NA = not applicable, ACR = urinary albumin/creatinine ratio cFLC = combined free light chains, eGFR = estimated glomerular filtration rate (calculated using the Modification of Diet in Renal Disease (MDRD) equation), FLC = free light chains, Hb = hemoglobin, κ = kappa, HDL = high density lipoprotein, hsCRP = high sensitivity C-reactive protein, λ = lambda, WBC = white blood cell count.
