Microalbuminuria (MAU)
- Microalbuminuria (MAU) is a laboratory test for detecting minimal amounts of protein in urine.
- The test helps with early diagnosis of kidney damage, especially with diabetes mellitus, hypertension, and cardiovascular diseases.
- Particularly recommended for monitoring nephropathy risk and assessing kidney status.
What the test assesses:
- Albumin concentration in urine — early sign of kidney damage.
- Albumin-to-creatinine ratio — assessment of kidney functional status.
Biomaterial: Single morning urine sample
- Collect the first morning urine in a clean dry container.
- Avoid physical exertion and intensive fluid intake the day before.
Medications: if possible, avoid taking drugs affecting kidneys and urine protein (antibiotics, diuretics) 24-48 hours before the test.
Normal: albumin absent or present in minimal amounts (<30 mg/day).
Elevation (30-300 mg/day): microalbuminuria — early kidney damage.
High values (>300 mg/day): macroalbuminuria — pronounced kidney damage, requires nephrologist consultation.
