  • Unless otherwise noted, values are maximum biomarker levels. Biomarker values are expressed as pg/ml. AUC, area under the curve; GA, gestational age; EGF, epithelial growth factor; NGAL, neutrophil gelatinase-associated lipocalin; OPN, osteopontin; UMOD, uromodulin; α-GST, α-glutathione-S-transferase.
