Cholinesterase FS

Product Number : 1 1401


Cholinesterase (ChE) is a group of enzymes that are broken down into choline and thiocholine esters. The names Serum Cholinesterase and Pseucholinesterase are also commonly used. ChE measurements in serum and plasma are synthesized in the liver and are prescribed in the diagnosis of liver disease, nephrotic syndrome and intestinal diseases with protein loss (exudative enterudate).

Very low values ​​may indicate pesticide poisoning. ChE measurement is also part of preoperative diagnostics because ChE is required for the inactivation of muscle relaxants that are often used during surgery.
