Albumin Creatinine Ratio Test
The urine albumin-to-creatinine ratio (ACR) test is a simple and noninvasive test that measures the amount of albumin (a protein) in the urine compared to the amount of creatinine (a waste product) in the urine. It is used to screen for and monitor kidney disease, as well as to monitor diabetes and hypertension. Elevated levels of albumin in the urine may indicate that the kidneys are not functioning properly and may be a sign of early kidney disease. The ACR test is usually performed as part of a routine physical exam and is often used in conjunction with other tests, such as a creatinine test, to assess kidney function.
Whom the Urine ACR Test Advised?
The urine albumin-to-creatinine ratio (ACR) test is typically recommended for individuals who are at an increased risk of developing kidney disease. This includes people with diabetes, hypertension, and a family history of kidney disease. It is also recommended for people who have already been diagnosed with kidney disease and are being monitored for disease progression.
Additionally, the ACR test is also recommended as part of a routine check-up for people over the age of 60, pregnant women and obese people. People who take long-term medication for conditions such as hypertension, heart disease and diabetes may also be advised to take the test.
It is important to note that the ACR test is not a diagnostic test for kidney disease, and a positive test result does not necessarily mean that an individual has kidney disease. Other tests, such as a creatinine test, a urinalysis, or a kidney biopsy may be necessary to make a diagnosis.
Urine ACR Test Preparation
There is usually no special preparation required for a urine albumin-to-creatinine ratio (ACR) test. However, some general guidelines to follow include:
- Avoiding vigorous exercise for 24 hours before the test, as this can affect the results.
- Not taking any over-the-counter medications, vitamins, or supplements for 24 hours before the test.
- Avoiding drinking alcohol or caffeine for 24 hours before the test.
- Collecting a “clean-catch” urine sample. This means spotless the area around the urethra and then passing urine into a clean container, discarding the first few millilitres and then collecting the midstream urine
It is important to follow any specific instructions provided by your healthcare provider or the laboratory that will be performing the test. It is also important to inform the healthcare provider or lab of any medications you are currently taking, as these may affect the results of the test.
Urine ACR Test Conditions
There are certain conditions that can affect the results of a urine albumin-to-creatinine ratio (ACR) test and make them inaccurate. These include:
- Urinary tract infections (UTIs): UTIs can cause an increase in the amount of protein in the urine, which can lead to a false positive result on the ACR test.
- Dehydration: When the body is dehydrated, the concentration of creatinine in the urine can increase, which can lead to a false positive result on the ACR test.
- Menstruation: Hormonal changes during menstruation can cause an increase in the amount of protein in the urine, which can lead to a false positive result on the ACR test.
- Exercise: Vigorous exercise can cause an increase in the amount of protein in the urine, which can lead to a false positive result on the ACR test.
- Medications: Certain medications, such as ACE inhibitors and nonsteroidal anti-inflammatory drugs (NSAIDs), can cause an increase in the amount of protein in the urine, which can lead to a false positive result on the ACR test.
It is important to inform your healthcare provider or the laboratory of any conditions or medications that may affect the results of the test, as well as any other relevant information such as recent exercise, menstruation, and hydration level to ensure that the results of the test can be interpreted correctly.
