# Mercury (Blood)

> Mercury (Blood) is measured with a standard blood draw; no fasting is needed. A typical reference range is 0.000 – 10.0 mcg/L. 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: mercury, mercury, blood, mercury (blood).
