Trimercury Test

The Mercury Tri-Test is a comprehensive functional assessment used to evaluate mercury exposure, body burden, and the body's ability to excrete mercury, distinguishing between its two primary forms: methylmercury and inorganic mercury.

Mercury is one of the most neurotoxic elements in the environment. Exposure occurs through multiple routes, most commonly dietary intake of large fish and seafood (methylmercury), and inorganic mercury from amalgam dental fillings, industrial exposure, or contaminated water. The two forms behave differently in the body, accumulate in different tissues, and require different clinical approaches. Standard mercury testing does not separate them, making it difficult to identify where exposure is coming from or how effectively the body is clearing it.

The Mercury Tri-Test is the only clinical test that uses three sample types simultaneously, blood, hair, and urine, to provide a complete picture of both exposure sources and excretion capacity. Testing is carried out in a CLIA-certified laboratory using patented mercury speciation technology.

What The Test Evaluates

The Mercury Tri-Test measures across three specimen types:

Blood (whole blood):

• Total mercury in blood
• Methylmercury in blood (reflecting recent dietary exposure, primarily from seafood)
• Inorganic mercury in blood (reflecting amalgam or environmental exposure)
• Blood mercury speciation ratio (proportion of methyl to inorganic mercury)

Hair:

• Total mercury in hair
• Methylmercury in hair (a longer-term marker of dietary methylmercury intake, reflecting months of cumulative exposure)
• Hair-to-blood methylmercury ratio (used to assess methylmercury excretion efficiency through the hair pathway)

Urine:

• Total mercury in urine
• Inorganic mercury in urine (the primary excretion route for inorganic mercury)
• Urine-to-blood inorganic mercury ratio (used to assess the body's capacity to excrete inorganic mercury through the kidneys)

Taken together, these three specimen types allow clinicians to identify not just whether mercury is present, but which form is dominant, where it is likely coming from, and whether the body is excreting it effectively or retaining it in tissues.

How The Test Works

The Mercury Tri-Test uses three sample collection methods, all conducted at home or with minimal clinical support:

• A blood draw (venous or finger-prick), arranged with a phlebotomy provider
• A hair sample, collected using scissors from the nape of the neck
• A urine sample, collected in the vessel provided in the kit

All samples are returned to the CLIA-certified laboratory for analysis using patented mercury speciation technology. Results are delivered to Dr. Menka Gupta for clinical interpretation.

Who This Test Is For

This test is used for individuals presenting with or concerned about:

• Regular consumption of large, high-mercury fish including tuna, swordfish, king mackerel, or shark
• Presence of amalgam (silver) dental fillings, past or current
• Occupational or environmental mercury exposure
• Neurological symptoms including brain fog, memory impairment, tremors, or poor coordination
• Fatigue, weakness, or unexplained muscle aches
• Mood disturbances, anxiety, or irritability with no clear cause
• Sensory changes including tingling, numbness, or visual disturbances
• Cardiovascular symptoms with suspected toxic metal involvement
• Children or individuals with developmental concerns where heavy metal exposure is a differential
• Proactive assessment as part of a broader detoxification or functional medicine evaluation

Mercury toxicity is frequently under-investigated in conventional medicine. Symptoms are often attributed to other causes, and standard blood tests do not differentiate between mercury forms or assess excretion capacity. This test provides the clinical specificity needed to build a targeted detoxification protocol.

What The Service Includes

• Mercury Tri-Test measuring methylmercury and inorganic mercury across blood, hair, and urine specimens
• At-home and clinic-supported sample collection with full instructions provided in the kit
• Laboratory analysis using patented mercury speciation technology in a CLIA-certified facility
• Comprehensive results report detailing mercury levels, speciation ratios, and excretion capacity across all three specimen types
• Results reviewed and interpreted by Dr. Menka Gupta within the context of your clinical presentation, symptom history, and exposure history
• Personalised functional medicine protocol addressing mercury burden and supporting appropriate detoxification pathways

Preparation Guidelines

Follow the collection instructions provided with your kit. To ensure accurate results, avoid consuming seafood for at least 48–72 hours before blood and urine collection, as recent dietary intake can temporarily elevate methylmercury readings. The hair sample should not be dyed or chemically treated in the weeks prior to collection where possible. All three samples should be collected and returned within the timeframe specified in the kit instructions.
