Significance of Microalbuminuria (MAU) test

Microalbuminuria (MAU) test helps in early diagnosis of kidney diseases when detecting risk factors such as hypertension, diabetes. From there, it is possible to devise a treatment method to control the risk of kidney disease early.

Microalbuminuria is a test for microalbuminuria (albumin excreted in the urine in very small amounts) that is not detected by routine urine tests. There is almost no albumin in the urine of normal people. The presence of albumin in the urine is a sign that the kidneys are not working well. Therefore, microalbuminuria test will help in early diagnosis of kidney abnormalities.

Microalbuminuria helps in early diagnosis of kidney diseases. Therefore, if kidney damage is suspected, the doctor will order this test. Some causes of kidney damage that need to be tested for microalbuminuria include:
Hypertension: Frequent high blood pressure can damage the blood vessels in the kidneys, causing albumin to be poorly filtered, Some are excreted in the urine. Diabetes: People with diabetes are usually assigned to have a microalbuminuria test once a year and starting 5 years from the time of diagnosis. It is often indicated together with blood glucose, HbA1c, and urinary creatinine to control and slow the progression of diabetic nephropathy. Bacterial and viral infections: The inflammatory response can cause albumin to escape into the glomerular capillaries, causing albumin to appear in the urine. Metabolic syndrome: Low HDL, high triglycerides, abdominal obesity, insulin resistance (the main signs for the diagnosis of metabolic syndrome) are often accompanied by the presence of urinary albumin. Endothelial dysfunction: Increased levels of endothelial dysfunction agents such as Von Willebrand, thrombomodulin, and Angiotensin-activated factor VII increase the risk of microalbuminuria. People over 65 years of age with risk factors for cardiovascular disease and kidney disease People with family members with kidney disease In addition, microalbuminuria is also indicated in pregnant women, pre-eclampsia and urinary tract infections ...

Microalbuminuria results
The normal value of microalbuminuria on random urine testing is < 20 mg/L and 24-hour urinalysis is < 30 mg/24 hours. Higher than this value is called microalbuminuria.
Microalbumin test results can be affected by a number of factors such as medication, fever, intense exercise, urinary tract infections and other kidney diseases, blood in the urine, etc. ..
Microalbuminuria is not only an important subclinical test indicator in early detection of kidney disease, but also an extremely necessary subclinical indicator in a number of other dangerous medical diseases such as kidney disease. Cardiovascular disease, diabetes, hypertension... Therefore, in addition to assessing kidney damage or pathology, microalbuminuria test should also be performed when the patient has risk factors for these diseases. internal medicine mentioned above.
