The Hair Toxic Element Exposure Profile is a functional assessment used to evaluate recent and ongoing exposure to a comprehensive range of toxic heavy metals, using hair as the specimen of choice for detecting cumulative environmental and dietary metal burden. Hair is primarily an excretory tissue. As protein is synthesised in the hair follicle, elements are permanently incorporated into the hair shaft, creating a reliable, time-averaged record of metal exposure over months rather than hours. Toxic elements can be 200 to 300 times more concentrated in hair than in blood or urine, making hair the most sensitive specimen for detecting exposure to metals such as arsenic, lead, mercury, cadmium, and aluminium — metals that may not be detectable at significant levels in a standard blood test taken at a single point in time. This profile is validated by a CLIA-licensed laboratory with over five decades of specialisation in elemental testing, and has been recognised by both the US Environmental Protection Agency and the CDC as a reliable method for assessing toxic metal exposure when performed under controlled analytical conditions. What The Test Evaluates The Hair Toxic Element Exposure Profile measures 31 toxic and essential element markers from a single hair sample: Toxic heavy metals: Aluminium, Antimony, Arsenic, Barium, Beryllium, Bismuth, Cadmium, Cesium, Chromium, Cobalt, Gadolinium, Germanium, Gold, Lead, Mercury, Nickel, Palladium, Platinum, Silver, Tellurium, Thallium, Thorium, Tin, Titanium, Tungsten, Uranium, Vanadium Essential elements also assessed: Copper, Manganese, Selenium, Zinc Each element is measured against validated reference ranges, and results are interpreted in the context of the individual's clinical presentation, exposure history, and symptom profile. How The Test Works The test requires a small hair sample — 0.25 grams — collected from the nape of the neck using scissors. The sample is then sent to the certified laboratory for analysis using advanced instrumentation. Results are typically available within 2 to 4 business days of the laboratory receiving the sample. No blood draw or urine collection is required. The test is entirely non-invasive. Who This Test Is For This test is used for individuals presenting with or concerned about: Fatigue or low energy without a clear conventional explanation Brain fog, memory impairment, or poor concentration Depression, mood instability, or anxiety with suspected toxic component Alopecia or unexplained hair loss Hypertension not adequately explained by lifestyle factors Impaired glucose tolerance or blood sugar dysregulation Kidney function concerns Neurological symptoms including tremors, poor coordination, or Parkinson's-like presentation Vision disturbances Sexual impotence or decreased testosterone production High fish and seafood intake over an extended period Occupational or environmental exposure to heavy metals, industrial chemicals, dental amalgam, or contaminated water Children or adults with developmental or behavioural concerns where metal burden is a clinical differential Proactive assessment as part of a broader detoxification or functional medicine evaluation Chronic low-level metal exposure often goes undetected in standard medical investigations. Symptoms are frequently diffuse, attributed to lifestyle or ageing, and do not point clearly to a toxic cause without targeted testing. What The Service Includes Hair Toxic Element Exposure Profile measuring 31 elements from a single non-invasive hair sample At-home sample collection with full instructions provided Laboratory analysis in a CLIA-licensed facility with over 50 years of specialisation in elemental testing Comprehensive results report detailing toxic metal levels with validated reference ranges across all 31 analytes Results reviewed and interpreted by Dr. Menka Gupta within the context of your clinical presentation, exposure history, and health goals Personalised functional medicine protocol addressing identified toxic element burden and supporting appropriate detoxification and nutritional repletion pathways Preparation Guidelines The hair sample should be collected from the nape of the neck, cut as close to the scalp as possible to reflect the most recent period of exposure. Before collection, avoid using shampoos, bleaches, dyes, or chemical treatments where possible, as these can introduce external contamination that may affect accuracy.
