Urinary NGAL Ratio Is Not a Sensitive Biomarker for Monitoring Acute Tubular Injury in Kidney Transplant Patients: NGAL and ATI in Renal Transplant Patients

Figure 3

(a) Comparison of urinary NGAL/creatinine ratios in patients with and without ATI after kidney transplantation. Patients with ATI 6 weeks ( ) after transplantation have significantly higher urinary NGAL levels than patients without ATI ( ). In patients with ATI, the urinary NGAL excretion at 6 months ( ) is significantly lower than at 6 weeks. No difference in uNGAL ratios was seen between patients with and without ATI at 6 months. (b) Individual course of NGAL levels in patients with ATI at 6 weeks and 6 months after transplantation. Patients with singular measurement are presented by single values only (dots; patients for the 6-month measurements). Serial measurements: patients for 6 weeks and 6 months (connected by lines).
