Pseudocholinesterase (Serum (s))
| Testcode: | E_CHE |
| Specimens: | 1 ml Serum (s) |
| Preanalytics/Notes: | To avoid haemolysis, the serum / plasma should be centrifuged before transport if the transport takes a longer period of time. |
| Method: | Photometric assay |
| Dimension: | kU/l |
| Alternate dimension: | µmol/s/l (Factor: 16.6667) Calculator |
| Set-up: | Mon Tue Wed Thu Fri Sat Sun |
| Duration: | 1 day |
| Indication/Significance: | Diagnosis / course evaluation of hepatic cell function at: severe liver cell damage (cirrhosis) acute / chronic hepatitis before administration of muscle relaxants when suspected of a variant of the cholinesterase prolonged apnea after anesthesia Poisoning with pesticides |
| Interpretation: |
