FABP1 and kidney disorder: Staging of T2D patients by eGFR and urinary albumin and assessing urinary L-FABP levels in patients with different albumin levels showed that urinary L-FABP levels were significantly higher in diabetic patients with normal urinary albumin than in normal controls in the presence of renal impairment, suggesting that urinary L-FABP detects renal disease in diabetic patients earlier than urinary albumin (Thi et al., 2020).
