Heavy Metals Test Kit

Test ID: BU-746 | Sample Type: Dried Blood Spot + Dried Urine Strip | Technology: ICP-MS | Results in 3–5 Working Days

Could Heavy Metal Exposure or Mineral Imbalance Be Affecting Your Health?

Heavy metals such as mercury, arsenic, and cadmium accumulate silently in the body — through food, water, dental work, and environmental exposure. Essential minerals like selenium, zinc, magnesium, and iodine are equally critical: too little or too much can disrupt hormones, energy, immunity, and neurological function.

This at-home test screens for 14 toxic and essential elements across both dried blood spot and dried urine samples, using ICP-MS technology — the gold standard for trace element analysis. It gives you a clinically meaningful picture of your toxic burden and nutritional status in a single test.

What This Test Measures

Dried Urine — Toxic & Essential Elements (ICP-MS):

• Iodine (I) — essential for thyroid hormone production; deficiency causes fatigue and metabolic slowdown
• Bromine (Br) — found in flame retardants and some medications; elevated levels may interfere with iodine uptake
• Selenium (Se) — antioxidant mineral critical for thyroid conversion and immune defence
• Lithium (Li) — trace mineral with neurological roles; measured to assess intake and potential excess
• Arsenic (As) — toxic metalloid found in rice, seafood, and contaminated water; linked to cancer and organ damage at high levels
• Cadmium (Cd) — toxic metal from cigarettes, contaminated soil, and food; accumulates in kidneys over time
• Creatinine (Crtn) — used to adjust urine element results for concentration, ensuring accuracy

Dried Blood Spot — Essential & Toxic Elements (ICP-MS):

• Mercury (Hg) — toxic heavy metal from fish, dental amalgam, and industrial exposure; affects the nervous system
• Selenium (Se) — blood-level selenium reflects longer-term status than urine alone
• Cadmium (Cd) — blood measurement reflects recent or ongoing exposure
• Zinc (Zn) — essential for immune function, wound healing, and hormone synthesis
• Magnesium (Mg) — involved in 300+ enzymatic processes; deficiency is common and often missed
• Copper (Cu) — essential for red blood cell formation and connective tissue; imbalance affects energy and immunity

Why Sample Type Matters

Each element behaves differently in the body — how it is stored, excreted, and when it appears in blood versus urine varies significantly. Testing a single sample type can produce misleading results for certain elements. ZRT Laboratory analyses each element in the most clinically relevant sample type, giving you results that are both accurate and actionable — not just a long list of numbers.

Who Is This Test For?

This test is suitable for adults and children who:

• Eat fish or seafood regularly, particularly high-mercury species such as tuna, swordfish, or shark
• Have mercury dental fillings (amalgam)
• Smoke or live with a smoker
• Live near industrial areas, older properties, or areas with known contamination
• Work in mining, construction, manufacturing, agriculture, or other high-exposure industries
• Experience unexplained fatigue, brain fog, digestive issues, or neurological symptoms
• Are pregnant or assessing risk for a young child
• Want to understand their mineral status and nutritional gaps
• Have thyroid-related health concerns

Frequently Asked Questions

What is ICP-MS and why does it matter?
ICP-MS (Inductively Coupled Plasma Mass Spectrometry) is the most sensitive and precise method for measuring trace elements in biological samples. It can detect elements at extremely low concentrations — far below what standard laboratory methods can identify — making it the gold standard for heavy metals and mineral testing.

How do I know if I have heavy metal toxicity?
Symptoms of heavy metal accumulation are often non-specific and overlap with many other conditions — including chronic fatigue, brain fog, memory problems, mood changes, digestive issues, and tingling in the extremities. The only way to confirm exposure and levels is through accurate laboratory testing. This test measures the most clinically relevant toxic metals in the appropriate sample type for each.

Why are both blood and urine tested?
Different elements are excreted and stored differently. Some toxic metals — like mercury and cadmium — are better measured in blood for recent exposure and in urine for longer-term or kidney-related accumulation. Using both sample types ensures each element is measured where it is most clinically meaningful, rather than defaulting to a single sample type that may miss key results.

Is this test suitable for children?
Yes. The test is suitable for adults and children. Sample collection is non-invasive — the dried blood spot requires only a small finger-prick, and the urine collection is straightforward. If testing a child, please follow the collection instructions carefully.

Does the price include the laboratory fee?
Yes. The full laboratory analysis fee is included in the purchase price. There are no additional charges. You are only responsible for posting your samples to the laboratory.

How long is the kit valid for?
The kit must be used within 12 months of the purchase date.

Can I take this test if I eat fish regularly?
Yes, and it is particularly recommended if you eat fish frequently — especially high-mercury species such as tuna, swordfish, or shark. Regular fish consumption is one of the most common sources of mercury exposure, and this test will give you a clear picture of your actual mercury burden alongside other key elements.

What happens if my results show elevated heavy metals?
Your results report will include a written commentary from a Hormone Specialist PhD Doctor explaining what your levels mean and what to do next. If elevated toxic metals are identified, the report will guide you on further steps, which may include dietary changes, targeted supplementation, or referral to a healthcare professional.
