A study by Khalid et al.10 in 2016 showed that the endothelial, glomerular, tubular, and interstitial (EGTI) scoring system provides a more comprehensive assessment of kidney injury due to RIRI where it was found that the EGTI scoring system correlated significantly with serum creatinine and also AKI markers such as NGAL and KIM-1. Here, LCN2 is linked to acute kidney injury.
