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) Urinary NGAL/creatinine ratio depending on the frequency of ATI. Shown is the urinary NGAL/creatinine ratio depending on whether patients had 1 time (), 2 times (), or 3 times () findings of ATI in biopsies taken while being followed in the biopsy program. (b) Urinary NGAL/creatinine ratio in Tx patients with focal versus diffuse ATI. No significant differences were found in the urinary NGAL excretion of patients with focal () versus diffuse () ATI findings after Tx.
