## Indications for use
Hevylite Human IgG Kappa is a quantitative in vitro assay performed on the SPAPLUS analyser for the measurement of IgG kappa (IgG heavy chain and kappa light chain intact immunoglobulin) in serum. Measurement of Hevylite Human IgG Kappa is used alongside Hevylite Human IgG Lambda to calculate the IgG Kappa / IgG Lambda ratio. The Hevylite Human IgG Kappa / IgG Lambda ratio can be used when monitoring previously diagnosed IgG multiple myeloma 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.
