Toxicology

Heavy Metals Panel (Blood or Urine)

Unit: μg/LID: T001

What This Test Measures

Toxic metals: mercury, lead, arsenic, cadmium, aluminum

Conventional vs. Functional Optimal Range

Conventional "Normal"
Below detection limits μg/L
Your doctor says you're "fine" anywhere in this range
Functional Optimal
Below detection limits μg/L
This is where you actually feel great

The gap between these ranges is why you feel terrible with "normal" labs. Conventional medicine waits for disease. Functional medicine optimizes for health.

Gabriel's Take

Heavy metals come from the environment: fish, water, old paint, air, work and some imported products. Lead harms even at low levels, and CDC says no safe blood lead level in children has been found. Mercury affects nerves and kidneys, arsenic raises cancer risk, and cadmium harms kidneys and bones. Use a validated test: blood lead for lead, blood mercury for mercury from fish, a 24-hour urine for other mercury. Provoked urine tests (collected after taking a chelating drug) are not validated and can look high without a real problem (American College of Medical Toxicology), and commercial hair tests gave conflicting results across labs (JAMA, 2001). The first step is always finding and removing the source. Chelation is a prescription treatment with serious risks, including dangerously low calcium, kidney damage and deaths, and happens only under a licensed clinician.

When This Test Is High

Heavy metal toxicity, environmental/occupational exposure

When This Test Is Low

Low body burden

Related Conditions

Mercury: neurological, kidney damage; Lead: cognitive, cardiovascular; Arsenic: cancer; Cadmium: kidney, bone; Aluminum: neurological

Recommended Follow-Up

If elevated on a validated blood or urine test, find and remove the source first; a licensed clinician (often a medical toxicologist) decides whether chelation is needed
