Referral to specialized kidney care services

Indication
AKI or abrupt sustained fall in GFR
GFR < 30 mL/min/1.73 m²
Consistent significant albuminuria (albumin/creatinine ratio ≥ 300 mg/g or albumin excretion rate ≥ 300 mg/24 h, equivalent to protein/creatinine ratio ≥ 500 mg/g or protein excretion rate ≥ 500 mg/24 h)
Progression of CKD (a drop in GFR from baseline by 25% or a sustained decline in GFR of more than 5 mL/min/1.73 m2/yr)

AKI: Acute kidney injury; GFR: Glomerular filtration rate; CKD: Chronic kidney disease.
