Definitions of abnormalities in albumin excretion
| Category | Spot collection (μg/mg creatinine) |
| Normal | <30 |
| Increased urinary albumin excretion* | ≥30 |
Historically, ratios between 30 and 299 have been called microalbuminuria and those 300 or greater have been called macroalbuminuria (or clinical albuminuria).
