Identify Exposure to Toxic Heavy Metals

The Toxic Element Clearance Profile (TECP) is a toxic exposure profile that measures urinary excretion of 20 potentially harmful toxic metals. In addition to measuring classic elemental toxins such as mercury and lead, this profile includes elements used in medical, aerospace, nuclear, and high-tech electronic industries. Identifying exposure to these metals, then minimizing continued exposure is crucial for clinical improvement.

When should testing for toxic elements be considered?

Occupational and industrial exposure, or exposure through various hobbies may put patients at higher risk for toxicity. Those most at risk include workers in industries such as metal refining, alloying, parts manufacturing in aerospace and machine tools, electronics and computer manufacturing, welding, plumbing, construction, oil refining, mining, waste disposal, pesticide manufacturing and application, pigment and coating manufacturing, petrochemical production, dentistry, firearms and ammunition, and work with glass, dyes, ceramics, or paints.1-3

In addition to occupational exposures, everyday activities may put patients at risk of increased exposure to toxic metals: proximity to the above-mentioned industries where groundwater and air contamination can distribute metals, smoking, living in homes with older wells, pipes, and building materials, consumption of foods known to be contaminated with metals (seafood, rice), taking supplements from manufacturers lacking good manufacturing practice (GMP), use of personal care products and cosmetics, taking certain medications, exposure to emissions and exhaust fumes, and exposure to paints, dental amalgams, and fireworks.1-3

Symptoms and conditions associated with heavy metal toxicity

A wide range of acute and chronic conditions have been associated with toxic heavy metals including, but not limited to:

The element levels measured on the TECP are ratioed to creatinine. By utilizing creatinine concentration as the given ratio standard, the variations in time frames provide useful comparisons upon subsequent testing. Random samplings and/or timed collections provide useful information to screen for exposures.13 Clinicians often use timed samples as part of provoked chelation protocols. Please note, Genova does not provide chelation or provocation protocols and reference ranges apply to non-provoked/non-chelated conditions.

Genova’s Methodology

Metals are measured using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and creatinine via alkaline picrate. Genova measures total levels and does not speciate individual metals. Reference ranges were developed from a healthy population under non-provoked/non-chelated conditions. Reference ranges do not provide absolute levels at which a related symptom may occur — clinical correlation is recommended. Provocation with challenge substances/chelators may raise the urine level of some elements and is thought to represent “body burden.”14 Reference ranges have not been established for provoked urine samples. All toxic metals are reported as micrograms/g creatinine.

What can clinicians and patients expect from toxic element testing?

The Toxic Element Clearance Profile assesses urinary excretion of toxic elements acquired through either chronic or acute exposure. Minimizing or eliminating continued exposure to the toxic element is crucial. Clinicians may choose to initiate detoxification and/or nutritionally supportive treatments based on results if medically appropriate.
