What this test measures
A heavy metal blood test is a group of tests that measures the levels of possibly harmful metals (like lead or mercury) in your blood.
What your results mean
Reference ranges vary by laboratory and by your age and sex. MedlinePlus does not publish a single normal range for this test — always read your result against the range printed on your own lab report and discuss it with your provider.
Higher-than-normal results
Higher than normal levels of a heavy metal in your blood may mean that you have heavy metal poisoning, but not always. Even if you don't have symptoms, you may still need to avoid all exposure to that metal.
Lower-than-normal results
Normal or low levels of heavy metal in your blood usually mean that you don't have heavy metal poisoning. However, some heavy metals leave your bloodstream quickly and are stored in your tissues, so more tests may be needed if you have symptoms.
