| GENERAL INFORMATION | |
|---|---|
| Expected TAT | 2 - 4 days |
| Clinical Use | Approximately 1 in every 2500 individuals has inherited defective or deficiency of the enzyme (pseudocholinesterase) that metabolizes succinylcholine (a anesthetic agent). With ''normal'' dosage, these individuals have prolonged apnea. Such individuals are responsive at much smaller concentrations of this anesthetic agent than the general population. Low concentrations of Pseudocholinesterase are observed in individuals exposed to organophosphorous insecticides and patients with hepatic dysfunction. |
