Chronic kidney disease (CKD), a longstanding disease, means a patient’s kidneys get damaged and are not able to filter blood the way they should. It is known as Chronic Kidney Failure. This disease involves a gradual loss of your kidney function. CKD can cause wastes to build up in a person’s body. It can also cause other major problems that can harm his/her health. This damage occurs gradually over many years. Many people cannot see any symptoms until their CKD is very advanced. Blood & Urine Tests are the possible ways to know if a person suffers kidney disease.
