Heavy Metals Panel — Basic (Random Urine)
Use
This test helps identify significant heavy metal exposure by measuring levels of arsenic, cadmium, lead, and mercury in urine. It includes creatinine measurement to normalize for hydration status. Detecting elevated levels may indicate environmental or occupational exposure requiring clinical follow‑up.
Special Instructions
Avoid seafood consumption (typically for 48–72 hours) prior to sample collection to minimize interference from organic mercury ([questhealth.com](https://www.questhealth.com/product/heavy-metals-test-panel-basic/14099M.html?utm_source=openai)). No doctor’s visit needed and independent provider oversight is included in consumer‑initiated ordering ([questhealth.com](https://www.questhealth.com/product/heavy-metals-test-panel-basic/14099M.html?utm_source=openai)).
Limitations
Urine testing may not detect organic mercury forms (common in seafood); only elemental and inorganic mercury are measured ([questhealth.com](https://www.questhealth.com/product/heavy-metals-test-panel-basic/14099M.html?utm_source=openai)). Seafood consumption close to collection may falsely elevate arsenic and mercury levels ([jdos.nicholsinstitute.com](https://jdos.nicholsinstitute.com/dos/MercyOneSiouxlandLabTestMenu/test/1098374?utm_source=openai)).
