More recently, other markers, including presepsin, a fragment of CD14; procalcitonin, currently recognized as suitable markers for the diagnosis of sepsis or severe sepsis [61]; neutrophil gelatinase-associated lipocalin (NGAL) [62]; soluble endothelial selectin (E-selectin); ICAM-1; VCAM-1; and urinary albumin-to-creatinine ratio (ACR), have particularly been considered in AKI diagnosis and prognosis [25,42]. The gene discussed is LCN2; the disease is acute kidney injury.
