also known as: arsenic, arsenic, blood, arsenic (blood), arsenic blood.

## What does Arsenic (Blood) measure?

Blood arsenic reflects exposure over the preceding days — from well water, rice-heavy diets, some seafood or occupational contact. Seafood contains harmless organic arsenic that raises the total.

## What does a high Arsenic (Blood) mean?

Confirm the source: recent seafood (benign organic arsenic) versus well water or occupational exposure. Persistent elevation warrants water testing and a clinician's review.
