name
descriptionPeople with genetic variants or acquired deficiencies of plasma cholinesterase that result in lower enzymatic activity can have a very difficult time recovering from surgery. To identify these patients, tests using various inhibitory agents are performed. The most common inhibitors are fluoride and dibucaine. The degree to which the agent inhibits the enzyme (fluoride number or dibucaine number) can be used to predict neuromuscular recovery after surgery. Other inhibitors include chloride, RO 020683, and scoline. This term was created for, but not limited in use to, the Roche cobas Cholinesterase / Dibucaine Gen.2 test kit.

Fully-Specified Name

componentCholinesterase^dibucaine
propertyCCnc  =  Catalytic Concentration
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemSer/Plas
    Ser  =  Serum
    Plas  =  Plasma
scaleQn  =  Quantitative:  The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256
