Interestingly, Bachorzewska-Gajewska recently demonstrated a rise in urinary NGAL 4 hours following the administration of contrast during percutaneous coronary angioplasties in 25 adult patients (from 11.1 μg/L +/−15.8 to 17.8 +/− 34.48, p < 0.05) despite however any significant change in average serum creatinine values.84 These studies thus suggest a very promising role for NGAL in the early evaluation of ARF which will require further investigations. Here, LCN2 is linked to acute kidney injury.
