The UACR test is one of the most useful kidney checks for people with diabetes. UACR stands for urine albumin-to-creatinine ratio. It looks for albumin, a protein that can leak into the urine when kidney filters are under stress.
Quick summary
A normal eGFR does not always mean the kidneys are completely safe. UACR can show early kidney damage before symptoms appear.
Key takeaways
- UACR is a urine test that checks for albumin leakage.
- It is often used together with eGFR, a blood-based estimate of kidney filtering.
- High UACR can be temporary, so repeat testing may be needed.
- Blood pressure, glucose, kidney-protective medicines, and smoking cessation can reduce risk for many people.
Why UACR matters
Diabetic kidney disease can be silent for years. Albumin in the urine may appear before a person feels unwell or before eGFR falls. That makes UACR a practical early warning test.
Results need context. Exercise, fever, infection, high blood sugar, uncontrolled blood pressure, and menstruation can affect a urine result. Clinicians often repeat abnormal tests before making long-term decisions.
What to ask about your result
- What was my UACR number?
- Was it normal, moderately increased, or severely increased?
- Should it be repeated?
- What was my eGFR at the same time?
- Should my blood pressure medicine, SGLT2 inhibitor, or other kidney-protection plan be reviewed?
Practical takeaway
Ask for both kidney numbers by name: UACR and eGFR. One urine result is not the whole story, but it can start an important prevention conversation.

What to ask your care team
- What do my latest kidney numbers mean for my diabetes plan?
- Which symptoms, medicine changes, or test results should prompt urgent care?
- Do my blood pressure, glucose, nutrition, or medicine goals need adjustment?
