Tellurium dioxide (TeO 2) is a solid oxide of tellurium. It is encountered in two different forms, the yellow orthorhombic mineral tellurite, β-TeO 2, and the synthetic, colourless tetragonal (paratellurite), α-TeO 2. [2] Most of the information regarding reaction chemistry has been obtained in studies involving paratellurite, α-TeO 2. [3]
Tellurite is a oxyanion of tellurium with the formula TeO 2− 3. It is the ion of tellurous acid, and is chemically related to tellurium dioxide (TeO 2), whose mineral appearance also bears the name tellurite. Tellurites are typically colorless or white salts, which in some ways are comparable to sulfite. [3]
3 in vacuum, disproportionating into tellurium dioxide, TeO 2 and elemental tellurium upon heating. [7] [8] Since then, however, existence in the solid phase is doubted and in dispute, although it is known as a vapor fragment; the black solid may be merely an equimolar mixture of elemental tellurium and tellurium dioxide.

A blood test is a laboratory analysis performed on a blood sample that is usually extracted from a vein in the arm using a hypodermic needle, or via fingerprick. Multiple tests for specific blood components, such as a glucose test or a cholesterol test , are often grouped together into one test panel called a blood panel or blood work .
The telluride oxides or oxytellurides are double salts that contain both telluride and oxide anions (Te 2− and O 2−).They are in the class of mixed anion compounds.. Compounds that can be mistakenly called "telluride oxides" are tellurium dioxide and tellurite.
3 in vacuum, disproportionating into tellurium dioxide, TeO 2 and elemental tellurium upon heating.

Whole blood TEM is sensitive to haemostasis affecting agents such as plasma expanders or acidosis while the effects of these agents are hardly identified by plasma based laboratory tests. TEM-guided transfusion of blood products or factor concentrates in cardiac , hepatic and major orthopedic surgery is the main application of the method.
