The Vital Importance of the Microalbuminuria Test: What You Should Know
What is a microalbuminuria (MAU) test?
You probably have or will have a test if your doctor thinks you could be at risk for kidney illness or damage. The test determines how much albumin is in your urine through a urine sample.
Your body requires the protein albumin to support tissue repair and cell proliferation. It typically exists in blood. It may indicate kidney impairment if your urine contains a particular amount of it.
Your kidneys are in charge of eliminating waste from your blood and controlling your body’s water balance. Maintaining healthy kidneys ensures that waste products are removed from the body and that vital minerals and proteins, such albumin, remain in your body.
To ensure that albumin stays in your blood, it’s critical to check the health of your kidneys. Albumin may start to leak into your urine if your kidneys are damaged and are unable to maintain it in your blood. When this happens, you could have an illness called albuminuria. To put it simply, albuminuria is the presence of albumin in the urine.
The albumin-to-creatinine ratio (ACR) test and the urine albumin test are other names for the MAU test.
What is the purpose of the test?
If you are at risk for kidney disease or your doctor suspects you may have kidney impairment, they may suggest a MAU test. If your kidneys are damaged, it’s critical that your doctor test and identify you as soon as possible.
Nephropathy may be postponed or prevented with treatment. In the Singapore, hypertension, or high blood pressure, and diabetes are the two main causes of kidney damage. If you have any of these problems, your doctor might request that you have a microalbuminuria test.
The MAU test is used to quantify the amount of albumin present in urine. To determine the albumin-to-creatinine ratio, the test is usually utilised in conjunction with a creatinine test. Your kidneys are supposed to filter out waste products like creatinine from your blood. Urine creatinine levels drop and albumin levels may rise in cases of renal injury. The existence of symptoms indicative of kidney impairment or underlying medical problems influences the frequency of MAU tests.
Kidney disease in its early stages typically exhibits no symptoms at all. But if you have severe kidney injury, your pee could look frothy. Additionally, you could develop edema, or swelling, in your:
It is advised that diabetics get a MAU test once a year. This is due to the possibility of renal damage from diabetes. A MAU test is one tool your doctor might use to identify this damage.
Your doctor should order more testing over a three- to six-month period to confirm the results if you have diabetes and have positive test results. In the event that kidney damage is confirmed, your doctor can treat the kidney injury and enhance and maintain the function of your kidneys.
High blood pressure
Your doctor may use the MAU test to check for kidney damage if you have high blood pressure. High blood pressure has the potential to harm kidney arteries, which can lead to albumin leakage into the urine. Regular intervals should be observed while testing for albumin. When you require this test will be decided by your doctor.
Preparation for the test
A straightforward urine test is the MAU test. Before the test, you can eat and drink as usual. For this test, there is no need for further preparation.
How is the test administered?
Several types of MAU urine tests are available:
Random urine test
Urine testing can be done at any moment at random. In order to increase the accuracy of the results, doctors frequently combine it with a creatinine test. This test is available in any medical facility. You will get the sample in a sterile cup, which your doctor will then send off to a lab for examination.
24-hour urine test
You must collect all of your urine over the course of a 24-hour period for this test. You will receive a urine collection container from your doctor that needs to be refrigerated. Urine must be collected for 24 hours, and then the sample must be sent to your healthcare professional for laboratory analysis.
Timed urine test
If you don’t urinate for four hours period, your doctor could ask you to produce a urine sample first thing in the morning.
Your doctor will be able to provide you further details regarding the results and their significance as soon as the lab returns the results.
What are the risks of the test?
All that is needed for the MAU test is normal urine. You shouldn’t experience any discomfort during this test, and there are no dangers.
Understanding your results
An excessive amount of albumin in the urine is known as albuminuria. A slightly highquantity of protein in the urine is known as MAU, but a daily high level of albumin in the urine is known as macroalbuminuria. The MAU test measures the amount of protein that leaked into your urine over a 24-hour period in milligrammes (mg). The following is often indicated by the results:
- Less than 30 mg of protein is normal.
- Thirty to 300 mg of protein is known as MAU, and it may indicate early kidney disease.
- More than 300 mg of protein is known as macroalbuminuria, and it indicates more advanced kidney disease.
Several temporary factors can cause higher-than-normal urinary MAU results, such as:
- blood in your urine, or hematuria
- a fever
- recent vigorous exercise
- a urinary tract infection
Certain medications can also affect albumin levels in your urine. Examples include:
- acetazolamide (Diamox Sequels)
- antibiotics, including aminoglycosides, cephalosporins, penicillin, polymyxin B, and sulfonamides
- antifungal medications, including amphotericin B (Abelcet) and griseofulvin (Gris-PEG)
- lithium, which is a medication people use to treat bipolar disorder
- nonsteroidal anti-inflammatory drugs (NSAIDs) like aspirin (Bufferin), ibuprofen (Advil), and naproxen (Aleve)
- penicillamine (Cuprimine), which is a medication people used in the past to treat rheumatoid arthritis
- phenazopyridine (Pyridium), which is a medication people use to treat urinary tract pain
- tolbutamide, which is a medication people use to treat diabetes
If the initial test yields abnormal results, your doctor might wish to do another urine test once the data have been processed. Your doctor will advise the best course of action for treating your kidney impairment and its underlying cause, if necessary.
To determine whether kidney damage is present, it is crucial to measure the amount of albumin in your urine. Kidney failure or disease can result from kidney injury. Dialysis is frequently required in the event of renal failure. Your doctor can prevent kidney failure by detecting kidney disease early on, which will assist to prevent future damage and maintain kidney function over time.
Measuring the amount of albumin in your urine is important for detecting the presence of kidney damage. Kidney damage can lead to kidney disease or failure. If kidney failure occurs, dialysis is often necessary. By identifying kidney damage before it results in kidney failure, your doctor can slow the progression of any further damage and help preserve your kidney function over the long term.
