CKD may be defined by abnormal urinary albumin excretion (at least 30 mg per 24 h or albumin to creatinine ratio at least 30 mg/g creatinine), decreased glomerular filtration rate (GFR) less than 60 mL/min/1.73 m2, and markers of kidney damage, including hematuria or structural abnormalities by imaging persisting for more than 3 months1,3. Here, ALB is linked to chronic kidney disease.
