Description
Why It’s Done:
The mercury blood test is commonly used to:
• Diagnose mercury poisoning or mercury toxicity, especially in individuals who may have been exposed to mercury in their work environment (e.g., mining, manufacturing, or laboratory settings) or through environmental sources (e.g., contaminated fish).
• Monitor mercury levels in individuals undergoing chelation therapy (a treatment used to remove toxic metals from the body).
• Evaluate potential exposure to mercury, especially in individuals exhibiting symptoms of poisoning, which may include:
o Tremors, muscle weakness, or coordination problems
o Numbness or tingling sensations
o Vision or hearing changes
o Difficulty breathing (in extreme cases)
• Assess risk in pregnant women and young children, as mercury exposure can harm fetal development and early childhood health.
Preparation:
• Fasting is typically not required, but it’s important to follow your healthcare provider’s specific instructions.
• Inform your healthcare provider of any recent exposures to mercury (e.g., through contaminated fish, certain occupational settings, or use of mercury-containing products).
• You may be asked to avoid consuming certain foods (especially seafood) before the test, as they can temporarily increase mercury levels.
• Avoid taking medications or supplements that may interfere with the test unless instructed otherwise by your doctor.
