Provoked urine metals test

What this test is

For this test, you take a medicine first. The medicine pulls metals out of your body. Then you give a urine sample. The idea is to find stored metals a normal test would miss. But the medicine pulls out some metal from almost everyone. This happens even in people with no metal problem. So the result usually looks high no matter what. There is no normal range for a test done this way. There is also no proof that the result matches how much metal you were exposed to. Treating this result as proof of poisoning has caused real harm. This includes loss of minerals your body needs. In rare cases it has caused dangerous drops in blood calcium. If a metal exposure is a real concern, there are safer, proven tests. They do not need this extra medicine step first.
