The pooled sensitivity and specificity for kidney disease in normoalbuminuric patients with diabetes were 0.90 (0.82–0.95) and 0.97 (0.90–0.99) for serum NGAL, respectively, and 0.94 (0.87–0.98) and 0.90 (0.81–0.96) for urine NGAL, respectively [45]. The gene discussed is LCN2; the disease is kidney disorder.
