What This Test Measures

This test screens for five heavy metals: copper, lead, mercury, arsenic, and cadmium. These metals can enter your body through contaminated food, water, or environmental exposure. High levels may cause damage to your kidneys, nerves, or other organs.

Why It’s Done

Your healthcare provider may order this test if you have symptoms like nausea, fatigue, numbness, or organ-related issues. It’s also used in occupational health settings or for individuals with a history of heavy metal exposure.

How the Test Works

A blood sample is taken and analyzed using advanced techniques like mass spectrometry or immunoassays to measure metal levels. Results help determine if exposure is causing health concerns.

What to Expect Before the Test

No special preparation is needed, but you may be asked to fast for 8–12 hours before the draw if instructed. Wear comfortable clothing and plan for a short rest afterward.
