P118: Heavy/Light Chain Immunoassays for Monitoring of a Multiple Myeloma Patient.
J. Radek1, P. Birkner1, I. Gruber1, D. Trubert-Exinger1
This study compared the performance of Hevylite with SPE and total immunoglobulin assays in the monitoring of a MM patient with a biclonal gammopathy (IgAk and IgGk).
Progression of the disease was detected by the IgGκ/IgGλ HLC ratio (due to suppression of IgGλ) earlier than by the other two methods.
