LCN2 and glycogen storage disease VI: Despite its reported association with tubular damage and slight to moderate correlation with the tubular disease score obtained from histologic examination of the kidneys (0.3395 for NGAL normalized against creatinine and 0.2934 for NGAL normalized against osmolality), no difference was observed in urine NGAL normalized against creatinine (P = 0.4443) among the exposure groups, or between single or combination exposed animals compared to the No iAs/No TCE group.
