14116-8
LaboratoryIgG synthesis rate [Mass/time] in Serum and CSF by calculation
Definition
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.
