In 1999-2016, <10% of those with eGFR ≥60 ml/min/1.73 m² with albuminuria (single random measurement) were aware of having CKD. Reported awareness was estimated to be higher for those with stage 3B (eGFR 30-44) at 28% compared to those with CKD stage 3A (eGFR 45-59) at 11%. For stage 4 (eGFR 15-29), 53.6% reported being aware of their disease.
Those with evidence of albuminuria, particularly an albumin:creatinine ratio ≥300 mg/g (macroalbuminuria), were generally more likely to be aware of their CKD condition (15% in 2005-2010 to 20% in 2011-2016).
