Who should get tested?

More than 1 in 7 adults, about 30 million, in the US have Chronic Kidney Disease (CKD), but most (96%) people with mild kidney damage are not aware of having CKD.¹ During the early stages of CKD there may be no symptoms, the best way to protect yourself from kidney disease is to know the risk factors and get tested routinely. Some of the risk factors for CKD include:²

  • Diabetes
  • High blood pressure
  • Family history of kidney disease
  • >60 years old
