• Suspected heavy metal exposure: environmental or occupational mercury exposure.
• Neurological symptoms: tremor, memory changes or concentration difficulties.
• Fatigue: persistent tiredness without clear explanation.
• Immune symptoms: recurrent infections or altered immune response.
• Gastrointestinal symptoms: digestive discomfort or unexplained changes in bowel habits.
• Cardiovascular concerns: assessment alongside cardiovascular risk factors.
• Renal considerations: monitoring where kidney function may be relevant to metal handling.
• Dietary exposure: high consumption of fish or seafood.

Overview

The Mercury Tri-Test uses mercury speciation analysis to directly measure methyl mercury and inorganic mercury across three sample types: whole blood, urine and hair. This multi-matrix approach allows differentiation between mercury forms that vary in source, distribution and biological behaviour.

Clinically, this test may be useful when exploring mercury exposure patterns from dietary, environmental or occupational sources. Measuring both methyl mercury and inorganic mercury can add context regarding exposure type and how mercury is distributed and eliminated across different tissues.

Practitioners typically interpret results alongside clinical history, dietary intake, environmental exposures and other laboratory findings. When reviewed in context, the test can support informed discussions with clients about mercury exposure patterns and relative distribution across sample types.
