• Dietary exposure concerns: suspected intake of metals through food or water.
• Environmental exposure: contact with soil, dust or contaminated surfaces.
• Occupational exposure: professions involving metal processing or industrial materials.
• Biliary elimination assessment: exploring potential routes of metal excretion.
• Mercury exposure: suspected intake from fish, dental materials or other sources.
• Lead exposure: concerns related to ageing buildings, pipes or paint.
• Cadmium exposure: possible intake from smoking, food or industry.
• Uranium or thallium exposure: environmental or geographic considerations.
• Infants or children: situations where urine testing is challenging.
• Adults unable to complete urine sampling: alternative assessment method.

Overview

The Fecal Toxic Metals test measures concentrations of multiple metals in stool, including arsenic, cadmium, mercury, lead, antimony, nickel, thallium, uranium and others. Stool analysis reflects oral exposure and, for several metals, biliary excretion, which is a natural route through which the body eliminates certain elements. This method can be especially useful when urine sampling is difficult, such as for infants, children or adults unable to provide an adequate sample.

This assessment may relate to concerns involving dietary exposure, environmental contact, occupational settings, or situations where metals may be ingested through food, water or surface contamination. It may also support the evaluation of potential metal intake in contexts involving fish consumption, industrial environments or older buildings.

Practitioners typically interpret results from this panel alongside exposure history, dietary patterns, home and work environments, lifestyle factors, travel history and information shared by clients. This helps build a clearer understanding of how stool metal levels may relate to reported symptoms or exposure patterns.
