Understanding Lab Tests for Mercury Poisoning (Chronic)
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Chronic mercury poisoning is a serious condition that develops when a person is exposed to lower levels of mercury over an extended period of time. Unlike acute poisoning, chronic mercury exposure can cause gradual onset of symptoms including mood swings, memory loss, and physical tremors. Blood testing is essential for confirming elevated mercury levels and diagnosing this condition.
Recommended Test
Mercury Blood
This test directly measures mercury concentration in the blood and is the primary diagnostic tool for chronic mercury poisoning. High levels of mercury in the blood over a prolonged period serve as a key indicator of this condition. The test helps confirm the diagnosis when symptoms like mood swings, memory loss, and tremors are present, enabling healthcare providers to initiate appropriate treatment and identify the source of exposure.

Diagnosing Chronic Mercury Poisoning
Because symptoms of chronic mercury poisoning can be subtle and overlap with other neurological conditions, laboratory testing is crucial for accurate diagnosis. Blood mercury levels that remain elevated over time provide definitive evidence of chronic exposure and help healthcare providers determine appropriate treatment strategies.
Understanding Mercury Exposure Sources
Common sources of chronic mercury exposure include certain fish consumption, dental amalgam fillings, occupational exposure, and contaminated environments. Identifying and eliminating the source of exposure is crucial for treatment success and preventing further health complications.
