In diabetic patients, DKD diagnosis is traditionally made when one or more of the following signs is present over a span of three months: a decreased eGFR (<60 ml/min/1.73 m2), an increase in daily albumin excretion in urine (≥30 mg), or an increase in the urinary albumin/creatinine ratio (≥30 mg g−1) [5]. Here, ALB is linked to diabetic kidney disease.
