How is arsenic exposure diagnosed?
There are tests that measure the level of arsenic in your body. Arsenic can be measured in blood, urine, hair and fingernails. Testing urine will tell you if you have been exposed to arsenic in the last few days. Testing hair and fingernails will tell you if you have been exposed to arsenic in the past six to twelve months. These tests will tell you if it was arsenic that made you sick. However, the tests cannot tell if the arsenic will make you sick in the future.
