Arsenic Blood Test (Heavy Metal Screen)

Arsenic is a naturally occurring element widely distributed in soil, water, and some industrial environments. While trace amounts are present in many foods, chronic or high-level exposure can lead to significant health problems affecting the skin, nervous system, cardiovascular system, and multiple organ systems. This blood test measures the concentration of arsenic in your bloodstream to assess recent or ongoing exposure.

This test is particularly relevant for individuals who work in industries where arsenic exposure is possible, such as metal smelting, mining, glass manufacturing, wood preservation, or semiconductor production. It is also useful for those who live in areas with known arsenic contamination in drinking water, or who have unexplained symptoms consistent with arsenic toxicity, including peripheral neuropathy, skin changes, gastrointestinal disturbances, or unexplained anaemia.

The test is performed using a blood sample collected by a trained phlebotomist. The analytical method employed is typically inductively coupled plasma mass spectrometry (ICP-MS), a highly sensitive technique capable of detecting trace levels of arsenic and other heavy metals in biological samples.

Why it matters
Arsenic exposure is often insidious, with symptoms that can be vague and easily attributed to other conditions. Early detection through blood testing allows for timely intervention, removal from the source of exposure, and appropriate clinical management. For occupational health purposes, this test helps ensure workplace safety and regulatory compliance. For individuals with unexplained symptoms or known environmental exposure, measuring blood arsenic provides objective evidence to guide further investigation and treatment. Understanding your arsenic level is a critical step in protecting your long-term health and preventing the progression of toxicity-related complications.
