# Barium, Whole Blood

> This test measures the amount of barium, a heavy metal, circulating in your blood. It helps determine if you have been exposed to toxic levels of this metal, which can lead to muscle weakness, heart rhythm irregularities, or breathing difficulties. By detecting elevated levels, the test helps rule out barium poisoning as a cause for these symptoms. However, it cannot identify the specific source of the exposure or determine the extent of organ damage on its own.
