An arsenic level blood test measures how much arsenic is in your bloodstream at the time of the draw. It is usually ordered when someone has known or suspected exposure to arsenic, such as from contaminated water, certain foods, or workplace dust and fumes.
What it measures
- Total arsenic — The overall amount of arsenic detected in your blood.
- Inorganic arsenic — The more toxic form, often linked to water or industrial exposure.
- Organic arsenic — A less harmful form commonly found in some seafood.
- Arsenic species — Separate forms measured to help tell recent exposure from food-related arsenic.
Who it is for
A doctor or other licensed clinician typically orders this test after a known exposure, or when symptoms and history suggest arsenic may be involved. It is not a routine screening test for most people.
Preparation
No fasting is usually required. Tell your clinician about any seafood eaten in the past few days, because it can raise arsenic levels briefly without meaning harm.
Results and what they mean
Results are reported as a number, often in micrograms per liter, with a reference range from the lab. A clinician interprets the result alongside your history, symptoms, and other tests; a single number alone does not confirm a diagnosis. This is general information, not medical advice.

Frequently asked questions
Does a high result mean I have arsenic poisoning?
Not necessarily. Recent seafood can raise levels temporarily. Your clinician will consider timing, symptoms, and other tests before drawing conclusions.
How long does arsenic stay in blood?
Arsenic leaves blood fairly quickly, often within a few days. A blood test is best for recent or ongoing exposure.
Can I get this test without a doctor?
Some labs offer it directly, but the result still needs a clinician to interpret it in context. Ask your doctor first.
Is the test painful?
It uses a standard blood draw from a vein, which feels like a brief pinch. Serious problems are uncommon.
