What's tested

What are heavy metals?

Heavy metals exist naturally in the environment, but industrialization, pollution, and modern consumer products have dramatically increased human exposure. From contaminated water and air to everyday household items and food sources, these toxins can accumulate in the body over time—often without obvious symptoms. Understanding where exposure occurs is the first step in reducing risk and protecting long-term health.

Lead – Found in contaminated drinking water from old lead pipes, deteriorating lead-based paint in homes built before 1978, gasoline, batteries, and industrial materials. Exposure often occurs through tap water, household dust, or soil in urban and older residential areas.

Mercury – Present in seafood like tuna and swordfish, dental fillings, thermometers, fluorescent lightbulbs, and some cosmetics and antiseptics. Industrial pollution can also release mercury into the air, contaminating water and food sources.

Arsenic – Common in pesticides, herbicides, contaminated groundwater, rice, non-organic produce, and certain paints and industrial materials. Long-term exposure is often linked to well water, agricultural products, and processed foods.

Cadmium – Found in cigarette smoke, industrial metal plating, rechargeable batteries, and contaminated soil or crops. Smokers and those exposed to airborne pollution or certain foods like shellfish and leafy greens may be at higher risk.

What are the risks of exposure?

Chronic exposure has been linked to neurotoxicity, cardiovascular disease, kidney damage, and immune dysfunction. Even at low levels, heavy metals can disrupt metabolism, hormone balance, and cognitive function. Because symptoms like fatigue, brain fog, or inflammation often develop gradually, exposure can go unnoticed for years.

Who should consider heavy metal testing?

Heavy metal exposure can go unnoticed for years, often presenting as fatigue, brain fog, mood changes, digestive issues, or unexplained neurological symptoms. Those in high-risk occupations—including construction workers, welders, miners, firefighters, and industrial workers—are frequently exposed to metals like lead, mercury, arsenic, and cadmium through air, dust, or direct contact. People living in older homes may also face increased exposure to lead from aging pipes, paint, and contaminated soil. Additionally, regular seafood consumers, individuals using herbal or imported remedies, and those in areas with known environmental contamination may be at higher risk. Testing provides an opportunity to detect hidden exposure early and take steps to reduce long-term health risks.

What are the benefits of proactive testing?

Heavy metal exposure often goes unnoticed, building up in the body over time while subtly interfering with brain function, metabolism, and organ health. By the time symptoms appear, damage may already be underway. Testing helps detect hidden toxicity early, allowing you to take action before long-term effects take hold while providing critical insight for targeted detoxification strategies.

More about this lab panel

Why consider this panel?

Heavy metals can accumulate in the body over time, interfering with neurological function, cardiovascular health, metabolism, and immune regulation. Chronic exposure is often asymptomatic until toxicity reaches a critical level, contributing to fatigue, cognitive impairment, mood disturbances, and organ dysfunction. This test helps identify hidden heavy metal burden, providing valuable insight for risk assessment, early intervention, and targeted detoxification strategies. It is particularly useful for individuals with unexplained symptoms, occupational exposures, or environmental risk factors.

Does Marek Diagnostics accept insurance?

Marek Diagnostics is a cash-pay service. Our platform offers direct access to comprehensive testing without the limitations, denials, or delays imposed by insurance companies. If traditional insurance covered the kind of proactive, high-quality lab work we offer, Marek Diagnostics wouldn’t need to exist. 

However, many clients successfully use their HSA/FSA to cover their testing costs. Marek Diagnostics is partnered with TrueMed for convenient deployment of HSA/FSA funds at checkout.

My panel Meets Treatment Requirements — what does that mean?

Marek Diagnostics is an extension of Marek Health, the leading health optimization platform designed to turn your results into informed action. 

If your panel Meets Treatment Requirements, you’re eligible to enroll into Guided Optimization, an exclusive program that connects you with:

  • Detailed, expert led lab analysis
  • A consultation with a Marek Health coach and board-certified medical provider
  • A precision health optimization plan
  • Access to high-quality treatment options

If you’re unsure what to do with your results, Marek Health is the bridge between lab results and achieving your goals.

Do I need to pay a separate fee at the lab to get my blood drawn? 

No additional payment is required at the lab. Our expert-built panels include the venipuncture and if you’re building a custom panel or testing biomarkers individually, a $5 venipuncture fee will be automatically added at checkout.
