High Urine albumin-creatinine ratio (UACR): what it means
A Urine albumin-creatinine ratio (UACR) result above the normal range is considered high. Here is what a raised Urine albumin-creatinine ratio (UACR) can point to, and when it is worth discussing with a doctor.
Reference range: <30 mg/g normal; 30–300 = moderately increased (early kidney damage); >300 = severely increased. A single-sample urine test that flags leaking albumin

What a high Urine albumin-creatinine ratio (UACR) can mean
- Moderately increased albumin (30–300 mg/g) — the earliest routine sign of kidney damage, often called microalbuminuria; common in diabetes and high blood pressure.
- Severely increased albumin (>300 mg/g) — more advanced kidney damage or heavy protein leak, overlapping with proteinuria.
- Diabetic or hypertensive kidney disease — the classic settings where UACR is monitored.
- Glomerular disease — inflammation or damage of the kidney filters.
- Transient causes — fever, urinary infection, heavy exercise, or menstrual contamination; a reason to repeat before acting.
When to discuss with a doctor
A raised urine albumin-creatinine ratio is one of the most useful early warnings in medicine, because it can flag kidney damage before symptoms and before eGFR falls, and it also marks higher cardiovascular risk. In people with diabetes or high blood pressure it is checked routinely, and a persistently raised value usually prompts kidney-protective steps such as tighter blood-pressure and glucose control and specific medicines. Because a single raised result can come from a passing cause like infection, fever, exercise or menstrual blood, it is normally confirmed on one or two repeat samples before conclusions are drawn. A very high ratio, or a rising trend, warrants closer assessment. Mediora.AI shows UACR alongside creatinine, eGFR and urine protein so the early-kidney-damage pattern is visible over time; interpreting it and deciding on treatment belongs with your doctor.
How to bring a high Urine albumin-creatinine ratio (UACR) down
- Manage blood pressure and blood sugar - Keeping these under control can often help reduce UACR levels, especially in diabetes and hypertension.
- Adopt a kidney-friendly diet - Focus on reducing salt intake and eating a balanced diet rich in fruits and vegetables to support kidney health.
- Maintain a healthy weight - Achieving and maintaining a healthy weight can help reduce the strain on your kidneys.
- Consult your doctor - A healthcare provider can review your medications and overall health to address underlying causes effectively.
