LOINC Code

|---|---|---|---|
| name | IgG synthesis rate [Mass/time] in Serum and CSF by calculation | ||
| description | IgG synthesis expresses the synthesis of IgG inside the blood brain barrier, in mg/day, calculated with a formula based on theoretical considerations and on results of clearance studies for a small number of patients. IgG syn = {(IgG.CSF - IgG.serum/369) - (Alb.CSF - Alb.serum/230) x (IgG.serum/Alb.serum) x 0.43} x 0.5. | ||

| component | IgG synthesis rate | ||
| property | MRat = Mass Rate | ||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | Ser+CSF Ser = Serum CSF = Cerebral spinal fluid | ||
| scale | Qn = 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 | ||
