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 2

(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 (𝑛=23), 3 months (𝑛=17), and 6 months (𝑛=16) 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 (𝑛=13 at 6 weeks, 𝑛=2 at 3 months, 𝑛=4 at 6 months) as single black squares and serial measurements (6 weeks to 3 months: 𝑛=4 patients, 3 months to 6 months: 𝑛=5 patients, and 6 weeks to 3 months and 6 months: 𝑛=6 patients) as open circles connected by lines. Total measurements at 6 weeks: 𝑛=23, at 3 months: 𝑛=17, and 6 months: 𝑛=16.
