Most thallium is excreted in the urine and can be found within an hour after exposure and be detected as long as two months after exposure. Interpretation. Patients exposed to high doses of thallium (>1 g) present with alopecia, peripheral neuropathy, seizures, and renal failure.
Urinary thallium levels may reflect recent or chronic exposure and the presence of thallium in urine after acute exposure may persist for up to several weeks. Concentrations less than 5 µg/L are unlikely to cause adverse health effects while concentrations greater than 500 µg/L have been associated with clinical poisoning.
A simple and quick method is described to detect thallium (Tl) in the urine. After complexation with cyanide and tartrate Tl is extracted with chloroform, in which a red complex is formed with dithizone. The sensitivity of detection is 100Μg/l urine. Since symptoms appear generally at concentrations ⩾150Μg/l, this is a suitable method to test a possible thallium poisoning.
Patients exposed to high doses of thallium (>1 g) present with alopecia, peripheral neuropathy, and seizures, and renal failure. Normal daily thallium excretion is less than 1 mcg/day. Exposed patients can have urine thallium excretion greater than 10 mcg/day. The long-term consequences of such an exposure are poor.

The thallium urine test is used to detect the traces of thallium present in the urine. This test helps to detect thallium toxicity or thallium poisoning. What is Thallium? Thallium is a bluish-white metal found in the earth's crust in trace amounts. It is also obtained as a by-product from melting some other metals.
Complications from the radioactive material injected into your body are very rare. Rare complications from the test may include: arrhythmia, or irregular heart beat. increased angina, or pain from ...

Elevated thallium levels in the urine or in other biologic materials such as hair confirms the diagnosis of poisoning. Managing neuropathic pain involves the use of a combination of antidepressants, anticonvulsants, and opiates. Prussian blue is a sequestering agent for certain heavy metal ions and a thallium poisoning antidote.
TlBr has a high density of 7.56 g/cm 3 and high atomic numbers (Tl = 81, Br = 35), which offer excellent stopping power to high-energy ionizing radiation. Meanwhile, its high bandgap of 2.68 eV could enable high intrinsic resistivity for reducing dark current and achieving low electronic noise detector operation.
On a side note, thallium accumulates more readily in the nails than the hair. Nails can also be tested for thallium and other metal toxicities. Detecting Thallium with a Urine Toxic and Essential Elements Test. Thallium toxicity can most accurately be detected in urine with a Urine Toxic and Essential Elements Test. Due to the fact that ...

Thallium is tasteless and odorless and has been used by murderers as a difficult to detect poison. It is found in trace amounts in the earth's crust. Thallium has not been produced in the United States since 1984, but is imported for use in the manufacture of electronics, low temperature thermometers, optical lenses, and imitation precious jewels.
References p. 20 VOL. 2 (lQ57) DETECTION OF THALLIUM IN URINE 19 According to PRICK et al.1, approximately 1-2 mg of thallium are excreted in cases of poisoning. The volume of urine used in this test would therefore contain in a case of poisoning at least 100 /^g of thallium. It is clear that sensivity below 3 /^g per 100 ml would be superfluous.
There are medical tests available to measure levels of thallium in urine and hair. In addition, thallium can also be measured in blood; however, this is not a good indicator of exposure since thallium only stays in blood a very short time. These tests require special equipment that is not usually available in most doctor's offices.

In terms of detection, once spotted thallium poisoning can be confirmed via tests on the urine. A rapid test can be carried out on a urine sample using bismuth nitrate, nitric acid and sodium iodide, which gives a red precipitate in solution if thallium is present.

Thallium salts have some of the characteristics of the ideal poison, being tasteless and colourless, but detection of thallium, for example in urine, is straightforward and can occur even two months after a single dose. The metal remains in the body after death and is not destroyed or lost by burial or cremation.
