Thallium (Random or 24 hour) Urine Test
Thallium (Random or 24 hour) Urine Test (Labcorp)
This test measures thallium levels in a random or 24-hour urine sample. Thallium is a metallic element found naturally in the earth's crust. It is used in the production of electronics, optical lenses, pesticides, rodenticides, dyes, and some metal components. Thallium exposure can occur when someone works in an industrial setting where thallium is present. Environmental exposure is also possible from air, water, or soil which is contaminated by emissions from factories. Symptoms of thallium toxicity can include nausea, vomiting, increased blood pressure, rapid heartbeat, muscle weakness, headache, loss of appetite, and seizures. Prolonged exposure which is not treated may result in serious health issues including kidney damage, coma, nerve damage, and heart damage.
Urine thallium testing is typically ordered when someone had symptoms that are associated with thallium poisoning, especially if they work in an industrial setting or live in an area where environmental exposure is likely. Urine testing is most effective at detecting chronic exposure. This test can be performed on either a single random sample or a 24-hour collection. 24-hour specimens can be more informative as they look at the level of thallium excreted over the course of a whole day.
Turnaround for this test is typically 4-7 business days.

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.
Please note in your order if you are requesting a 24-hour 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.
