Thallium, Urine

This test measures the amount of thallium, a toxic heavy metal, in your urine. It helps show whether you have been recently exposed to this substance, which is often associated with industrial work or accidental ingestion. Doctors use these results to see if thallium toxicity might be the cause of symptoms like hair loss, nerve pain, or digestive problems. However, this test cannot identify the specific source of the exposure or determine the extent of permanent organ damage on its own.
