74868-1
LaboratoryIgG.kappa/IgG.lambda [Mass Ratio] in Serum or Plasma
Definition
Measuring both the IgGκ and IgGλ, calculating the IgGκ/IgGλ ratio, and then comparing with normal subjects levels may provide a more sensitive indication of clonality. Usage of the IgGκ/IgGλ ratio may also compensate for any fluctuations in plasma volume and adjust for half-life variations. This term was based on, but not limited in use to, the Hevylite Human IgG Kappa and Lambda assays.
