Urine albumin-to-creatinine ratio (ACR) is a test used to check for microalbuminuria, a sign of early kidney damage. It measures the amount of albumin, a type of protein, in your urine compared to creatinine, a waste product.
Here are some situations when urine ACR may be checked:
Who Should Get Urine ACR Tests?
- People with diabetes: Diabetes is a major risk factor for kidney disease. Regular urine ACR testing is recommended for people with diabetes, even if they have no other symptoms.
- People with high blood pressure: High blood pressure can also damage the kidneys. Urine ACR tests may be recommended for people with high blood pressure, especially if they have other risk factors for kidney disease.
- People with a family history of kidney disease: If you have a family member with kidney disease, you may be at increased risk. Your doctor may recommend urine ACR testing.
- People with certain medical conditions: Some medical conditions, such as lupus, can also damage the kidneys. Your doctor may recommend urine ACR testing if you have one of these conditions.
How Often Should Urine ACR Be Checked?
The frequency of urine ACR testing depends on your individual risk factors and medical history. Your doctor will recommend the best schedule for you.
What Does the Urine ACR Test Tell You?
A high urine ACR level can indicate that your kidneys are not working properly. This can be an early sign of kidney disease. If you have a high urine ACR level, your doctor may recommend further testing and treatment.
What Can You Do If Your Urine ACR Test Is High?
If your urine ACR test is high, your doctor may recommend lifestyle changes, such as:
- Controlling your blood sugar: If you have diabetes, it's important to control your blood sugar levels.
- Lowering your blood pressure: If you have high blood pressure, it's important to lower your blood pressure.
- Quitting smoking: Smoking can damage your kidneys.
- Eating a healthy diet: A healthy diet can help protect your kidneys.
Your doctor may also recommend medications to help protect your kidneys.
