CKD may be defined based on decreased glomerular filtration rate (GFR) (< 60mL/min/1.73m2), increased urinary albumin excretion (UAE)[albumin-to-creatinine ratio (ACR) ≥ 30 mg/g or observation of albumin levels ≥ 30mg in 24-hour urinary protein tests] or abnormal imaging findings. This evidence concerns the gene ALB and chronic kidney disease.
