Tests for the enzymes acetylcholinesterase (also known as RBC cholinesterase) and pseudocholinesterase (also known as butyrylcholinesterase or plasma cholinesterase) which act to break down acetylcholine. Acetylcholine is a critical chemical in the transmission of nerve impulses. Acetylcholinesterase is found in nerve tissue and red blood cells, and pseudocholinesterase is found primarily in the liver.
