Description:
This test measures Mercury levels in a 24-hour urine sample. Most people are exposed to small amounts of mercury in the environment which do not cause health problems. However, exposure to large amounts of mercury or chronic exposure over a long period of time can result in health complications. One of the most common sources of mercury exposure is through eating certain types of fish or seafood. Mercury exposure can also happen in industrial settings such as those which produce electrical equipment, pharmaceuticals and some types of chemicals. Symptoms of mercury exposure can include burning in the mouth or lungs, difficulty breathing, difficulty urinating, increased heart rate, fever, chills, headache, nausea, diarrhea, and abdominal cramps. Over time, mercury poisoning can affect the lungs, kidneys and nervous system.
This test is typically ordered when a person is experiencing symptoms of mercury poisoning or believes they may be at risk for exposure. Mercury testing may be ordered along with a Comprehensive Metabolic Panel (CMP) and Complete Blood Count (CBC) for a more thorough analysis.
A urine mercury test is typically used to look for exposure to metallic or inorganic mercury such as that found in dental fillings and industrial products. A Blood Mercury Test is more appropriate for testing exposure to organic mercury such as that found in seafood.
Mercury urine testing is also included in a Heavy Metals Profile I and a Heavy Metals Profile II.
Turnaround time for this test is typically 3-6 business days.
Check our lab finder to locate a collection site in your area.
Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
Requirements:
Avoid seafood consumption for 48 hours prior to collection.
For 24-hour urine specimen: Obtain a specimen container and instructions from the draw site. Void at 8 AM and discard the specimen. Then collect all urine including the final void at the end of the 24-hour collection period (ie, 8 AM the next morning) in the specimen container. Screw the lid on securely and return the container promptly to the draw site.
If this test is being ordered along with any other blood and/or urine medical testing, it is recommended you have the specimen(s) for your other tests collected at the same time you bring the 24-hour urine specimen to the draw site.
