Early kidney disease usually does not have signs (a change in your body) or symptoms (a change in how you feel). Testing is the only way to know how your kidneys are doing. It is important for you to get checked for kidney disease if you have the key risk factors – diabetes, high blood pressure, heart disease, or a family history of kidney failure.
Two tests are needed to check for kidney disease.
1. A blood test checks your GFR, which tells how well your kidneys are filtering. GFR stands for glomerular (glow-MAIR-you-lure) filtration rate.
2. A urine test checks for albumin in your urine. Albumin is a protein that can pass into the urine when the kidneys are damaged.
It is also important to have your blood pressure checked. High blood pressure can be a sign of kidney disease. Keep your blood pressure at or below the target set by your health care provider. For most people, the blood pressure target is less than 140/90 mm Hg.
The sooner you know you have kidney disease, the sooner you can get treatment to help delay or prevent kidney failure. If you have diabetes, get checked every year. If you have other risk factors, such as high blood pressure, heart disease, or a family history of kidney failure, talk to your provider about how often you should be tested.
