A heavy metal blood test is a group of tests that measure the levels of potentially harmful metals in the blood. The most common metals tested for are lead , mercury , arsenic , and cadmium. Metals that are less commonly tested for include copper, zinc, aluminum, and thallium. Heavy metals are found naturally in the environment, certain foods, medicines, and even in water.
Heavy metals can get in your system in different ways. You might breathe them in, eat them, or absorb them through your skin. If too much metal gets into your body, it can cause heavy metal poisoning. Heavy metal poisoning can lead to serious health problems. These include organ damage, behavioral changes, and difficulties with thinking and memory. The specific symptoms and how it will affect you, depend on the type of metal and how much of it is in your system.
