# Barium, Serum or Plasma

> This test measures the level of barium in your blood to check for exposure to this metal. It helps determine if you have absorbed toxic amounts of barium, which can cause muscle weakness, tremors, or heart rhythm issues. This information helps doctors rule out barium poisoning as the cause of your symptoms. However, the test cannot identify exactly how you were exposed or diagnose specific damage to your organs.
