Chronic kidney disease (CKD) is defined as abnormalities of renal structure or function, present for >3 months, with implications for health.1 The most commonly used diagnostic criteria in clinics are estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2 or urinary albumin-to-creatinine ratio (ACR) ≥ 30 mg/g. Here, ALB is linked to chronic kidney disease.
