Environmental Toxin Testing
Toxic Heavy Metals Test
Also known as: Dried blood spot & urine toxic and essential elements
Toxic metals and the essential minerals they compete with — measured in blood and urine.
Heavy metals compete directly with the minerals you need: cadmium displaces zinc and mercury disrupts selenium. Different metals and minerals show up best in different samples, so this test uses both a finger-prick blood spot and urine to capture short- and longer-term exposure alongside key essential elements.
What it measures
Blood Spot Markers
Essential minerals and recent metal exposure.
- Zinc and CopperNutritional status and excess.
- Zinc/Copper ratioThese two minerals work against each other.
- MagnesiumIntracellular level.
- SeleniumLong-term intake.
- CadmiumRecent exposure — often from cigarette or vape smoke.
- MercuryOrganic mercury, usually from seafood.
Urine Markers
What your body is clearing right now.
- IodineRecent intake; essential for thyroid hormones.
- BromineCompetes with iodine — found in some flame retardants, baked goods, and pool or spa chemicals.
- SeleniumRecent intake.
- ArsenicCleared quickly, so urine is the best measure — sources include rice, well water, and some seafood.
- CadmiumSmoke and contaminated soil; competes with zinc.
- LithiumA trace element that supports a steady nervous system.
- MercuryInorganic/elemental exposure, e.g. amalgam fillings.
- CreatinineAdjusts for urine concentration.
Who this is for
For anyone with a known or suspected metal exposure, or nervous-system symptoms that haven't been explained.
- Brain fog or forgetfulness
- Frequent headaches
- Low mood
- Fatigue
- Tingling or numbness
- Older home, well water, amalgam fillings, high fish intake, or occupational exposure

How we interpret it
We read every panel through a functional lens — optimal reference ranges, ratios, and cross-panel patterns. Results become part of your written Root Cause Report and your personalized 12-week protocol.
Metal detox is never rushed — we build mineral reserves first, then support gentle, gradual elimination and retest to confirm progress.
Often paired with
Minerals & Metals Test
Cellular mineral status and heavy metal burden — the foundation of the Method.
Blood Minerals & Metals Test
Whole-blood levels of essential minerals and toxic metals, for recent or ongoing exposure.
Mold Toxicity Test
Urine testing for the toxins released by indoor molds.
Environmental Toxicity Test
Your "total toxic load" from pesticides, plastics, solvents, and everyday chemicals.
