IgA.kappa/IgA.lambda [Mass Ratio] in Serum or Plasma

IgA kappa/A lambda SerPl

Definition

  • Measuring both the IgAκ and IgAλ, calculating the IgAκ/IgAλ ratio, and then comparing with normal subjects levels may provide a more sensitive indication of clonality. Usage of the IgAκ/IgAλ 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 IgA Kappa and Lambda assays.
