## Indications for use
The Hevylite IgG Kappa kit is a quantitative in vitro assay intended for the measurement of IgG Kappa (IgG heavy chain and Kappa light chain intact immunoglobulin) in serum using the Binding Site Optilite analyser. Measurement of Hevylite IgG Kappa is used alongside Hevylite IgG Lambda to calculate the IgG Kappa / IgG Lambda ratio. The Hevylite IgG Kappa / IgG Lambda ratio can be used when monitoring previously diagnosed IgG multiple myeloma patients and is used in conjunction with other laboratory tests and clinical evaluations. The assignment of complete response is reliant upon other tests including immunofixation, bone marrow and urine assessments.
