Heavy Metal Testing
Blood testing for toxic heavy metal exposure — typically lead, mercury, arsenic and cadmium.
Chronic low-level exposure causes fatigue, cognitive problems, neuropathy and kidney damage — and is easily missed because symptoms are non-specific. Relevant to anyone eating a lot of large predatory fish, using unregulated supplements, or with occupational exposure.
Optimal ranges, root causes, and the complete correction protocol — nutrition, supplements, lifestyle, hormones and peptides — plus 100+ other markers.

Would you feel it? Symptoms Heavy Metal Testing helps explain
People rarely search for a marker — they search for how they feel. These are the complaints where this marker is worth checking, and whether it is a first-line test or a follow-up once the obvious causes are ruled out.
Why your Heavy Metal Testing might be wrong
Most abnormal results are interference, not disease. These are the things that measurably move this specific marker — check them before you change anything. Each one says whether the number is wrong and should be repeated, badly timed and should be redrawn, or real with a cause worth explaining.
Ordinary tubes leach measurable metal. Trace-element testing requires specific royal-blue-top tubes, and using the wrong one produces meaningless high results.
Confirm the correct tube was used before believing a raised result.
Fish and shellfish contain organic arsenic — harmless, and indistinguishable from toxic inorganic arsenic on a total arsenic test. It reliably produces alarming results.
Avoid all seafood for 72 hours before. If arsenic is high, ask for speciated testing.
Chelation-provoked urine testing produces high results in everybody, has no validated reference range, and is not endorsed by any toxicology body.
Unprovoked testing only. A provoked result is not evidence of poisoning.
What Heavy Metal Testing means in combination
A single marker tells you a little. Combinations tell you the story — these are the named patterns this marker takes part in, and what each one points at.
Fish contains organic arsenic, which is harmless and indistinguishable from toxic inorganic arsenic on a total arsenic test. It reliably produces frightening results in people who ate sushi that week.
Avoid all seafood for 72 hours before testing. If arsenic is genuinely high, ask for speciated testing to separate the forms. And note that chelation-provoked testing has no validated reference range and is not endorsed by any toxicology body.
