name
descriptionMannose-6-phosphate isomerase (MPI) levels are measured in leukocytes for the diagnosis of congenital disorder of glycosylation Ib (phosphomannose isomerase deficiency [CDG-Ib or MPI-CDG]).
statusACTIVE

Fully-Specified Name

componentMannose-6-phosphate isomerase
propertyCCnt  =  Catalytic Content
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.
systemWBC  =  Leukocytes
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
