Newer biomarkers of kidney damage could also be considered, e.g., Neutrophil Gelatinase-Associated Lipocalin (NGAL), Kidney Injury Molecule-1 (KIM-1), Beta-Trace Protein (BTP), Beta-2 Microglobulin (B2M), Uromodulin, Asymmetric Dimethylarginine (ADMA), Symmetric Dimethylarginine (SDMA), Metabolomic and Proteomic Biomarkers, and MicroRNAs (miRNAs), depending on the capabilities of the center itself. This evidence concerns the gene B2M and Nephropathy.
