700-1600 mg/dL Children and Juveniles 0-1 year 232-1411 mg/dL 1-3 years 453-916 mg/dL 4-6 years 504-1464 mg/dL 7-9 years 572-1474 mg/dL 10-11 years 698-1560 mg/dL 12-13 years 759-1549 mg/dL 14-15 years 716-1711 mg/dL 16-19 years 549-1584 mg/dL

Criterion: Recovery within plus or minus 10% of initial values. Icterus: No significant interference up to an I index of 60 (approximate conjugated and unconjugated bilirubin concentration: 60 mg/dL). Hemolysis: No significant interference up to an H index of 1000. (approximate hemoglobin concentration: 1000 mg/dL) Lipemia (Intralipid): No significant interference up to an L index of 3000. There is poor correlation between turbidity and triglycerides concentration. There is no cross-reaction between IgG, IgA and IgM under the assay conditions. Sera with ill-defined clinical characteristics should first be subjected to protein electrophoresis so that an antigen excess (e.g. gammopathy), if present, can be identified. IgG concentrations of more than 44,000 mg/dl (440 g/l) can cause a high-dose hook effect.
