Heavy Metals Testing
Check for lead, mercury and other toxic metals with a validated test
Your request opens ready in Gabriel. Details are verified and nothing is booked or ordered without your approval. Gabriel Care membership is optional.
Evidence status: mixed evidence. Blood lead and 24-hour urine or blood mercury are validated tests. Provoked (challenge) urine testing is not validated and has no normal ranges. Review results with a licensed clinician.

What this test reports
What this test reports
Heavy metals testing measures toxic metals like mercury, lead, cadmium, arsenic, and aluminum in blood or urine. Some of these metals build up over years and can harm the brain, kidneys and other organs, and CDC says no safe blood lead level in children has been identified.
The right test depends on the metal. A venous blood lead test is the standard test for lead (ATSDR). A 24-hour urine collection fits elemental or inorganic mercury, and whole blood fits mercury from fish. Some integrative practitioners use provoked (challenge) urine testing, where you take a chelating drug such as DMSA or EDTA before collecting urine, to estimate stored metals. It is not a validated gold standard: the American College of Medical Toxicology says it has not been scientifically validated, has no demonstrated benefit and may be harmful, and CDC and ATSDR authors concluded it should not be used to diagnose. The chelator raises metals in urine on its own, and there are no normal reference ranges to compare against.
People usually reach for this kind of diagnostic when they want a clearer read on mercury (dental amalgams, fish consumption), lead (old paint, water pipes, bone stores), cadmium (smoking, industrial exposure), especially when symptoms or prior testing still leave blind spots.
Once results are back, you can upload them into Gabriel to connect the findings to symptoms, protocols, and next-step testing instead of leaving them as a static report.
Commonly relevant for: Brain Health Neurodegeneration, Chronic Fatigue Fibromyalgia, Autoimmune Disorders.
Gabriel difference
Why this becomes more useful inside Gabriel
Lead damages the brain, kidneys and bones, mercury harms the nervous system, and arsenic and cadmium are toxic too, so a real exposure is worth finding. The most useful clue is your history: the age of your home, your water, your job and hobbies, the fish you eat, and any supplements, imported spices or remedies. A validated test then shows whether there is a problem. Removing the source comes first; prescription chelation is for confirmed, significant poisoning and only under a licensed clinician, often a medical toxicologist. Upload your results and Gabriel explains them in plain words.
Gabriel interprets results through a functional, root-cause lens: optimal ranges, pattern recognition across multiple diagnostics, and what the findings actually mean for action rather than just classification.
That means this test can feed directly into protocols, practitioner matching, food strategy, and follow-up testing instead of ending as a one-off PDF or lab portal result.
What to expect
What to expect from ordering to results
01
Order
Order directly through Doctor's Data or ask Gabriel whether there is a better path first.
02
Complete
For lead, a blood draw from a vein. For mercury, a blood draw or a 24-hour urine collection, depending on the type of exposure.
03
Interpret
Upload the results to Gabriel for pattern recognition, protocol suggestions, and next-step guidance.
Frequently asked questions
Questions people usually ask before ordering
Symptoms like fatigue, brain fog, headaches, muscle pain, digestive issues and mood changes have many causes, so your exposure history matters most: homes painted before 1978 (lead paint), old plumbing, high-mercury fish, work exposure, hobbies like soldering or pottery glazing, and some imported spices, cosmetics, remedies or supplements. A validated test, such as a blood lead level, shows whether there is a problem.
Blood tests reflect recent or ongoing exposure, and a venous blood lead test is the standard test for lead. A 24-hour urine collection, without a chelating drug, is the usual test for elemental or inorganic mercury, and whole blood for mercury from fish. Provoked (challenge) urine tests, taken after DMSA or EDTA, are not a validated gold standard: the American College of Medical Toxicology says they have not been scientifically validated, have no demonstrated benefit and may be harmful, and there are no normal ranges to compare them with.
The standard panel covers lead, mercury, arsenic, cadmium, aluminum, and thallium. Expanded panels add barium, cesium, gadolinium, nickel, tin, tungsten, and uranium. The most clinically relevant for most people are mercury (dental fillings, fish), lead (older homes, water), and arsenic (rice, groundwater).
Heavy metal panels typically cost $150-300 depending on the lab and number of metals tested. Provoked urine tests (with chelation challenge) cost more due to the chelating agent. Insurance sometimes covers blood lead and mercury testing with documented exposure risk.
Removing the source of exposure is always step one, with good nutrition (enough calcium, iron and protein). Many integrative practitioners add binders such as chlorella, cilantro or modified citrus pectin, which have weak human evidence and can carry metals themselves. Prescription chelation is for confirmed, significant poisoning, such as a high blood lead level, and only under a licensed clinician with lab monitoring: the FDA has approved no over-the-counter chelation product and warns chelation can cause dehydration, kidney failure and death.
