Urinary NGAL Ratio Is Not a Sensitive Biomarker for Monitoring Acute Tubular Injury in Kidney Transplant Patients: NGAL and ATI in Renal Transplant Patients
(a) NGAL excretion in stable patients without ATI at 6 weeks, 3 months, and 6 months after transplantation. Shown is the urinary NGAL/creatinine ratio at 6 weeks (), 3 months (), and 6 months () in patients after kidney transplantation. (b) Individual course of NGAL excretion of the stable patients at 6 weeks, 3 months, and 6 months after transplantation. Depicted are single measurements ( at 6 weeks, at 3 months, at 6 months) as single black squares and serial measurements (6 weeks to 3 months: patients, 3 months to 6 months: patients, and 6 weeks to 3 months and 6 months: patients) as open circles connected by lines. Total measurements at 6 weeks: , at 3 months: , and 6 months: .
