Albumin/Creatinine Ratio (Urine)
The urine albumin-to-creatinine ratio (UACR) compares albumin to creatinine in a spot urine sample. It is the preferred screening test for early kidney damage, especially in patients with diabetes.
Category: Urinalysis
Also known as: urine acr, uacr, urine albumin creatinine ratio, urine albumin/creatinine ratio, urine microalbumin creatinine ratio
Reference range: 0–30 mg/g (Source: ABIM)
Standard unit: mg/g
High values may indicate
High UACR may indicate early kidney damage (microalbuminuria or macroalbuminuria), diabetic nephropathy, hypertensive kidney disease, or glomerulonephritis.
Low values may indicate
Low UACR is normal and indicates healthy kidney filtration without significant albumin leakage.
Frequently asked questions
- What is a normal Albumin/Creatinine Ratio (Urine) level?
- A typical reference range for Albumin/Creatinine Ratio (Urine) is 0–30 mg/g (source: ABIM). Reference ranges vary by laboratory, age, and sex, so always compare against the range on your own lab report.
- What units is Albumin/Creatinine Ratio (Urine) measured in?
- Albumin/Creatinine Ratio (Urine) is most commonly reported in mg/g. Labs in different countries may use other units — you can convert between them with BloodId's blood test unit converter.
- Where do Albumin/Creatinine Ratio (Urine) reference ranges come from?
- BloodId uses ABIM standard reference ranges and educational information from MedlinePlus (see our methodology). Reference ranges still vary by lab, age, and sex, so always compare against your own report.
- Can I track Albumin/Creatinine Ratio (Urine) over time?
- Yes. Upload results from any lab and BloodId charts your Albumin/Creatinine Ratio (Urine) over time against its reference range, so you can see whether the trend is rising, falling, or stable.
