Table 3.

Classification of albuminuria in patients. Albuminuria is classified as A1 (normoalbuminuria), A2 (microalbuminuria) or A3 (macroalbuminuria). The relevant values for urinary albumin excretion rate (UAER), urinary albumin creatinine ratio (UACR) and albumin creatinine ratio (ACR), as well as the albuminuria severity banding, are indicated

Category	UAER (mg/24 h)	UACR (mg/mmol)	ACR (mg/g)	Severity	Classification
A1	< 30	< 3	< 30	Normal to mildly increased	Normoalbuminuria
A2	30–300	3–30	30–300	Moderately increased	Microalbuminuria
A3	> 300	> 30	> 300	Severely increased	Macroalbuminuria
