Serum light chain assay
In 2009, the International Myeloma Working Group published guidelines making recommendations of when serum free light-chain analysis should be used in the management of multiple myeloma. The serum free light-chain assay in combination with serum protein electrophoresis and serum immunofixation electrophoresis is sufficient to screen for pathological monoclonal plasmaprolif… WebIn univariate analysis, the LRRK2 Parkinson's disease group with negative α-synuclein SAA had higher serum neurofilament light chain than the SAA positive group (median difference 7·7; 1·3 to 14·1). However, this association was not present after adjustment for age and sex (difference in log serum neurofilament light chain –0·19; –0·40 to 0·01).
