Table 1 Common biomarkers for acute kidney injury in traumatic brain injury
| Biomarker | Specimen sample | Remarks |
| Neutrophil gelatinase-associated lipocalin | Plasma and urine | Released from damaged tubular epithelial cells |
| Kidney injury molecule 1 | Urine | Transmembrane glycoprotein released from damaged tubular epithelial cells |
| Liver-type fatty acid-binding protein | Plasma and urine | 14 kDa cytoplasmic transporter for free fatty acids in proximal tubular epithelial cells |
| Interleukin-18 | Urine | Pro-inflammatory cytokine released from stressed proximal tubular epithelial cells |
| Tissue inhibitor of metalloproteinases-2; insulin-like growth factor-binding protein 7 (NephroCheck™) | Urine | Metalloproteinases released from stressed tubular epithelial cells during cell cycle arrest |
