For example, median [90th percentile range] GFR in healthy and severe CKD were 114 [87.3–166] mL/min and 21.0 [16.9–26.6] mL/min, respectively; corresponding values for human serum albumin were 46.4 [38.9–54.6] μmol/L and 36.7 [29.2–44.2] μmol/L, respectively. Here, ALB is linked to chronic kidney disease.
