Microalbumin (Urine)
Understand Microalbumin in urine for early kidney damage detection. Monitor diabetic nephropathy risk with precision tracking.
What is Microalbumin (Urine)?
Microalbumin is a urine test that measures small amounts of the protein albumin. Normally, healthy kidneys prevent albumin from leaking into urine, so its presence—even in tiny amounts—can signal early kidney damage.
Why is it Tested?
Healthcare providers use microalbumin screening to detect kidney disease in its earliest stages, particularly in people with diabetes or high blood pressure. Early detection allows for treatment that can slow or prevent kidney damage progression.
Normal Ranges
Reference ranges for adults:
- Normal: Less than 30 mg/L
- Microalbuminuria: 30–300 mg/L (early kidney damage)
- Macroalbuminuria: Greater than 300 mg/L (significant kidney damage)
Reference ranges vary by authority. Track yours across multiple standards with automatic unit conversions in LabsVault.
What do Abnormal Results Mean?
Abnormal results are not a diagnosis. Always discuss your results with a qualified healthcare provider before making any medical decisions.
Microalbuminuria (30-300 mg/L)
Elevated microalbumin at this level may indicate:
- Early diabetic nephropathy
- Beginning kidney damage from high blood pressure
- Increased cardiovascular disease risk
- Need for closer monitoring and treatment
Macroalbuminuria (>300 mg/L)
High levels suggest more advanced kidney problems:
- Established diabetic kidney disease
- Significant nephropathy requiring treatment
- Advanced chronic kidney disease
- Higher risk of kidney failure
How to Track Over Time
Tracking microalbumin levels helps catch kidney disease before irreversible damage occurs. Consistently rising levels indicate progressive kidney damage, while stable or decreasing levels suggest successful treatment or good disease control.
