To measure cholinesterase in serum, there are two types of measurements, the first one is called colorimetric method, and if the colorimetric method measures high cholinesterase, 14,000 U/L is considered a serious condition. This is because when measured by colorimetric method, the reference value should be within 130-310 U/L for both males, females, children and adults. If measured enzymatically, the normal standard value of cholinesterase is usually 5400-32000 U/L for women and 4300-12500 for men, and if measured by enzyme immunoassay, that is, if it is not possible to measure it, the value of cholinesterase of 14000 U/L is not considered serious, but is considered basically normal, and it is considered completely normal, especially for women.
