LECTURE QUIZ

Knowing the free light chain ratio is important since it can help normalize an increase in light chain values due to inflammation or infection.

Plasma cells make antibodies that fight infection and inflammation. Myeloma comes from a normal plasma cell.

The free light chain ratio helps to determine how much difference there is between Kappa and Lambda measures. If Kappa and Lambda increase at the same time it is not an indication of cancer.
