In a small cross‐sectional study, Gerbes et al.20evaluated the relationship between measured glomerular filtration rate (via 51Cr‐EDTA technique) with plasma and uNGAL in patients with decompensated cirrhosis and variable kidney function; this showed that a cut‐off of plasma NGAL>100 ng/mL was superior to creatinine in predicting patients with measured glomerular filtration rate (GFR) < 50 mL/min. This evidence concerns the gene LCN2 and Cirrhosis.
