This test measures the level of mercury in the blood to diagnose acute poisoning or chronic mercury exposure in the body.
Sources of Mercury Exposure:
Mercury is present in the environment in small amounts and is released through:
- Erosion of rocks and soil minerals
- Burning of fuel and waste
Mercury can enter the body through:
- Inhaled air
- Skin absorption
- Food consumption
Most people encounter mercury at low concentrations in daily life, which generally poses no health risk. However, prolonged exposure to moderate levels, especially in workplaces involving heavy metals, may lead to poisoning.
- Do not eat for 2-3 hours before the test; drinking still water is allowed.
- Refrain from smoking for at least 30 minutes before the test.
- Diagnosis and severity assessment in suspected mercury poisoning.
- Occupational monitoring for workers involved in decontamination, hazardous materials handling, and heavy metal industries (along with lead and other heavy metals testing).
Symptoms of Mercury Poisoning:
Acute Mercury Poisoning:
- Burning sensation in the mouth and lungs
- Cough, shortness of breath, chest tightness
- Reduced urination
- Nausea, vomiting, diarrhea
- Rapid heartbeat (tachycardia)
Chronic Mercury Poisoning:
Non-specific symptoms affecting the lungs, kidneys, and nervous system, including:
- Hearing, taste, and smell disturbances
- Blurred vision or narrowed visual field
- Tingling and tremors in hands and feet
- Difficulty walking
- Irritability
- High mercury levels indicate a high probability of poisoning.
- Normal mercury levels suggest the individual has not been exposed to elevated mercury concentrations before the test was conducted.
