Arsenic, Urine (random)



Quest Diagnostics Test Code: 270

This test measures levels of Arsenic in the urine. Arsenic is an element which can be toxic to humans. Arsenic is often found in low concentrations in the environment and some types of food. Low levels of Arsenic are not typically harmful. Higher concentrations of Arsenic, such as that found in industrial settings and in products such as pesticide, weed killer and paint, can be far more toxic and dangerous if breathed in or consumed.

A person exposed to high levels of arsenic should seek immediate medical attention as arsenic toxicity can be fatal. Symptoms of acute arsenic exposure can include, abdominal pain, nausea, dehydration, dark colored urine, vertigo, heart problems, and shock. Long-term exposure to lower levels of arsenic can cause red or discolored skin, rash, liver and kidney issues, defects of the nervous system, and the development of certain types of cancer.

Urine is the preferred specimen for detecting chronic arsenic exposure. This test uses a single random urine sample. A 24-Hour Arsenic Urine Test is also available. A Blood Arsenic Test is available for detecting acute arsenic exposure. Please note that arsenic is typically only detectable in the blood for 6 hours to 2 days.

Arsenic testing is also included as part of the Heavy Metals II Profile.

Turnaround for this test is typically 3-4 business days.
