Toxic metals challenge test from Doctors Data

Here are the results of my toxic metals urine test (and hair test here) which involved a challenge agent and six-hour timed urine collection (please excuse the typos introduced by OCR):

heavy-metals-colorBarium High

Barium (Ba) has not been established to be an essential element. Elevated levels of Ba often are observed after exposure to Ba (a contrast agent) during diagnostic medical tests (e,g, “barium swallow”, “upper GI series”, “barium enema”, etc.). Elevated levels of Ba may interfere with calcium metabolism and potassium retention. Acutely high intake of soluble Ba-salts (nitrates, sulfides. chlorides) can be toxic. Chronic exposure to Ba may be manifested by muscular and myocardial stimulation, tingling In the extremities, and loss of tendon reflexes. Due to its high density, Ba is utilized to absorb radiation and is utilized in concrete shields around nuclear reactors and in plaster used to line x-ray rooms. Peanuts/peanut butter are very high in Ba so urine Ba may be elevated shortly after consumption of these foods; toxic effects would not be anticipated under such conditions,

The main use of Sa in medicine is as a contrast medium. Long-term retention of Ba can occur – granuloma of the traverse colon has been reported after diagnostic use of Ba­ sulfate, Crystalline Ba-titanate is a ceramic compound which is used in capacitors and transducers. Ba is also used to produce pigments in paints and decorative glass.  Soluble Ba compounds are highly toxic and may be used as lnsecticides. Ba-aluminates are utilized for water purification, acceleration of concrete solidification, production of synthetic zeolites, and in the paper and enamel industries.

Although Ba is poorly absorbed orally «5%)  it can be very high in peanuts and peanut butter (about 3,000 nanograms/gram), frozen and fast foods such as burgers, fries, and hot dogs (400-500 nanograms/gram). It is noteworthy that Ba intake is much higher in children than adults (Health Canada 2005).

Ba levels (and the levels of 16 other elements) in water can be assessed with water testing as provided by DDI. A possible confirmatory test for excessive Sa retention is measurernent of blood electrolytes as hypokalemia may be associated with excessive Ba in the body.  Hair elements analysis may provide further evidence of exosure to Ba.


This individual’s  urine lead (Pb) is higher than  expected  which  means that Pb exposure is higher than that of the general  popu’atlon, A percentage  of assimilated  Pb is excreted  in urine. Therefore  the urine Pb level reflects  recent or ongoing  exposure  to Pb and the degree of excretion  or endogenous  detoxification   processes.

Sources  of Pb  include:  old lead-based  paints, batteries,  industrial  smelting  and alloying, some types of solders,  Ayurvedic  herbs, some toys  and products  from China  and Mexico, glazes  on(foreign)  ceramics,  leaded  (anti-knock  compound)  fuels,  bullets and fishing  sinkers, artist paints with Pb pigments,  and leaded joints  in municipal  water  systems,  Most Pb contamination   occurs  via oral ingestion  of contaminated   food or water or by children  mouthing  or eating  Pb-containing  substances.  The degree  of absorption  of oral Pb depends  upon stomach contents  (empty stomach  increases  uptake)  and upon the essential  element  intake and Pb status.  Deficiency  of zinc, calcium  or iron increases  Pb uptake.  Transdermal  exposure  is significant for Pb acetate (hair blackening  products).  Inhalation  has decreased  significantly  with almost  universal  use of non-leaded  automobile  fuel.

Lead accumulates  in extensively  in bone and can inhibit formation  of heme and hemoglobin  in erythroid  precursor  cells, Bone Pb is released  to soft tissues  with bone remodeling  that can be accelerated  with growth,  menopausal  hormonal  changes,  osteoporosis,   or skeletal  injury,  Low levels of Pb may cause  impaired  vitamin  D metabolism,  decreased  nerve conduction.and developmental   problems  for children  including:  decreased  IQ, hearing  impairment,  delayed  growth, behavior  disorders,  and decreased  glomerular  function.  Transplacental  transfer  of Pb to the fetus can occur at very low Pb concentrations in the body. At relatively  low levels,  Pb can participate  in synergistic  toxicity  with other toxic elements  (e,g, cadmium,  mercury),

Excessive  Pb exposure  can be assessed  by comparing  urine Pb levels  before  and after provocation   with Ca~EDTA (iv) or oral DMSA.  Urine Pb is higher post-provocation   to some extent  in almost everyone,   Whole  blood analysis  reflects  only recent ongoing  exposure  and does  not correlate well with total body retention  of Pb, However,  elevated  blood Pb is the standard  of care for diagnosis of Pb poisoning  (toxicity).

This individual’s  urine nickel  (Ni) is elevated  which mayor  may not be of significance.  Urinary excretion  of nickel bound to cysteine  or other thiol compounds  (such as glutathione)  or to amino acids (histidine,  aspartic  acid, arginine)  is the predominant  mode of excretion.  With the exception of specific  occupational  exposures,   most absorbed  Ni comes from food or drink, and intakes  can vary by factors  exceeding   100 depending  upon geographical  location,  diet, and water  supply. Depending  upon chemical  form and physiological  factors,  from  1 to 10% of dietary  Ni may be absorbed  from the gastrointestinal  tract.  Urine Ni only reflects  recent exposure  to Ni and May vary widely  from day to day.

Sources  of nickel are numerous  and include the following.

• Cigarettes  (2 to 6 mcg Ni per average  cigarette)
• Diesel  exhaust  (particulates  may contain  up to 10 mg/gram)
• Foods,  especially:  cocoa,  chocolate,  soya products,  nuts, hydrogenated   oils, and coffee
• Nickel-cadmium   batteries  (Ni-Cd)
• Nonprecious,   semiprecious  dental  materials
• Nickel-containing   prostheses
• Electroplating,   metal plated  objects,  costume jewelry
• Pigments  (usually  for ceramics  or glass)
• Catalyst  materials  (for hydrogenation   processes  in the food, petroleum  and petrochemical   industries)
• Arc welding
• Nickel refining  and metallurgical   processes

Most clinically  relevant  Ni exposures  are manifested  as dermatoses –   contact  dermatitis  and atopic dermatitis.  However,  Ni hyper-sensitizes  the immune  system  anti may cause  hyperallergenic responses  to many  different  substances,  because  Ni can displace  zinc from binding  sites on enzymes  it can affect abnormal  enzymatic  activity.  Nickel sensitivity  is observed  to be three to five times  more prevalent in females  than in males.

Other laboratory  tests or possible  clinical findings  that may be associated  with Ni exposure  are; hair elements  analysis,  presentation   of multiple  allergic  sensitivities,  dermatitis, positive  patch test for “Ni allergy”,  proteinuria,  hyperaminoaciduria  (by 24-hour  urine amino acid analysis).  Administration of EDTA or sulfhydryl  agents  (DMPS,  DMSA,  D-penicillamine)   may increase  urine Ni levels; ~I,JCh chelator-induced   elevations  mayor  may not be associated  with adverse  health effects.

This individual’s urine thallium (TI) is higher than expected, but associated symptoms or toxic effects mayor may not be presented. Pl’eSer’1tationof symptoms can depend upon several factors including: chemical form Of the TI mode of assimilation.  severity and duration of exposure. and organ levels of metabolites and nutrients that effect the action of TI in the body.

Thallium can be assimilated transdermally, by inhalation, or by oral ingestion. Both valence states can have harmful effects: TI+1 may displace potassium from binding sites and influences enzyme activities; TI+3 affects RNA and protein synthesis. TI is rapidly cleared from blood and is readily taken up by tissues. It can be depOSited in kidneys, pancreas, spleen, liver, lungs, muscles, neurons and the brain. Blood is not a reliable indicator of TI exposure.

Symptoms that may be associated  with excessive TI exposure are often delayed. Early signs of cnronic, low-level TI exposure and retention may include: mental confusion, fatigue, and peripheral neurological signs: parestnesias. myalgias, tremor and ataxia. After 3 to 4 weeks, diffuse hair loss with sparing of pubic and body hair and a lateral fraction of eye- brows usually occurs. Increased salivation occurs less commonly. Longer term or residual symptoms may include: alopeCia, ataxia, tremor, memory loss. weight loss. proteinuria (albuminuria),  and possibly psychoses. Ophthalmologic neuritis and strabismus may be presented.

Environmental  and occupational sources of TI include: contaminated  drinking water, airborne plumes or waste streams from lead and zinc smelting, photoelectric, electrochemical  and
electronic components (photoelectric cells, semiconductors,  infrared detectors, switches). pigments and paints, colored glass and synthetic gem manufacture,  and industrial catalysts used in some polymer chemistry processes. Thallium Is present in some”weight loss” supplements (e.g. Active 8) at undisclosed levels (“trade secret”).

Hair (pubic or scalp) element analysis may be used to test for suspected TI exposure. Although urine is the primary natural route for excretion of thallium, the biliarylfecal route also contributes. Therefore. fecal metals analysis provides a confirmatory  test for chronic ongoing exposure to TI, Clinical findings that might be associated with excessive TI are: albuminuria.
EEG with diffuse abnormalities. hypertension.  and elevated urine creatinine phosphokinase (CPK). No provocation agents are currently available to estimate TI retention by means of urinalysis.

The level of tungsten (W) in this urine sample is higher than expected. After exposure and absorption via inhalation. ingestion or injection, most W is rapidly eliminated via urine and feces, W has no known biological role. Long-term chronic exposures have been associated  with lung disease (pneumoconiosis  or “hard metal lung disease”) and lung cancer. Skin contact with W may produce contact eczema, pruritis. folliculitis and neurodermatitis. Tungsten has an antagonistic relationship  with molybdenum (Mo) decreasing hepatic Mo concentration and reducing the effectiveness  of sulfite and xanthine oxidases.

Tungsten is a silvery-white lustrous element usually obtained as a grey powder and is mainly utilized as tungsten carbide in metal-working,  mining and petroleum Industries. Calcium and magnesium tungstates are widely used in filaments for electric lamps, electron tubes and television tubes,  Since W has the highest melting point of all metals it is used for high-speed and hot-worked steels, Other sources include catalysts and reagents in biological analysis, fire and waterproofing materials, and industrial lubricants.

For people exposed to hard-metal dust, W levies can reach .014 jJg/g in urine. Intestinal absorption of tungsten is rapid and seemingly  significant. W is rapidly transported to the blood
and then to the kidneys for filtration and eventual excretion from the body,  In a rat study, elimination of W via feces was slower than that of urine but reached 52% after three days.  PUlmonary absorption of W-tungstic oxide has been studied in dogs, 60% of W is rapidly deposited in the respiratory  tract and 33% of that fraction reaches systemic circulation. Tungsten is also easily transferred from mother to fetus usually later in gestation.

Urinary W levels may be elevated after administration  of OMPS or DMSA; comparison of urine W before and after provocation provides and estimate of net retention of W over time.

    Great site. Just wondering how you feel about chelating while metal is still present in the body? I have 5 small inconel metal coils. I had a oligoscan recently that showed high toxic metals my last 4 hair tests showed barely visible toxic metals due to me being a very slow oxidiser hence poor eliminator. Thank you. Ben

      Ben, I’m totally unqualified to answer your question about inconel!! I would try joining the Yahoo frequent dose chelation group and asking there…

    Great insights guys, dmsa has a half-life of 9hrs and is a drug that binds heavy metals along with essential minerals, doctors data is a great lab i also recommend great plains labs, EDTA is oral chelator and has a half life of 1 hr. half life pretty much means how long the drug or botanical agent last in your body before it starts wearing out. It is important to be supervised by a naturopath or functional medicine practioner that can hold your hand during the process, silica is good at binding metals along with zeolite. A good indicator of silica deficiency is wrinkles and limes across the forehead, cell salt deficiency) You should also run a creative clearance test before heavy metals detoxification to make sure kidney function is good. Also supporting the adrenal glands will be a good idea becuase heavy metals and adrenal fatigue are usually tied together I recommend, cortex by thorne research, adrenal support by gaia herbs, zinc, alkalize and detox greens powder, cilantro tincture, multi vitamin by now foods. But most importantly infared sauna to help the detoxification phase. Their is no alternative that works better than an infared sauna. Stay healthy guys 🙂

      thanks Steve! how do you feel about far versus near-infrared? I read some bad things about the far, that it was like microwaving yourself…

      • avatar

        steve July 1, 2015, 5:06 am

        That’s a great question, The infared refers to a broad range of frequencies, beginning at the top end of those frequencies used for communication and extending up the low frequency (red) end of the visible spectrum. The range adjacent to the visible spectrum is called the “near infared” and the longer wavelength part is called “far infared”. I personally own a near infared sauna and I am very pleased with it I am not to too concerned about EMF (electric magnetic frequency) emitted by the far infared saunas, I believe that the far or near would still be a great option. I have seen more positive come from detoxing from sauna therapy. Understand your biological makeup and sensitivity, try both and see how you feel, at the end you know yourself more than any expert. Also be sure to replenish with certain minerals. I cant list them all here because everyone is different but I can say magnesium is very important to replenish.
        _stay healthy 😉

    Hey Eric,

    I have been going through “stuff” physically mentally and emotionally for quite a while now. I have done a bunch of different tests and i have been trying to figure out what could be the cause of all of my symptoms. Its just so hard with all the confusion and not getting results with other things and just not having the energy to do things that will help me although i really want to help me.

    Here are some of the tests i did and i just wanted your opinion on this, if heavy metals could be affecting me severely ( root issue ) or if its just a part of the issue. I know emotional and spiritual causes are def deep root causes, but could the physical issues be also the case for me?

    1) My stools tests showed high levels of microscopic yeast along with a low immunity.

    2) Micro nutrient test showed functional deficiencies in key hormones and minerals such as: D3, Zinc, Glutathione, Vit C. It also showed my body was having trouble with the Gluco-Insulin reaction. My naturopath told me to stay away from grains and gluten.

    3) The Urine toxic metal test (post provocation 6 hr collection) showed high levels of lead 9.8 on a reference level of 2.

    Here is the link to the metals test :

    Currently i am doing MCP, modfied citrus pectin, slow chelation but that is what the doctor has me on. I understand i should be doing my own research and stuff but its so hard for me to think clearly and be patient

      Eric May 5, 2015, 4:34 pm

      Yes absolutely physical causes, especially heavy metals can be at the root of your troubles – lead is very damaging and elevates mercury toxicity by 18 times…. I would look into trying frequent dose chelation with DMSA.

        I appreciate your answer, and i apologize because frankly i did not think you replied to my comment.

        Vrajesh Patel September 3, 2016, 4:07 pm

        I am actually now looking into doing chelation with low doses. Just now. i am just so scared that i might get stuck in this chelation cycle and not know what to do if this doesn’t work :'(

        • avatar

          Eric September 4, 2016, 3:55 pm

          I think it’s very safe especially at low doses and if you follow Dr. Cutler’s protocol. You can be so fearful that you never try anything and you will never solve your health problems which might be just as bad, no?

          • avatar

            Vrajesh Patel September 5, 2016, 4:25 pm

            Yea, you’re right. Have to just listen to my body and see where and how i can begin.

    Have you seen or heard Dr. Shade from Quicksilver Scientific on detoxing mercury and the new info out of Sweden on why chelators don’t work well? He is a biochemist that specializes in Mercury toxicity and has developed a protocol for actually testing for it and getting it out of the body. He has a number of videos out – the one where he addresses the IAOMT?? dental group is good. He talks frequently about why some people have higher reactions than others and the methylation cycle. I have all your symptoms. I actually went specifically to a ND who specialized in MTHFR defect and she wasn’t going to test me because I have “not enough symptoms to warrant it”. She ate crow after it came back with not one but two defects.

      Eric October 6, 2014, 5:59 pm

      hi K, I have seen Dr. Shades video… what are they saying in Sweden? What are you going to do?

    • avatar

      Mary October 14, 2014, 5:27 pm

      I found a few discussion threads online about the Dr. Shade protocol (although I didn’t watch the videos Dr. Shade made). The discussions I saw, which were by laypeople, said that Dr. Shade’s product uses a form of silica as its active ingredient.

      The debate in those discissions was whether the silica can remove mercury from anywhere in the body other than the digestive tract. If one believes that the special silica cannot be absorbed out of the gut, then I think one would also have to believe that the silica can only remove any mercury that is already in the gut, not the rest of the body. At least so some people say.

      Andy Cutler’s book mentions silica products (he thinks they are useless, because, he says, they don’t leave the gut, and he even implies that in the gut the silica can’t bind the mercury tightly enough to remove it).

      Just wanted to post this little summary of the Dr. Shade product to save people time in trying to find out what he is selling. I don’t know if it would work or not.

      Dr. Shade does talk a lot about other support for the body – boosting glutathione, and such things. But the product he is selling seems to be mostly the special silica.

        Eric October 14, 2014, 9:27 pm

        That’s interesting Mary. After taking diatomaceous earth for three weeks, I’d be inclined to say that silica does leave the gut. It felt to me like it was affecting my bladder. It’s possible that this is just related to its water absorption properties but I think it’s more than that. Lots of people get blood in their urine for a while after starting diatomaceous earth, so I have to think it does more than just suck up water.

    are you saying that these test are not accurate?

    • avatar

      Eric April 13, 2014, 3:28 pm

      In some of his interviews Andy Cutler explains why challenge tests have little diagnostic utility.

      1. DMSA and DMPS only chelate from extracellular spaces. A one time challenge will only get a small bit of the metals there – not representative of body burden, and NOTHING from the central nervous system and brain where it makes a lot of people sick.

      2. Some people are more tolerant to heavy metals and some more sensitive. The tolerant ones can have high levels on a challenge test and not be sick. The sensitive ones can have a very small quantity of metals mostly in the brain and be very sick.

      3. Some people are not excreting metals well and will have low numbers on a challenge test but still be very toxic from the metals in their brain and organs.

      The challenge test may also make you sicker because you’ll get a one-time, high challenge dose which redistributes metals in your body. The only foolproof test is to do a chelation round with ALA. If you react to it, you’ve got a heavy metal problem…

But then, 12 years ago I fell into a nosedive after moving to South Florida. Now, I know heavy metal toxicity is a significant source of my troubles along with genetic methylation cycle dysfunction and Lyme disease. I spent 18 months chelating the metals out and starting up methylation but stopped when I felt myself circling the drain. Currently going after Lyme and co-infections. More about me here.
