Heavy Metals Profile II, Urine
Use
Monitor exposure to arsenic, lead, mercury, and cadmium
Special Instructions
This test requires a 24-hour urine collection, and the request form must state the 24-hour specimen volume, if applicable. Avoid contact with metal during the collection, and securely screw the lid on the container. It is important for patients to avoid seafood and red wine 72 hours prior to collection to prevent interference with test results. See individual tests for specific collection times related to industrial monitoring.
Limitations
The test was developed by Labcorp and has not been cleared or approved by the Food and Drug Administration. Therefore, it is intended for clinical laboratory use as determined appropriate by healthcare providers. Factors such as the diet, particularly seafood consumption, can affect arsenic levels due to the presence of non-toxic organic arsenic compounds, potentially complicating the interpretation of total arsenic measurements.
