Heavy Metal Screening

A blood and urine panel screening for toxic heavy metal accumulation including lead, mercury, arsenic, and cadmium — environmental contaminants that bioaccumulate in tissues over time. Relevant for anyone with occupational exposure (construction, manufacturing, mining), those consuming large amounts of fish (mercury), residents of older homes (lead paint), smokers (cadmium), and individuals pursuing detoxification protocols who want baseline data before and after treatment.

Heavy metals accumulate in tissues over years and decades of low-level exposure — from contaminated water, dental amalgams, certain foods (particularly rice and seafood), occupational exposure, and environmental pollution. Unlike acute poisoning, chronic low-level heavy metal burden produces vague symptoms that overlap with many other conditions: fatigue, cognitive fog, headaches, joint pain, and digestive disturbance. This screening panel measures the heavy metals most commonly elevated in clinical practice: lead, mercury, arsenic, cadmium, and related toxic elements. Even levels below conventional toxicity thresholds can impair enzyme function, disrupt endocrine signalling, and increase oxidative stress. Lead accumulates in bone and interferes with haem synthesis and neurological function. Mercury disrupts selenium-dependent enzymes critical for thyroid function and antioxidant defence. Cadmium concentrates in the kidneys and is associated with accelerated bone loss. The test is particularly relevant for anyone with occupational exposure (mining, manufacturing, construction, dental work), heavy seafood consumption, a history of living in older buildings with lead paint, or unexplained symptoms that have not responded to standard medical investigation. It also serves as a baseline for those considering chelation therapy or targeted detoxification protocols. ClearLabs processes the blood draw at NATA-accredited laboratories, with results delivered within 2-3 business days. The digital dashboard displays each metal against reference ranges, making it straightforward to identify any that warrant further investigation or intervention. Over 2,000 collection centres across Australia mean convenient access without a GP referral.
