Proposed thresholds for equivalent iFLC/niFLC ratios between different FLC assays.

iFLC/niFLC ratio for	Freelite	N Latex FLC	Sebia FLC
MM requiring therapy	≥100*	≥50	≥20
High-risk SMM	>20*	>8	>8

Shown are iFLC/niFLC ratios of N Latex FLC and Sebia FLC equivalent to Freelite iFLC/niFLC ratio as part of diagnosis of MM requiring therapy and high-risk SMM
