Overview of the Mercury (Blood) Test
The Mercury (Blood) test measures Mercury circulating in the bloodstream, providing information about recent or ongoing systemic exposure.
The test assesses 1 toxicology biomarker: Mercury (Blood).
Mercury exists in elemental, inorganic and organic forms.
Different sources produce different exposure patterns.
Blood Mercury is particularly useful for evaluating recent methylmercury exposure, which most commonly comes from eating fish and seafood containing elevated Mercury concentrations.
It can also detect exposure from other environmental or occupational sources.
Mercury absorbed into the body can affect the nervous system and other organs when exposure is sufficiently high.
However, clinical toxicity cannot be diagnosed from one numerical blood result alone.
Diet is an important part of interpretation.
People who regularly eat certain large predatory fish can have higher Blood Mercury without an obvious industrial exposure.
Urine Mercury provides different information and is generally more useful when the main concern is inorganic or elemental Mercury.
Blood and urine testing can therefore be complementary.
The timing of the sample also matters because blood concentrations reflect relatively recent exposure more strongly than very remote exposure.
A normal result does not necessarily reconstruct historical Mercury exposure from years earlier.
A raised result should lead to assessment of the likely source rather than immediate assumptions about toxicity.
What Does the Mercury (Blood) Test Check?
The test measures Mercury circulating in blood. This test measures 1 biomarker.
Mercury (Blood)
Measures circulating Mercury, supporting assessment of recent dietary, environmental or occupational exposure, particularly methylmercury exposure.
Who May Benefit From the Mercury (Blood) Test?
Blood Mercury testing can be useful when recent systemic exposure is suspected.
People with high intake of selected fish or seafood - Methylmercury exposure can occur through the food chain.
People with occupational Mercury exposure - Blood testing can contribute to toxicology assessment.
People with a known recent Mercury exposure incident - Measurement can quantify systemic exposure.
People with a previous elevated Blood Mercury result - Repeat testing can monitor whether the concentration declines.
Pregnant people with significant Mercury-exposure concerns - Methylmercury is particularly relevant to fetal neurodevelopment.
People undergoing a broader heavy-metal assessment - Mercury can be interpreted alongside Lead, Cadmium and other exposure markers.
How to Prepare
Do not deliberately consume or avoid seafood immediately before testing simply to manipulate the result.
The aim is to assess your genuine recent exposure pattern.
Symptoms and Reasons to Consider the Mercury (Blood) Test
Symptoms of Mercury toxicity vary and are not specific enough to establish exposure without laboratory and clinical context.
Known high Mercury exposure - A documented source provides a clear reason for testing.
Neurological symptoms after a significant exposure event - Specialist assessment may include Mercury measurement.
Very high consumption of high-Mercury fish - Blood testing can assess recent methylmercury exposure.
Occupational exposure in metal, laboratory or industrial work - Biological monitoring can be useful.
A previous elevated Blood Mercury result - Repeat testing can assess response to exposure reduction.
Severe neurological symptoms or suspected acute poisoning require urgent medical assessment.
Blood Mercury is an exposure biomarker and should not be used to diagnose vague symptoms without a plausible source.

When Will I Receive My Results?
The current specialist laboratory turnaround for Mercury (Blood) is approximately 5 days after laboratory receipt.
London Blood Tests currently lists the test at £88.
Specialist trace-metal handling and analysis are required.
Understanding Your Results
A lower result indicates relatively low circulating Mercury at the time of testing.
A raised result indicates increased recent systemic exposure.
The clinical significance depends on the concentration and likely source.
Regular consumption of high-Mercury fish can increase blood concentrations.
Occupational exposure can also contribute.
The result should not be interpreted as a direct measurement of irreversible tissue damage.
Where inorganic exposure is suspected, urine Mercury can provide complementary information.
Reduction or elimination of the relevant exposure source is usually the first step when a genuine elevation is identified.
