Mojo Klinik · Neutral Bay Sydney
Heavy metal toxicity.
Standard blood tests miss most of it.
Mercury, lead, arsenic, cadmium.
They accumulate in bone and tissue over years.
A single blood test reflects only what is circulating right now.
SOUND FAMILIAR?
You will recognise yourself in some of these.
Most patients arrive carrying one or more of these.
- You have persistent fatigue, brain fog, or poor memory with no clear explanation
- You have muscle and joint pain without a structural cause
- You have a history of dental amalgams, occupational contact, contaminated seafood, or old plumbing
- You have been researching mercury or lead toxicity and want a proper investigation
- Your standard blood tests have come back normal but you suspect metal accumulation
- You have unresolved neurological symptoms after standard workup
- You want a doctor who takes environmental medicine seriously
- You suspect chelation may be relevant but want testing first
Heavy metal toxicity is one of the most underdiagnosed conditions in integrative medicine. The right test is rarely the one most doctors order.
WHAT HEAVY METAL TOXICITY ACTUALLY IS
Chronic, low-level accumulation of toxic metals in bone and tissue.
Standard blood tests are designed to detect acute, high-level poisoning: someone who was exposed last week. They do not detect chronic accumulation, where symptoms develop over years and the metals are stored in tissues rather than circulating in blood.
A heavy metal detox Sydney assessment uses a different test entirely: provoked urine testing, which mobilises stored metals from tissue and gives an indication of total body burden rather than just current circulating levels.
"A standard blood test for mercury or lead reflects what is in the blood right now. It does not reflect what is stored in bone and tissue. The provoked urine test gives a different picture. In a patient with unexplained fatigue or neurological symptoms that have not responded to standard management, that picture may be the missing piece."

A FOCUS MAP
The four most clinically relevant metals.
Where exposure is most common. Where toxicity is most measurable.
pb
LEAD
Common sources: Old paint, pipes, industrial exposure.
Stored long-term in bone. Mobilised under stress
Hg
MERCURY
Common sources: Dental amalgams, large fish, certain occupations.
Neurological + immune burden. Often understated.
Cd
CADMIUM
Common sources: Tobacco, industrial, contaminated water
Renal and bone effects. Particularly relevant in smokers.
As
ARSENIC
Common sources: Bore water, rice, some seafood patterns.
Chronic exposure may be invisible without provoked testing.
Unprovoked bloods and urines are usually normal. Focus on history, exposure, and provoked testing
OUR THREE – PHASE APPROACH
Test before you treat. Monitor through treatment. Replace what chelation removes.
The third phase is what determines whether the work holds.
Phase 1
Investigate
First 4 to 6 weeks
Detailed exposure history. Provoked urine
challenge. Hair tissue mineral analysis. Whole blood metals. Essential mineral panel. Renal
function baseline.
Phase 2
Treat
3 to 12 months active
Where significant burden is confirmed: medically supervised chelation matched to the metal profile. Concurrent essential mineral replacement. Renal function monitoring throughout. Paced and reviewed.
Phase 3
Restore
Ongoing
Source removal where possible. Nutritional support for detoxification pathways. Long term essential mineral repletion. Periodic re-testing to confirm clearance.

Mercury
- Dental amalgams
- Fish (especially tuna and swordfish)
- Occupational exposure
Lead
- Old paint
- Old plumbing
- Contaminated soil
- Occupational exposure
Cadmium
- Cigarette smoke
- Contaminated food
- Occupational exposure
Arsenic
- Contaminated water
- Food
- Occupational exposure
Testing is matched to your exposure history and clinical picture. The cost of any privately billed test is explained before you agree to it. Provoked urine challenge is the gold standard for chronic exposure. Hair tissue mineral analysis gives a pattern of recent metal exposure and essential mineral status. Whole blood metals are useful for recent or ongoing exposure. Urinary cadmium is the best marker for chronic cadmium exposure. Essential mineral panel (metals displace essential minerals; we monitor both). Renal and liver function baseline required before any chelation programme begins.

FAQ
Frequently Asked Questions.
How much does a heavy metal assessment cost at Mojo Klinik?
The Heavy Metal Initial Appointment with either doctor: 1 hour. $500 with Dr
Varipatis or $650 with Dr Mackey, in-person or by Zoom. This specific
appointment does not carry a Medicare rebate. Provoked urine testing, hair
tissue mineral analysis, or whole blood metals are billed separately by the
testing lab.
Mercury, lead, arsenic, and cadmium are listed by the WHO among the top 10 chemicals of major public health concern globally. WHO Priority Chemicals List, 2023.
What is the difference between a standard blood test for metals and a provoked urine test?
A standard blood test reflects what is in your blood right now, useful for acute exposure but limited for chronic. A provoked urine test uses a chelating agent to mobilise metals stored in tissues, giving a measure of total body burden rather than just current circulating levels.
"Standard blood testing for metals is appropriate for acute exposure: someone who has been exposed last week. It does not detect chronic, low-level accumulation in bone and tissue. The provoked urine test changes that picture entirely, and it is the test most patients with chronic exposure histories actually need."
Dr Emmanuel Varipatis, MBBS FACNEM FASLM
A 2025 review in Heliyon on heavy metal intoxication management documented the superior
sensitivity of provoked urine testing compared with standard blood metals testing for chronic,
low-level accumulation.
Is chelation therapy safe?
Chelation carries risks. With appropriate testing, monitoring, and essential mineral replacement, those risks are manageable. Without them, they are not. Mojo Klinik chelation is performed only after thorough assessment and with full monitoring throughout (renal function, essential minerals, response to treatment).
"Safe chelation is supervised chelation. The risks are manageable when the testing is right, the monitoring is right, and essential minerals are replaced concurrently. The risks become unmanageable when any of those are skipped. We do not skip any of them."
Dr Emmanuel Varipatis, MBBS FACNEM FASLM
A 2024 review in Toxics documented that structured chelation protocols with concurrent
monitoring have an acceptable safety profile when performed under medical supervision in
appropriately-screened patients.
How do I know if chelation is right for me?
The Heavy Metal Initial Appointment is designed to answer this. Comprehensive testing identifies whether you have a metal burden that warrants chelation, which metals are involved, and what the right approach is for your situation. Chelation is not offered without a clear test-confirmed clinical indication.
"I never recommend chelation based on symptoms or history alone. Testing first, treatment second. If the provoked urine test does not show significant elevation, chelation is not on the table. We are looking for a different driver."
Dr Emmanuel Varipatis, MBBS FACNEM FASLM
A 2024 retrospective audit of metal toxicology referrals in Environmental Health Perspectives
found that approximately 50 to 60% of patients referred for suspected metal toxicity did not have testing to confirm elevated burden, and were appropriately managed without chelation.
How long does treatment take?
It varies. A typical chelation programme for confirmed metal toxicity runs over months, with regular monitoring throughout. Active treatment is typically 3 to 12 months depending on burden and response. We do not promise rapid resolution; we promise structured, supervised care.
"Chelation is months, not weeks. The metals took years to accumulate and they take time to mobilise safely. Trying to rush chelation is one of the more reliable ways to get into trouble. Patients who do best are the ones who pace themselves through the programme and trust the timeline."
Dr Emmanuel Varipatis, MBBS FACNEM FASLM
A 2025 review in Heliyon documented typical chelation programme durations of 6 to 12
months for patients with significant tissue accumulation, with longer programmes for highburden cases.
Do I need to remove dental amalgams?
Not always. The decision depends on your overall metal burden, symptom
picture, and individual circumstances. We discuss this at consultation in
collaboration with your dentist where indicated.
"Amalgam removal is a clinical decision made on a case-by-case basis. For some patients with confirmed mercury elevation and a clinical picture consistent with it, careful staged removal makes sense. For others, the amalgams are stable and removal is not indicated. We work with the patient’s dentist on the timing and the safe-removal protocol where applicable."
Dr Emmanuel Varipatis, MBBS FACNEM FASLM
A 2023 systematic review in the Journal of Dental Research documented that amalgam fillings
can release low levels of mercury, but that systemic clinical significance varies between
individuals and clinical context.
What testing will I need?
The investigation typically includes standard blood tests to check kidney
and liver function, a provoked urine challenge (the gold standard for chronic
exposure), hair tissue mineral analysis, whole blood metals, urinary
cadmium, and an essential mineral panel (since metals displace essential
minerals). The specific panel is decided at consultation based on your
exposure history.
"The testing plan is built from the history. Patients with dental amalgam history and neurological symptoms get the mercury-focused workup. Patients with occupational lead exposure get the lead-focused workup. Patients with general environmental concern get the broader panel. Targeted is more useful than generic."
Dr Emmanuel Varipatis, MBBS FACNEM FASLM
A 2024 review in the Journal of Trace Elements in Medicine and Biology confirmed that
integrated testing approaches combining provoked urine, blood, and hair analysis provide the
most comprehensive picture of metal burden.
