Some diseases and conditions put children at risk for kidney disease. A urine test is used to check for kidney disease before symptoms appear. Read more to learn about risk factors, the urine test, and treatment for kidney disease.
Your child has two kidneys. Their main job is to filter wastes and extra water from the blood. Wastes and water pass through the kidneys and leave the body as urine. The kidneys also make hormones that help the body make blood and keep the bones strong.
Infections or other health problems can cause kidney disease. When a child has kidney disease, the kidneys may not work normally. This may lead to a harmful buildup of wastes in the body.
A urine test can be used to check for kidney disease if your child is at risk. Testing is important because early kidney disease often has no symptoms. Your child will urinate in a cup, and the sample will be tested for kidney disease.

If your child’s kidneys are damaged, small amounts of albumin can pass into the urine through the kidneys. In general, the more albumin there is in the urine, the more damaged the kidneys are.
A high urine albumin level may mean that your child has kidney disease. Your health care provider may do other tests for kidney disease, including a blood test, which checks how well the kidneys are filtering.
