Sent to ARUP Laboratories, Salt Lake City, UT.


Sunday - Saturday.
Results available within 2-6 days.

Reference Range

0.0 - 2.0 mcg/L.

Test Methodology

Quantitative Inductively Coupled Plasma/Mass Spectrometry.


Elevated results from noncertified trace element-free collection tubes may be due to contamination. Elevated concentrations of trace elements in blood should be confirmed with a second specimen collected in a tube designed for trace element determinations, such as a Royal Blue-top EDTA tube.

Clinical Utility

Thallium is similar to lead and mercury in terms of its toxic properties. Chronic thallium exposure results in alopecia, peripheral neuropathy, seizures, and renal failure. Acute thallium poisoning is characterized by nausea, vomiting, hematemesis, abdominal pain, diarrhea, confusion, coma, and rarely death. Thallium is a byproduct of lead and zinc smelting and is also used in the manufacture of thermometers, rat poisons, insecticides, semiconductors, luminescent tubes, and dyes.
