Laboratory

A) Monitor vital signs.
B) Obtain an ECG and institute continuous cardiac monitoring.
C) Monitor pulse oximetry and/or arterial blood gases in symptomatic patients.
D) Plasma cholinesterase (butyrylcholinesterase) and red blood cell cholinesterase activities may be useful to confirm exposure and monitor response to therapy but are rarely available in a timely fashion. While there may be poor correlation between cholinesterase values and clinical effects, especially in milder poisonings, acute depression in excess of 50% of baseline activity is generally associated with severe symptoms.
E) If an acute nerve agent exposure is suspected, initiation of treatment is not dependent on laboratory confirmation.
