Description
Serum, NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:
A random urine sample is required for this test. The sample is typically collected in the morning or as instructed by your healthcare provider.
Test Time:
The test results can usually be obtained within a few hours to a day, depending on the laboratory’s processing time.
Test Normal Range:
The normal range for the albumin/creatinine ratio is less than 30 milligrams of albumin per gram of creatinine (mg/g).
What is the Test?
The Albumin/Creatinine Ratio (ACR) is a laboratory test used to assess the amount of albumin in the urine in relation to the amount of creatinine. It provides an estimate of the level of albuminuria, which can indicate kidney dysfunction.
Test Procedure:
A random urine sample is collected, often in the morning. The sample is sent to a laboratory for analysis. The laboratory measures the amount of albumin and creatinine in the urine and then calculates the ACR by dividing the albumin level by the creatinine level.
When to Take the Test:
This test is commonly used to screen for kidney damage, especially in individuals with diabetes, hypertension, or other risk factors. It may also be part of routine health check-ups or monitoring for those with known kidney disease.
Who Should Take This Test:
People with diabetes, high blood pressure, or other conditions that can affect kidney function are often recommended to take this test. It’s also used to monitor individuals already diagnosed with kidney disease.
Precautions for Exceptional Cases:
Pregnant individuals and those with urinary tract infections should consult their healthcare provider before undergoing the test. The provider will determine if the test is appropriate and safe in these cases.
FAQs:
Q1: What does a high ACR indicate?
A: A high ACR suggests increased levels of albumin in the urine, which can be a sign of kidney damage or dysfunction.
Q2: Is ACR more accurate than spot urine albumin test?
A: ACR is often considered more accurate as it accounts for variations in urine concentration due to changes in fluid intake.
Q3: Can medications affect ACR results?
A: Some medications, like angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs), can lower ACR levels in people with diabetes.
Q4: How is ACR used to monitor kidney health?
A: ACR can help track the progression of kidney disease and assess the effectiveness of treatments and interventions.
Q5: Can a single high ACR result indicate kidney disease?
A: A single high ACR result might prompt further testing to confirm kidney dysfunction, as variations can occur due to temporary factors like dehydration or urinary tract infections.
