LECTURE QUIZ

The Free Light Chain Assay tests to see if there is an excess of Kappa or Lambda light chains. If the results are above 8 or less than 0.125 it shows a significant abnormality that needs to be investigated.

Patients can have higher levels of light chains during baseline testing when experiencing problems with what organ?

Just like with a healthy cell, a myeloma cell releases a protein into the blood. However, the myeloma cell releases parts of the protein, which is known as free light chains.
