Kidneys help clear out the waste material remove the body and maintain different levels in the human body. The proper function of the kidneys is very important. A minor disorder of kidney function can disrupt various levels in the body and lead to various serious complications. To make sure your kidneys are healthy, you need to do a kidney function test at least once a year. A kidney function test helps the doctor to identify any kidney problems that can affect the proper functioning of the kidneys.

What is a kidney function test?

The kidney function test is done to see if your kidneys are in place or not. The kidney function test performs two types of tests, including ACR (Albumin-Creatinine Ratio) and GFR (Glomerular Filtration Rate). These tests are not so expensive and you can have your kidneys tested at least once a year.

ACR (albumin-creatinine ratio)

The person's urine is tested in the ACR test. ACR, d. H. albumin to creatinine ratio, verifies the presence of albumin in the urine. Albumin is a protein that is essential for the human body. This protein is produced by the liver, which should be present in your blood, not urine. So if albumin is found in the urine during the ACR test, it means that your kidneys are not functioning properly.

GFR (Glomerular Filtration Rate)

The presence of creatinine in the blood is examined in the GFR test. Creatinine is a chemical waste in the blood that should be filtered by the kidneys and excreted in the urine. If the kidneys do not separate this element from the blood, they will not work properly. Blood creatinine levels can be determined with a GFR test that indicates the severity of the damage.
