Comprehensive blood test to measure levels of heavy metals (mercury, lead, cadmium, arsenic) in the body.
Heavy metal and toxicology testing measures the levels of potentially harmful metals in your blood or urine. Common metals tested include lead, mercury, arsenic, cadmium, and aluminum. Exposure to these metals can occur through contaminated water, food, workplace environments, dental amalgams, or consumer products. Even low-level chronic exposure can accumulate over years and cause neurological damage, kidney dysfunction, cardiovascular issues, and immune suppression. Testing is particularly important for people with occupational exposure, those living near industrial sites, and anyone experiencing unexplained neurological symptoms. Results help guide detoxification strategies and identify sources of ongoing exposure.
Key Details
Who Is This For?
People with occupational exposure to metals (manufacturing, mining, painting, welding). Anyone with dental amalgam fillings concerned about mercury exposure. Those living near industrial areas or using well water. People experiencing unexplained fatigue, brain fog, numbness, or neurological symptoms. Anyone following a detoxification protocol who wants baseline measurements.
What's Included
Preparation Required
Fasting for 10–12 hours before your appointment is recommended for accurate results (water is fine). Avoid alcohol for 24 hours and intense exercise for 12 hours before the blood draw. Morning appointments are ideal for consistent hormone and glucose readings. The blood draw typically takes 5–10 minutes.
Biomarkers Tested
4A toxic heavy metal with no safe level of exposure. Even low blood lead levels cause cognitive impairment, kidney damage, and cardiovascular effects. Sources include old paint, contaminated water, occupational exposure, and certain imported products.
A toxic heavy metal found in certain fish (methylmercury), dental amalgams, and industrial sources. Mercury targets the nervous system, causing tremors, cognitive changes, and sensory impairment. Fish consumption is the primary source for most people.
A toxic metalloid found in contaminated water, rice, seafood, and industrial settings. Chronic low-level exposure increases cancer risk and damages the cardiovascular, nervous, and endocrine systems. Testing distinguishes organic (dietary) from inorganic (toxic) forms.
A highly toxic heavy metal primarily from cigarette smoke, industrial exposure, and contaminated food. Cadmium accumulates in the kidneys and liver, causing kidney damage, bone loss, and increased cancer risk with chronic exposure.
