What’s wrong with having albumin (protein) in my urine?
One of the main jobs of your kidneys is to filter your blood. Your kidneys keep important things your body needs inside your blood, like protein. They also remove things your body doesn’t need, like waste products and extra water.
If kidneys are healthy, you should have very little protein in your urine – or even none. But if your kidneys are damaged, protein can “leak” out of the kidneys into your urine.
