MERCURY - (U)
Test Code:
HGU
|

| Clinical Information: |
Avoid seafood consumption for three days prior to collection.
Test Indications: Detecting mercury toxicity, even though the correlation between the levels of mercury excretion in the urine and the clinical symptoms is considered poor. 24-hour urine mercury measurement is the preferred test to assess toxicity in patients who have suspected stable and chronic exposure to elemental mercury. While whole-blood mercury concentrations can reflect very large acute mercury exposure, this test becomes less reliable as redistribution to tissues takes place, making 24-hour urine testing more reliable in stable, chronic, or low-grade mercury exposures. Treatment with a chelating agent is indicated in selected patients. Chelators increase the urinary excretion of mercury.
