Chromium toxicity occurs when the body is exposed to excessive amounts of chromium, particularly hexavalent chromium, which is a known carcinogen. While chromium toxicity is primarily diagnosed based on exposure history and clinical symptoms, specialized lab testing is essential for confirming exposure levels and assessing the body's chromium burden.
This specialized test measures chromium levels in urine collected over a 24-hour period, providing an accurate assessment of recent chromium exposure and the body's chromium burden. Elevated urine chromium levels can indicate exposure to toxic amounts of chromium and help healthcare providers evaluate the risk for developing serious complications such as lung cancer, skin irritation, or kidney and liver damage.
Chromium exposure can occur through occupational settings, contaminated water, or certain industrial processes. Because symptoms of chromium toxicity can be subtle initially and may mimic other conditions, laboratory testing is fundamental for objectively measuring chromium levels in the body and determining if exposure has reached potentially harmful levels.
Excessive chromium exposure can lead to serious health complications including lung cancer, severe skin irritation and ulceration, kidney damage, and liver dysfunction. Early detection through appropriate testing allows for timely intervention and removal from the source of exposure.
Elevated chromium levels in urine may indicate recent or ongoing exposure to chromium compounds. Your healthcare provider will interpret results in the context of your exposure history, symptoms, and overall health status to determine appropriate next steps, which may include removing exposure sources and monitoring for potential health effects.
