Part Descriptions

LP15315-2   Acetylcholinesterase
An enzyme that catalyzes the hydrolysis of ACETYLCHOLINE to CHOLINE and acetate. In the CNS, this enzyme plays a role in the function of peripheral neuromuscular junctions. EC 3.1.1.7. Source: National Library of Medicine, MeSH 2006

LP15315-2   Acetylcholinesterase
Acetylcholinesterase, an enyzme (EC 3.1.1.7) (AChE) that controls synaptic and neurohumoral cholinergic activity by hydrolyzing the neurotransmitter acetylcholine, is also known as RBC cholinesterase, erythrocyte cholinesterase, or (most formally) acetylcholine acetylhydrolase. The ACHE gene is mapped to chromosome 7q22. AChE is found primarily in the blood on red blood cell membranes, in neuromuscular junctions, and in neural synapses. Two main clinical diagnostic uses are: 1) a second trimester screening test for fetal neural tube defects using amniotic fluid and, 2) in the general population, to detect past exposure to organophosphate insecticides with resultant inhibition of the enzyme using blood.

Change Reason
The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
