335: Cholinesterase, Plasma Print View
Cholinesterase, Plasma KS  Male: 3334 - 7031
Female: 2504 - 6297 
IU/L 

PRIMARY
1 Plasma EDTA 1 (0.5) mL   Refrigerated - 21 Day(s)/Room Temperature - 21 Day(s)/Frozen - 30 Day(s)  
ALTERNATE

Approximately 1 in every 2500 individuals has inherited defective or deficiency of the enzyme (pseudocholinesterase) that metabolizes succinylcholine (an 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.

Draw a lavender-top (EDTA) tube of whole blood. Spin tube to
separate plasma. Pour plasma into plastic aliqout tube and
refrigerate until shipping. Ship plasma sample refrigerated.
Do not send packed cells. Do not send one tube of whole blood.


Plasma cholinesterase results are not accurate if plasma sample
is not separated from RBC's in a timely manner (within 1 hour).
Hemolyzed plasma samples are not acceptable. Hemolysis can lead
to apparent increases in plasma cholinesterase activity, and
could mask an enzyme deficiency.
